  • access static class from asp.net form

    - by Eden
    I am using <%# MyFormatClass(Eval("fieldname")) % to display data in a grid view on my page. MyFormatClass works fine, but now I want to move it to a central location that can be used by many pages. When I try to access the class <%# Utils.MyFormatClass(Eval("fieldname")) % it no longer works. Is this something we are allowed to do?

  • ASP.Net MVC Outbound Route Matching Problem When Using ActionLink

    - by Godders
    Hi there, Hoping for some help after reading into MVC routing and not coming up with the answer myself. I have the following routes registered: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( null, "YourFeedback/Article/{resourceId}", new { controller = "YourFeedback", action = "Index", contentTypeId = new Guid(ConfigurationManager.AppSettings["ArticleLibraryId"]) }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have the following ActionLink in an aspx view: <%=Html.ActionLink("Your Feedback", "Article", "YourFeedback", new { resourceId = Model.ContentId.ResourceId }, new { @class = "yourFeedback" })%> My understanding of MVC routing is that this would render a anchor link with href of "/YourFeedback/Article/101" where 101 comes from Model.ContentId.ResourceId. Yet the anchor link href is rendered as "YourFeedback/Article/resourceId=101". Any ideas where I'm going wrong? Thanks in advance.

  • Readonly SiteMapNodes in ASP.Net MVC?

    - by BenN
    I'm using MVCSiteMap as a SiteMapProvider for my MVC site. I have a node set up like so.... <mvcSiteMapNode key="1" title="Product" controller="Product" action="Display" isDynamic="true" dynamicParameters="id"> <mvcSiteMapNode key="11" title="More Details" controller="Product" action="MoreDetails" isDynamic="true" dynamicParameters="id" /> </mvcSiteMapNode> ...Which means I can go to ~/Product/Display/12 and get a correct sitemap node for product id 12 (in this case just Product. And I can go to ~/Product/MoreDetails/12 and get the sitemap path for the MoreDetails (Product - More Details). The problem is that the link back to Product in this sitemap doesn't work - it skips the id off the end, instead linking to ~/Product/Display/. Which sucks. I've discovered I can edit the Title of a node using SiteMap.CurrentNode.Title = "My New Title"; But... SiteMap.CurrentNode.ParentNode.Url = "http://www.google.com"; Doesn't set the Url for the parent node; it gets the default link described before. Any ideas how I can set the URL of a SiteMapNode?

  • ASP.NET MVC grid/table

    - by nivlam
    public class Person { public string First { get; set; } public string Last { get; set; } public int Age { get; set; } public IEnumerable<Child> Children { get; set; } } public class Child { public string First { get; set; } public string Last { get; set; } public int Age { get; set; } } I'm searching for a way to render a table from my model, which is of type IEnumerable<Person>. I'm trying to generate the following table: <table> <tr class="person"> <td>First 1</td> <td>Last 1</td> <td>1</td> </tr> <tr class="child"> <td>First 1</td> <td>Last 1</td> <td>1</td> </tr> <tr class="child"> <td>First 2</td> <td>Last 2</td> <td>2</td> </tr> ... ... </table> Each person is a row and each of their children would be individual rows under the person row. This would repeat for each person in IEnumerable<Person>. Are there any grids or components that generate a table like this? I found MvcContrib's grid component, but it doesn't appear to be able to generate these child rows. Is there a way to extend MvcContrib's grid to do this?

  • ADO.NET parameters from TextBox

    - by Geo Ego
    I'm trying to call a parameterized stored procedure from SQL Server 2005 in my C# Winforms app. I add the parameters from TextBoxeslike so (there are 88 of them): cmd.Parameters.Add("@CustomerName", SqlDbType.VarChar, 100).Value = CustomerName.Text; I get the following exception: "System.InvalidCastException: Failed to convert parameter value from a TextBox to a String. ---> System.InvalidCastException: Object must implement IConvertible." The line throwing the error is when I call the query: cmd.ExecuteNonQuery(); I also tried using the .ToString() method on the TextBoxes, which seemed pointless anyway, and threw the same error. Am I passing the parameters incorrectly?

  • NetworkStream.Read delay .Net

    - by Gilbes
    I have a class that inherits from TcpClient. In that class I have a method to process responses. In that method I call I get the NetworkStream with MyBase.GetStream and call Read on it. This works fine, excpet the first call to read blocks too long. And by too long I mean that the socket has recieved plenty of data, but won't read it until some arbitrary limit is reached. I can see that it has recieved plenty of data using the packet sniffer WireShark. I have set the recieve buffer to small amounts, and very small amounts (like just a few bytes) to no avail. I have done the same with the buffer byte array I pass to the read method, and it still delays. Or to put it another way. I am download 600k. The download takes 5 seconds (at a little over 100k/second connection to the server which makes sense). The initial Read call takes 2-3 seconds and tells me only 256 bytes are availble (256 is the Recieve buffer and the size of the array I read in to). Then magically, the other few hundred thousand bytes can be read in 256 byte chunks in only a few process ticks each. Using a packet sniffer, I know that during those initial 2-3 seconds, the socket has recieved much more than just 256 bytes. My connection wasn't .25k/second for 3 seconds and then 400k for 2 seconds. How do I get the bytes from a socket as they come in?

  • ASP.NET MVC Cookie loses value when page is changed

    - by Jova
    When a user logs in to my site, I create a cookie with some info in it. However, whenever they change page from logging in, the cookie loses it's value. Cookie is still there but it's empty. I've checked my code and the cookie doesn't get rewritten by anything I've done. Does anyone have any idea to why the cookie becomes empty when the page is changed?

  • ASP.NET Webforms site using HTTPCookie with 100 year timeout times out after 20 minutes

    - by Rob
    I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used: // user passed validation FormsAuthentication.Initialize(); // grab the user's roles out of the database String strRole = AssignRoles(UserName.Text); // creates forms auth ticket with expiration date of 100 years from now and make it persistent FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1, UserName.Text, DateTime.Now, DateTime.Now.AddYears(100), true, strRole, FormsAuthentication.FormsCookiePath); // create a cookie and throw the ticket in there, set expiration date to 100 years from now HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) }; // add the cookie to the response queue Response.Cookies.Add(cookie); Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false)); The web.config file auth section looks like this: <authentication mode="Forms"> <forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" /> </authentication> When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008. Any ideas on how to fix this?

  • Check malicious Redirect URL in ASP.NET

    - by acidzombie24
    I heard of sites using other site to redirect users either to their own site or to hide behind another site. In my code i redirect in a few places such as post a comment (its easier to use a return url then figure out the page using data given). How do i check if the return URL is my own url? I think i use absolute paths so i can easily check if the first character is '/' but then i will lose relative flexibility. This also disallows me from doing http://mysite.com/blah in the redirect url. I could patch the url by adding mysite + string but i'll need to figure out if string is a relative url or already a mysite.com url. Whats the easiest way to ensure i am only redirecting to my site?
