  • Accessing Session and IPrinciple data in a Master View in Asp.Net MCV

    - by bplus
    I currently have a abstract controller class that I all my controllers inherit from. In my master page I want to be able to access some data that will be in Session and also the currently user (IPrinciple). I read that I could use the contructor of by abstract base controller class, that is I could do something like public BaseController() { ViewData["SomeData"] = Session["SomeData"]; ViewData["UserName"] = this.User.Identity.Name; } I could then access ViewData["UserName"] etc from my master page. My problem is that both Session and User are null at this point. Does anybody know of a different approach? Thanks in advance.

  • C#: Changing the order of columns when binding DataTable to a GridView

    - by Nir
    How is it possible to change the displayed order of columns from a DataTable? For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this: gridView.DataSource = dt; gridView.DataBind(); But I'd like the GridView to display "b" first (leftmost). Important point: I'm using this to export to Excel and there's no actual output to screen, using: HtmlTextWriter htw = new HtmlTextWriter(sw); gridView.RenderControl(htw); Thanks!

  • Json problem with Page Method call on IE 8.

    - by ProfK
    I have the following code that populates a select element with values from an ajax call, via a Page Method. In FF, the code works perfectly, in IE8 I get the error: 'ResourceList[...].id' is null or not an object. What can I look at here? function readShift(jsonString) { var shiftInfo = Sys.Serialization.JavaScriptSerializer.deserialize(jsonString); var listItems = ""; listItems += "<option value='0'>[Unassigned]</option>"; for (var i = 0; i < shiftInfo.ResourceList.length; i++) { listItems += "<option value='" + shiftInfo.ResourceList[i].id + "'>" + shiftInfo.ResourceList[i].name + "</option>"; } $("#" + resourceListId).html(listItems); };

  • How to get the id of Updatepanel which initiated a postback

    - by Voice
    Hi I need to intercept server callback after udate panel async post back and determine which panel initiated the request. The code is pretty simple: Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(InterceptUpdateCallback); function InterceptUpdateCallback(sender, args) { var updatedPanels = args.get_panelsUpdated(); for (idx = 0; idx < updatedPanels.length; idx++) { if (updatedPanels[idx].id == "myUpdatePanel") { StartSmth(); break; } } } And it works when UpdatePanel is not inside another UpdatePanel. But when it is inside another UpdatePanel updatedPanels[idx].id has parent Updatepanel id. So how can I get the id of UpdatePanel which initiated the request (the inner UpdatePanel)? Thanx

  • 3 websites 1 Project

    - by godz-gift05
    Hey Guys, OK. we are currently on a plan to develop a website for 3 same company. The main difference would be just the look and maybe a couple of extra question for one or two company. Currently each company have their own website and when they required a new function we have to re-code all three website or when one wants a new function just one website update. What we wanna accomplish is to create ONE website that could house all these 3 website. Most of these website function are the same like 90% function is the same I figure out the different look which can be done changing the website style-theme.. But we have problem tackling the functionality of if one company wanted to add something. So if we wanted to update a function we just wanna do a change in one function and that should apply for all.. And if one function is required for one company then just add the new fucntion and assign it to 1 company... How do u structure something like this.. We wanna be able to control what being displayed based on the company and also the fucntions available. THANK YOU. I just need some direction on how to do this, Right now Inheritance is on my head to solve all this problem.

  • Make a final call to the Database when user leaves website (ASPX)?

    - by Jisaak
    I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?

  • implementing security with session variables, how it is insecure

    - by haansi
    I am doing web based projects in dotnet. Currently I am implementing security using session variables. I keep current user id and user type in session and authenticate user from these session variables (say Session["UserId"],Session["UserName"] and Session["UserType"]). Please help me understand how this could be insecure. I've heard that such security can be broken and applications can be hacked very easily, like it is possible to get session id and directly connect to that session id etc. Please guide me on this.

  • varchar data type to datetime data type resulted in an out-of-range??

    - by leen3o
    Very weird problem occurred, I have moved a site from one server to another - All is working, but any query involving a date is playing up. I get the following: DELETE FROM MYTABLE WHERE categoryId = -2 AND datecreated < '3/23/2010'; The conversion of a varchar data type to a datetime data type resulted in an out-of-range value Now what's strange is I have changed the LCID to 1033 on the new server as the date is showing as US format and its still throwing an error! I then tried 2057 and again the same error? Made no difference. I'm a little confused, as this is a working site from a server with IIS6 - The locale is 1033 on that server and it works perfectly!! :S I have just tried thrown a Cdate() around the date too and yet again the same error??? Any ideas??

  • validation controls are not validating on enabling on client side using java script, plz guide

    - by haansi
    Hi, As per requirement I disabled all validation controls in page on PageLoad event in server side. On clicking submit button I want to activate them and validate the page and if the page is ok submit other wise not. I am able to enable all validaters but one thing that I am unable to understand is that they do not validate the page. I set alerts and check they are being enabled but they do not validate the page and let the page submit. I am sorry I couldn't get where I am wrong, may be there need to call some validation method as well or I should prevent default behavior of button. please guide me. Below is my script: <script type="text/javascript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddlEmpStatus.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; if (_selectedIndex == 0) { alert("Nothing selected"); }<br/> else<br/> if (_selectedIndex == 1) { for (i = 0; i < Page_Validators.length; i++) { Page_Validators[i].Enabled = true; } } } </script> thanks in anticipation.

  • Function chaining depending on boolean result

    - by Markive
    This is just an efficiency question really.. I'm interested to know if there is a more efficient or logical way that people use to handle this sort of scenario. In my asp.net application I am running a script to generate a new project my code at the top level looks like this: Dim ok As Boolean = True ok = createFolderStructure() If ok Then ok = createMDB() If ok Then ok = createProjectConfig() If ok Then ok = updateCompanyConfig() I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example). I was just wondering how other people handle this scenario? the vb.net single line if statement is quite succinct but I'm wondering if there is a better way?

  • HttpSessionState Where, How, Advantages?

    - by blgnklc
    You see the code below, how I did use the session variable; So the three questions are; 1- Where are they stored? (Server or Client side) 2- Are they unique for each web page visitor? 3- Can I remove it using ajax or simple js code when my job is done with it? or it will be removed automatically..? sbyte[][] arrImages = svc.getImagesForFields(new String[] { "CustomerName", "CustomerSurName" }); Dictionary<string, byte[]> smartImageData = new Dictionary<string, byte[]>(); int i = 0; foreach (sbyte[] bytes in arrImages) { smartImageData.Add(fieldNames[i], ConvertToByte(bytes)); i++; } Session.Add("SmartImageData", smartImageData);

    - by Bibo
    I found many articles on this but still I don´t know how exactly to do this. I am trying to create my own blog engine, I have View for create article (I am using EF and Code first) and now I must fill number of category in which article should be add but I want to change it to dropdownlist with names of categories. My model looks this: public class Article { public int ArticleID { get; set; } [Required] public string Title { get; set; } [Required] public int CategoryID { get; set; } public DateTime Date { get; set; } [Required()] [DataType(DataType.MultilineText)] [AllowHtml] public string Text { get; set; } public virtual Category Category { get; set; } public IEnumerable<SelectListItem> Categories { get; set; } public virtual ICollection<Comment> Comments { get; set; } } public class Category { public int CategoryID { get; set; } [Required] public string Name { get; set; } public virtual ICollection<Article> Articles { get; set; } } I know I must use Enum (or I think) but I am not exactly sure how. I don´t know which tutorial from that I found is best for me.
