  • Trying to add functionality to MvcHandler

    - by Alexandre Brisebois
    I am currently trying to add 301 redirect to my routes in MVC to do this I have tried to inherit from the MvcHandler. The handler gets instantited with the right values. but I am never able to debug the overridden methods. can someone show me a working attempt at this? the asp.net pipe simply seems to the doing its own thing... public class CodeHttpHandler : MvcHandler { public CodeHttpHandler(RequestContext p_requestContext) : base(p_requestContext) { } protected override void ProcessRequest(HttpContext p_httpContext) { } protected override void ProcessRequest(HttpContextBase p_httpContext) { } }

  • "Does not implement IControllerFactory.CreateController" in Visual Studio 2010 RC

    - by ripper234
    When compiling this code: public class WindsorControllerFactory : IControllerFactory { private readonly WindsorContainer _container; public WindsorControllerFactory(WindsorContainer container) { _container = container; } public IController CreateController(RequestContext requestContext, string controllerName) { return (IController)_container.Resolve(controllerName); } public void ReleaseController(IController controller) { _container.Release(controller); } } I am getting this error: 'WindsorControllerFactory' does not implement interface member 'System.Web.Mvc.IControllerFactory.CreateController(System.Web.Routing.RequestContext, string)' Well, it obviously implements this member. Has anyone encountered this problem?

  • ASP.NET LINQ to SQL SubmitChanges() doesn't update the database

    - by Alex
    In my 2nd ASP.NET MVC project I'm facing a very weird problem: when I call the SubmitChanges method of the DataContext class, nothing updates in the database. It's weird because everything works fine with my first project. I'm using a remote database created in Sql Server Management Studio, I tried doing some queries there and in Visual Studio 2010 (where I have the connection to the database), they all work. Where might the problem be hidden?

  • ASP.NET MVC2 Routing Issue With StructureMap

    - by alphadogg
    So, in global.asax, I have: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute(" { *favicon }", new { favicon = @"(.*/)?favicon.ico(/.*)?" }); routes.IgnoreRoute("{*robotstxt}", new { robotstxt = @"(.*/)?robots.txt(/.*)?" }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); } protected void Application_Start() { var container = new Container(); ServiceLocator.SetLocatorProvider(() => new StructureMapServiceLocator(container)); ComponentRegistrar.Register(container); Debug.WriteLine(container.WhatDoIHave()); // original MVC2 code at project startup AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); } and in my StructureMapControllerFactory, I have: protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (requestContext == null) { throw new ArgumentNullException("requestContext"); } if (controllerType == null) { //return base.GetControllerInstance(requestContext, controllerType); controllerType = GetControllerType(requestContext, "Home"); requestContext.RouteData.Values["Controller"] = "Home"; requestContext.RouteData.Values["action"] = "Index"; } try { return theContainer.GetInstance(controllerType) as Controller; } catch (StructureMapException) { System.Diagnostics.Debug.WriteLine(theContainer.WhatDoIHave()); throw; } } Now, normally, in most examples you find on the net, when controllerType is null, you have the commented out line (base.GetControllerInstance()) that handles it. However, if I use that, I get an error about not finding the controller for default.aspx when the controllerType is null at startup of the web app. If I force the use of the Home controller, I get the site to appear. What am I doing wrong? Is it a problem in routing?

  • What can't I build in Silverlight?

    - by Refracted Paladin
    First, I know that Silverlight needs to be embedded in a website, usually an asp page. I understand I need a delivery boy. My question is this; What types of apps/projects are so filled with technological hurdles as to make them ridiculous to do in Silverlight versus ASP.net? I know that with perseverance and flexibility I can probably make EVERY app in Silverlight, in some version or another, but which ones would be blatantly simple in, say ASP.net(or even WPF) but quite complicated in Silverlight? Basically what I am asking is if there is any reason I shouldn't consider Silverlight my first stop for every problem, obvious exceptions not with standing(a service or console). For me specifically, at this point, I am only building in house apps.

  • Can't find controls in FormView.InsertItemTemplate even on DataBound event

    - by abatishchev
    I have FormView in my page markup: <asp:FormView ruanat="server" ID="FormView1" OnDataBound="FormView1_DataBound" DataSourceID="SqlDataSource1"> <InsertItemTemplate> <uc:UserControl1 runat="server" ID="ucUserControl1" /> </InsertItemTemplate> </asp:FormView> <asp:SqlDataSource runat="server" ID="SqlDataSource1" SelectCommand="EXEC someSP" /> It's code-behind: protected void FormView1_DataBound (object sender, EventArgs e) { var c1 = ((FormView)sender).FindControl("ucUserControl1"); // returns null var c2 = FormView1.FindControl("ucUserControl1"); // also returns null } In theory, I'm able to find control on FormView after it being data bound. But I'm not. Why?

  • Why doesn't a LinkButton work with a table as it's content?

    - by Telos
    Using ASP.NET 3.5, you can create a LinkButton then define content inside of it. It works fine if I have div tags or any kind of text or anything, but if I use a table the click doesn't actually post back for some reason. This should take you to google (you'll get an error there but it should still go) for instance: <asp:LinkButton ID="lbTest" PostBackUrl="http://www.google.com" runat="server"> <table> <tr> <td>Test</td> <td>col2</td> <td>col3</td> </tr> </table> </asp:LinkButton> I could work around it by building a "table" with divs I guess, but I hate formatting with divs.

  • Is it possible to reference a linkbotton outside an update panel as the update trigger?

    - by Selase
    I have a page based on a master page and as such i can only see the content place holders i used in the master page showing up in the aspx pages based on the master page. the source code shown below: <%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="CaseAdmin.aspx.cs" Inherits="Prototype4.CaseAdmin" %> <%@PreviousPageType VirtualPath="~/Account/Login.aspx"%> <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> </asp:Content> <asp:Content ID="CaseRightNews" ContentPlaceHolderID="RightNewsItem" runat="server"> </asp:Content> <asp:Content ID="CaseLeftNav" ContentPlaceHolderID="LeftNavigation" runat="server"> <div style="margin-top:20px; margin-bottom:20px;"> <p class="actionButton"> <asp:LinkButton ID="OpenCaseLinkButton" runat="server" onclick="OpenCaseLinkButton_Click">Open Case</asp:LinkButton> </p> <p class="actionButton"><asp:LinkButton ID="RegisterExhibitLinkButton" runat="server" onclick="RegisterExhibitLinkButton_Click">Register Exhibit</asp:LinkButton> </p> </div> </asp:Content> <asp:Content ID="CaseMainContnt" ContentPlaceHolderID="MainContent" runat="server"> <asp:ScriptManager ID="ScriptManager" runat="server" /> <asp:UpdatePanel ID="CaseMainCntntUpdatePanel" UpdateMode="Conditional" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="" eventname="Click"/> </Triggers> <ContentTemplate> <%--Some text here to inform user to click on the open case botton to display open case form--%> </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel runat="server" id="UpdatePanel1" updatemode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="" eventname="Click"/> </Triggers> <ContentTemplate> <%--some text here to inform users to click on the add exhibit botton to display add exhibit form--%> </ContentTemplate> </asp:UpdatePanel> </asp:Content> the section of the entire page i wish to change upon update is the (this is the main content of the page). for this reason i placed the updatepanel inside the content place holder since it cant be sitting outside and not wrapped in a content place holder. However, the buttons that i wish to apply the trigger that fires the update to, are in another content place holder(). How can i possibly get those buttons to act as the trigger while changing only what appears in the main content area. Plus, i tried getting the updatepanel to work just so i could see if it does the update well but it turned out really bad. i added some linkbottons in the content template area and used them as the triggers for testing reasons. i tested and the changes took over the entire page in contrast to just appearing in the content area. I actually just wanted to load a form that is created in another asp. page into the main content area... I seriously need help with this... Every little help, detail and information is dearly appreciated... thanks so much in advance

  • How can I create an http handler to redirect all traffic to HTML pages?

    - by Eitan
    Our company would like to redirect all calls to html files on our server to a separate page. The html pages are NOT in an asp.net application. In order to do this, I've been writing and IIS Handler in asp.net. 1) Is this possible to add an IIS handler to redirect static content that isn't served by any asp.net engine, i.e. stand alone files on the server? 2) If it is possible, how do I do this? I created an http handler in a class library. In the app.config I added the handler to the and sections. I added the DLL to the GAC, I changed the html mapping to my custom IIS dll and nothing works. Is there a tutorial or explanation from A to B on how to do this? Thanks. E p.s. I'm using IIS 7.5

  • Shouldn’t GridView’s RowStyle-HorizontalAlign property overwrite CSS’s text-align property?

    - by AspOnMyNet
    a) As far as I know, GridView’s RowStyle-HorizontalAlign property should overwrite CSS’s text-align property, and thus text inside GridView's cells should be located on the left side of the cells, but is instead moved to the right side. Why is that? b) Similarly, RowStyle-Font-Bold should overwrite CSS’s font-weight property and thus fonts shouldn’t be in bold. But again, CSS’s property overwrites RowStyle’s Font-Bold property. Why? <div id="someClass"> <asp:GridView ID="gvwShowUsers" runat="server" > <RowStyle BackColor="#FFFBD6" ForeColor="#333333" Font-Bold="false" HorizontalAlign="Left" /> <Columns> <asp:BoundField DataField="UserName" HeaderText="UserName" /> </Columns> </asp:GridView> </div> CSS file: #someClass td { font-weight:bolder; text-align:right; } thanx

  • Problem with passing folder path string to web service function via jQuery.ajax

    - by the_V
    Hello, I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file): var d = "{'str':'<%=System.DateTime.Now.ToString() %>', 'applicationPath':'<%=GetApplicationPath() %>'}"; $.ajax({ type: "POST", url: "http://localhost/testwebsite/TestWebService.asmx/Test", data: d, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status, error) { var err = eval("(" + xhr.responseText + ")"); alert(err.Message); }, success: function (msg) { } }); That's what GetApplicationPath method looks like: protected string GetApplicationPath() { return HttpUtility.HtmlEncode(Request.PhysicalApplicationPath); } And here is a header of web-service function which I'm trying to call: public void Test(string str, string applicationPath) Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:\Projects\Samples\mytestwebsite\'". How can I overcome this?

  • Emit Knowledge - social network for knowledge sharing

    - by hajan
    Emit Knowledge, as the words refer - it's a social network for emitting / sharing knowledge from users by users. Those who can benefit the most out of this network is perhaps all of YOU who have something to share with others and contribute to the knowledge world. I've been closely communicating with the core team of this very, very interesting, brand new social network (with specific purpose!) about the concept, idea and the vision they have for their product and I can say with a lot of confidence that this network has real potential to become something from which we will all benefit. I won't speak much about that and would prefer to give you link and try it yourself - http://www.emitknowledge.com Mainly, through the past few months I've been testing this network and it is getting improved all the time. The user experience is great, you can easily find out what you need and it follows some known patterns that are common for all social networks. They have some real good ideas and plans that are already under development for the next updates of their product. You can do micro blogging or you can do regular normal blogging… it’s up to you, and the way it works, it is seamless. Here is a short Question and Answers (QA) interview I made with the lead of the team, Marijan Nikolovski: 1. Can you please explain us briefly, what is Emit Knowledge? Emit Knowledge is a brand new knowledge based social network, delivering quality content from users to users. We believe that people’s knowledge, experience and professional thoughts compose quality content, worth sharing among millions around the world. Therefore, we created the platform that matches people’s need to share and gain knowledge in the most suitable and comfortable way. Easy to work with, Emit Knowledge lets you to smoothly craft and emit knowledge around the globe. 2. How 'old' is Emit Knowledge? In hamster’s years we are almost five years old start-up :). Just kidding. We’ve released our public beta about three months ago. Our official release date is 27 of June 2012. 3. How did you come up with this idea? Everything started from a simple idea to solve a complex problem. We’ve seen that the social web has become polluted with data and is on the right track to lose its base principles – socialization and common cause. That was our start point. We’ve gathered the team, drew some sketches and started to mind map the idea. After several idea refactoring’s Emit Knowledge was born. 4. Is there any competition out there in the market? Currently we don't have any competitors that share the same cause. What makes our platform different is the ideology that our product promotes and the functionalities that our platform offers for easy socialization based on interests and knowledge sharing. 5. What are the main technologies used to build Emit Knowledge? Emit Knowledge was built on a heterogeneous pallet of technologies. Currently, we have four of separation: UI – Built on ASP.NET MVC3 and Knockout.js; Messaging infrastructure – Build on top of RabbitMQ; Background services – Our in-house solution for job distribution, orchestration and processing; Data storage – Build on top of MongoDB; What are the main reasons you've chosen ASP.NET MVC? Since all of our team members are .NET engineers, the decision was very natural. ASP.NET MVC is the only Microsoft web stack that sticks to the HTTP behavioral standards. It is easy to work with, have a tiny learning curve and everyone who is familiar with the HTTP will understand its architecture and convention without any difficulties. 6.

It is easy to work with, have a tiny learning curve and everyone who is familiar with the HTTP will understand its architecture and convention without any difficulties. 7. Did you use some of the latest Microsoft technologies? If yes, which ones? Yes, we like to rock the cutting edge tech house. Currently we are using Microsoft’s latest technologies like ASP.NET MVC, Web API (work in progress) and the best for the last; we are utilizing Windows Azure IaaS to the bone. 8. Can you please tell us shortly, what would be the benefit of regular bloggers in other blogging platforms to join Emit Knowledge? Well, unless you are some of the smoking ace gurus whose blogs are followed by a large number of users, our platform offers knowledge based segregated community equipped with tools that will enable both current and future users to expand their relations and to self-promote in the community based on their activity and knowledge sharing. 10. I see you are working very intensively and there is already integration with some third-party services to make the process of sharing and emitting knowledge easier, which services did you integrate until now and what do you plan do to next? We have “reemit” functionality for internal sharing and we also support external services like: Twitter; LinkedIn; Facebook; For the regular bloggers we have an extra cream, Windows Live Writer support for easy blog posts emitting. 11. What should we expect next? Currently, we are working on a new fancy community feature. This means that we are going to support user groups to be formed. So for all existing communities and user groups out there, wait us a little bit, we are coming for rescue :). One of the top next features they are developing is the Community Feature. It means, if you have your own User Group, Community Group or any other Group on which you and your users are mostly blogging or sharing (emitting) knowledge in various ways, Emit Knowledge as a platform will help you have everything you need to promote your group, make new followers and host all the necessary stuff that you have had need of. I would invite you to try the network and start sharing knowledge in a way that will help you gather new followers and spread your knowledge faster, easier and in a more efficient way! Let’s Emit Knowledge!

  • Using nested Master Pages

    Hi. I'm very new to ASP.NET, help me please understand MasterPages conception more. I have Site.master with common header data (css, meta, etc), center form (blank) and footer (copyright info, contact us link, etc). <%@ Master Language="C#" AutoEventWireup="true" CodeFile="Site.master.cs" Inherits="_SiteMaster" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="tagHead" runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" href="styles.css" type="text/css" /> </head> <body> <form id="frmMaster" runat="server"> <div> <asp:ContentPlaceHolder ID="holderForm" runat="server"></asp:ContentPlaceHolder> <asp:ContentPlaceHolder ID="holderFooter" runat="server">Some footer here</asp:ContentPlaceHolder> </div> </form> </body> </html> and I want to use second master page for a project into sub directory, which would contains SQL query on Page_Load for logging (it isn't necessary for whole site). <%@ Master Language="C#" AutoEventWireup="true" CodeFile="Project.master.cs" Inherits="_ProjectMaster" MasterPageFile="~/Site.master" %> <asp:Content ContentPlaceHolderID="holderForm" runat="server"> <asp:ContentPlaceHolder ID="holderForm" runat="server" EnableViewState="true"></asp:ContentPlaceHolder> </asp:Content> <asp:Content ContentPlaceHolderID="holderFooter" runat="server"> <asp:ContentPlaceHolder ID="holderFooter" runat="server" EnableViewState="true"></asp:ContentPlaceHolder> </asp:Content> But I have a problem: footer isn't displayed. Where is my mistake? Am I right to use second master page as super class for logging? Project page looks like this: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MasterPageFile="~/Project.master" %> <asp:Content ContentPlaceHolderID="holderForm" runat="server"> <p>Hello World!</p> </asp:Content> <asp:Content ContentPlaceHolderID="holderFooter" runat="Server"> Some footer content </asp:Content>

    Hey all, i have this peice of code that allows a user to select a jpg image, resize it and uploads it to the server driectory. The problem being is that it reloads the aspx page when it saves the image. My question is-is there any way to do this same thing but with ajax so that it doesn't leave the page after submitting it? I've done this pleanty of times with classic asp pages but never with a aspx page. Here is the code for the ASPX page: <%@ Page Trace="False" Language="vb" aspcompat="false" debug="true" validateRequest="false"%> <%@ Import Namespace=System.Drawing %> <%@ Import Namespace=System.Drawing.Imaging %> <%@ Import Namespace=System.Drawing.Text %> <%@ Import Namespace=System %> <%@ Import Namespace=System.IO %> <%@ Import Namespace=System.Web %> <%@ Import Namespace=System.ServiceProcess %> <%@ Import Namespace=Microsoft.Data.Odbc %> <%@ Import Namespace=System.Data.Odbc %> <%@ Import Namespace=MySql.Data.MySqlClient %> <%@ Import Namespace=MySql.Data %> <%@ Import Namespace=System.Drawing.Drawing2D %> <%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.Data.ADO" %> <%@ Import Namespace=ADODB %> <SCRIPT LANGUAGE="VBScript" runat="server"> const Lx = 200 const Ly = 60 const upload_dir = "/img/avatar/" const upload_original = "tmpAvatar" const upload_thumb = "thumb" const upload_max_size = 256 dim fileExt dim newWidth, newHeight as integer dim l2 dim fileFld as HTTPPostedFile Dim originalimg As System.Drawing.Image dim msg dim upload_ok as boolean </script> <% Dim theID, theEmail, maleOrFemale theID = Request.QueryString("ID") theEmail = Request.QueryString("eMail") maleOrFemale = Request.QueryString("MF") randomize() upload_ok = false if lcase(Request.ServerVariables("REQUEST_METHOD"))="post" then fileFld = request.files(0) if fileFld.ContentLength > upload_max_size * 1024 then msg = "Sorry, the image must be less than " & upload_max_size & "Kb" else try fileExt = System.IO.Path.GetExtension(fileFld.FileName).ToLower() if fileExt = ".jpg" then originalImg = System.Drawing.Image.FromStream(fileFld.InputStream) if originalImg.Height > Ly then newWidth = Ly * (originalImg.Width / originalImg.Height) newHeight = Ly end if Dim thumb As New Bitmap(newWidth, newHeight) Dim gr_dest As Graphics = Graphics.FromImage(thumb) dim sb = new SolidBrush(System.Drawing.Color.White) gr_dest.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality gr_dest.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality gr_dest.FillRectangle(sb, 0, 0, thumb.Width, thumb.Height) gr_dest.DrawImage(originalImg, 0, 0, thumb.Width, thumb.Height) try originalImg.save(Server.MapPath(upload_dir & upload_original & fileExt), originalImg.rawformat) thumb.save(Server.MapPath(upload_dir & theID & fileExt), originalImg.rawformat) msg = "Uploaded " & fileFld.FileName & " to " & Server.MapPath(upload_dir & upload_original & fileExt) upload_ok = true File.Delete(Server.MapPath(upload_dir & upload_original & fileExt)) catch msg = "Sorry, there was a problem saving your avatar.

  • Strange intermittent SQL connection error, fixes on reboot, comes back after 3-5 days (ASP.NET)

    - by Ryan
    For some reason every 3-5 days our web app loses the ability to open a connection to the db with the following error, the strange thing is that all we have to do is reboot the container (it is a VPS) and it is restored to normal functionality. Then a few days later or so it happens again. Has anyone ever had such a problem? I have noticed a lot of ANONYMOUS LOGONs in the security log in the middle of the night from our AD server which is strange, and also some from an IP in Amsterdam.

  • ASP.NET MVC RememberMe(It's large, please don't quit reading. Have explained the problem in detail a

    - by nccsbim071
    After searching a lot i did not get any answers and finally i had to get back to you. Below i am explaining my problem in detail. It's too long, so please don't quit reading. I have explained my problem in simple language. I have been developing an asp.net mvc project. I am using standard ASP.NET roles and membership. Everything is working fine but the remember me functionality doesn't work at all. I am listing all the details of work. Hope you guys can help me out solve this problem. I simply need this: I need user to login to web application. During login they can either login with remember me or without it. If user logs in with remember me, i want browser to remember them for long time, let's say atleast one year or considerably long time. The way they do it in www.dotnetspider.com,www.codeproject.com,www.daniweb.com and many other sites. If user logs in without remember me, then browser should allow access to website for some 20 -30 minutes and after that their session should expire. Their session should also expire when user logs in and shuts down the browser without logging out. Note: I have succesfully implemented above functionality without using standard asp.net roles and membership by creating my own talbes for user and authenticating against my database table, setting cookie and sessions in my other projects. But for this project we starting from the beginning used standard asp.net roles and membership. We thought it will work and after everything was build at the time of testing it just didn't work. and now we cannot replace the existing functionality with standard asp.net roles and membership with my own custom user tables and all the stuff, you understand what i am taling about. Either there is some kind of bug with standard asp.net roles and membership functionality or i have the whole concept of standard asp.net roles and membership wrong. i have stated what i want above. I think it's very simple and reasonable. What i did Login form with username,password and remember me field. My setting in web.config: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880"/> </authentication> in My controller action, i have this: FormsAuth.SignIn(userName, rememberMe); public void SignIn(string userName, bool createPersistentCookie) { FormsAuthentication.SetAuthCookie(userName, createPersistentCookie); } Now the problems are following: I have already stated in above section "I simply need this". user can successfully log in to the system. Their session exists for as much minutes as specified in timeout value in web.config. I have also given a sample of my web.config. In my samplem if i set the timeout to 5 minutes,then user session expires after 5 minutes, that's ok. But if user closes the browser and reopen the browser, user can still enter the website without loggin in untill time specified in "timeout" has not passed out. The sliding expiration for timeout value is also working fine. Now if user logs in to the system with remember me checked, user session still expires after 5 minutes. This is not good behaviour, is it?. I mean to say that if user logs in to the system with remember me checked he should be remembered for a long time untill he doesn't logs out of the system or user doesn't manually deletes all the cookies from the browser. If user logs in to the system without remember me checked his session should expire after the timeout period values specified in web.config and also if users closes the browser. The problem is that if user closes the browser and reopens it he can still enter the website without logging in. I search internet a lot on this topic, but i could not get the solution. In the blog post(http://weblogs.asp.net/scottgu/archive/2005/11/08/430011.aspx) made by Scott Gu on exactly the same topic. The users are complaining about the same thing in their comments ut there is no easy solution given in by Mr. Scott. I read it at following places: http://weblogs.asp.net/scottgu/archive/2005/11/08/430011.aspx http://geekswithblogs.net/vivek/archive/2006/09/14/91191.aspx I guess this is a problem of lot's of users. As seem from blog post made by Mr. Scott Gu. Your help will be really appreciated. Thanks in advance.

  • ContentPlaceHolders: Repeated Content

    - by brad
    Scenario I have an application using asp.net Master Pages in which I would like to repeat some content at the top and bottom of a page. Currently i use something like this: Master Page <html> <body> <asp:ContentPlaceHolder ID="Foo" runat="server"> </asp:ContentPlaceHolder> <!-- page content --> <asp:ContentPlaceHolder ID="Bar" runat="server"> </asp:ContentPlaceHolder> </body> </html> Content Page <asp:Content ID="Top" ContentPlaceHolderID="Foo" runat="server"> <!-- content --> </asp:Content> <asp:Content ID="Bottom" ContentPlaceHolderID="Bar" runat="server"> <!-- content repeated --> </asp:Content> Maintenance As you know, repeating things in code is usually not good. It creates maintenance problems. The following is what I would like to do but will obviously not work because of the repeated id attribute: Master Page <html> <body> <asp:ContentPlaceHolder ID="Foo" runat="server"> </asp:ContentPlaceHolder> <!-- page content --> <asp:ContentPlaceHolder ID="Foo" runat="server"> </asp:ContentPlaceHolder> </body> </html> Content Page <asp:Content ID="Top" ContentPlaceHolderID="Foo" runat="server"> <!-- content (no repetition) --> </asp:Content> Possible? Is there a way to do this using asp.net webforms? The solution does not necessarily have to resemble the above content, it just needs to work the same way. Notes I am using asp.net 3.0 in Visual Studio 2008

  • How to hide jQuery Sub-Menus(ddsmoothmenu)?

    - by Tim
    I'm new to jQuery and i must admit that i've understood nothing yet, the syntax appears to me as an unknown language although i thought that i had my experiences with javascript. Nevertheless i managed it to implement this menu in my asp.net masterpage's header. Even got it to work that the content-page is loaded with ajax with help from here. But finally i'm failing with the menu to disappear when the new page was loaded asynchronously. I dont know how to hide this accursed jQuery Menu. Following the part of the js-file where the events are registered for hiding/disappearing. I dont know how to get the part that is responsible for it and even i dont know how to implement that part in my Anchor-onclick function where i dont have a reference to the jQuery Object. buildmenu:function($, setting){ var smoothmenu=ddsmoothmenu var $mainmenu=$("#"+setting.mainmenuid+">ul") //reference main menu UL $mainmenu.parent().get(0).className=setting.classname || "ddsmoothmenu" var $headers=$mainmenu.find("ul").parent() $headers.hover( function(e){ $(this).children('a:eq(0)').addClass('selected') }, function(e){ $(this).children('a:eq(0)').removeClass('selected') } ) $headers.each(function(i){ //loop through each LI header var $curobj=$(this).css({zIndex: 100-i}) //reference current LI header var $subul=$(this).find('ul:eq(0)').css({display:'block'}) $subul.data('timers', {}) this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$subul.outerWidth(), subulh:$subul.outerHeight()} this.istopheader=$curobj.parents("ul").length==1? true : false //is top level header? $subul.css({top:this.istopheader && setting.orientation!='v'? this._dimensions.h+"px" : 0}) $curobj.children("a:eq(0)").css(this.istopheader? {paddingRight: smoothmenu.arrowimages.down[2]} : {}).append( //add arrow images '<img src="'+ (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[1] : smoothmenu.arrowimages.right[1]) +'" class="' + (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[0] : smoothmenu.arrowimages.right[0]) + '" style="border:0;" />' ) if (smoothmenu.shadow.enable){ this._shadowoffset={x:(this.istopheader?$subul.offset().left+smoothmenu.shadow.offsetx : this._dimensions.w), y:(this.istopheader? $subul.offset().top+smoothmenu.shadow.offsety : $curobj.position().top)} //store this shadow's offsets if (this.istopheader) $parentshadow=$(document.body) else{ var $parentLi=$curobj.parents("li:eq(0)") $parentshadow=$parentLi.get(0).$shadow } this.$shadow=$('<div class="ddshadow'+(this.istopheader? ' toplevelshadow' : '')+'"></div>').prependTo($parentshadow).css({left:this._shadowoffset.x+'px', top:this._shadowoffset.y+'px'}) //insert shadow DIV and set it to parent node for the next shadow div } $curobj.hover( function(e){ var $targetul=$subul //reference UL to reveal var header=$curobj.get(0) //reference header LI as DOM object clearTimeout($targetul.data('timers').hidetimer) $targetul.data('timers').showtimer=setTimeout(function(){ header._offsets={left:$curobj.offset().left, top:$curobj.offset().top} var menuleft=header.istopheader && setting.orientation!='v'? 0 : header._dimensions.w menuleft=(header._offsets.left+menuleft+header._dimensions.subulw>$(window).width())? (header.istopheader && setting.orientation!='v'? -header._dimensions.subulw+header._dimensions.w : -header._dimensions.w) : menuleft //calculate this sub menu's offsets from its parent if ($targetul.queue().length<=1){ //if 1 or less queued animations $targetul.css({left:menuleft+"px", width:header._dimensions.subulw+'px'}).animate({height:'show',opacity:'show'}, ddsmoothmenu.transition.overtime) if (smoothmenu.shadow.enable){ var shadowleft=header.istopheader? $targetul.offset().left+ddsmoothmenu.shadow.offsetx : menuleft var shadowtop=header.istopheader?$targetul.offset().top+smoothmenu.shadow.offsety : header._shadowoffset.y if (!header.istopheader && ddsmoothmenu.detectwebkit){ //in WebKit browsers, restore shadow's opacity to full header.$shadow.css({opacity:1}) } header.$shadow.css({overflow:'', width:header._dimensions.subulw+'px', left:shadowleft+'px', top:shadowtop+'px'}).animate({height:header._dimensions.subulh+'px'}, ddsmoothmenu.transition.overtime) } } }, ddsmoothmenu.showhidedelay.showdelay) }, function(e){ var $targetul=$subul var header=$curobj.get(0) clearTimeout($targetul.data('timers').showtimer) $targetul.data('timers').hidetimer=setTimeout(function(){ $targetul.animate({height:'hide', opacity:'hide'}, ddsmoothmenu.transition.outtime) if (smoothmenu.shadow.enable){ if (ddsmoothmenu.detectwebkit){ //in WebKit browsers, set first child shadow's opacity to 0, as "overflow:hidden" doesn't work in them header.$shadow.children('div:eq(0)').css({opacity:0}) } header.$shadow.css({overflow:'hidden'}).animate({height:0}, ddsmoothmenu.transition.outtime) } }, ddsmoothmenu.showhidedelay.hidedelay) } ) //end hover }) //end $headers.each() $mainmenu.find("ul").css({display:'none', visibility:'visible'}) } one link of my menu what i want to hide when the content is redirected to another page(i need "closeMenu-function"): <li><a href="DeliveryControl.aspx" onclick="AjaxContent.getContent(this.href);closeMenu();return false;">Delivery Control</a></li> In short: I want to fade out the submenus the same way they do automatically onblur, so that only the headermenu stays visible but i dont know how. Thanks, Tim EDIT: thanks to Starx' private-lesson in jQuery for beginners i solved it: I forgot the # in $("#smoothmenu1"). After that it was not difficult to find and call the hover-function from the menu's headers to let them fade out smoothly: $("#smoothmenu1").find("ul").hover(); Regards, Tim
