A page could have an attribute MasterType to make Page.Master to be strong-typed:
<%@ MasterType VirtualPath="~/Site.master" %>
If all my pages inherits specific class inherited System.Web.UI.Page itself, can I someway get access to this.Master property in it so I could call master page's methods?
The docs for @MasterType have this example.
<%@ Page masterPageFile="~/MasterPage.master"%>
<%@ MasterType virtualPath="~/MasterPage.master"%>
Why is @MasterType even needed? Couldn't the compiler automatically take the same actions based solely on @Page masterPageFile? When would you not want to use both?
I'm trying to use a MasterType TypeName to access a class with master pages. This works when I'm using .NET 2.0, VS 2005, and C#. When I try this using .NET 3.5, VS 2008 and C# I get the error:
The type or namespace name 'classA' could not be found (are you missing a using directive or an assembly reference?) and it is pointing to the Default.aspx.designer.cs
In the default.aspx I have:
<%@ Page Language="C#" MasterPageFile="...
<%@ MasterType TypeName="classA" %>
I have added a folder App_Code to my project and in that folder I have a class file "classA.cs" that contains:
Using ...
Namespace Project.App_Code
{
public class classA : System.Web.UI.MasterPage
...
The main difference that I see from where it works and where it doesn't work is that where it doesn't work it uses the namespace called Project.So I figure my problem is in the including the class classA in the namespace or properly including the namespace and / or App_Code directory in the MasterType TypeName which I don't seem to be able to figure out.

View 11 RepliesI am trying to write a quote generator. For each product, there are a set of options. I want to dynamically add a drop down list for each option, and then have their SelectedIndexChanged events all wired up to update the quote cost.
I am not having any trouble adding the DropDownList controls to my UpdatePanel, but I can't seem to wire up the events.
After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this:
Edit: Since programmatically adding AsyncPostBackTrigger controls is not supported, I've change my code to this, but I still don't get the event:
Edit 2: Tried adding a PlaceHolder to add the drop down lists to (instead directly into the ContentTemplateContainer, still no events firing.

I want to add StyleSheets programmatically in the head section but one of the examples I saw seemed to need to many lines of code to add just one style sheet even though I may need a lot: Example Code:
HtmlLink css = new HtmlLink();
css.Href = "css/fancyforms.css";
css.Attributes["rel"] = "stylesheet";
css.Attributes["type"] = "text/css";
css.Attributes["media"] = "all";
Page.Header.Controls.Add(css);
I also use Page.Header.RenderControl() method but it didn't work either. Object null something error was thrown. I also used Page.Header.InnerHtml and InnerText += "<link .... "/> things but they threw the Literal error which is I think common error. I used this code :
List<Literal> cssFiles = new List<Literal>();
cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainDesign.css") + @""" type=""text/css"" rel=""stylesheet"" />" });
cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainLayout.css") + @""" type=""text/css"" rel=""stylesheet"" />" });
AddStyleRange(cssFiles);
private void AddStyleRange(List<Literal> cssFiles)
{
foreach (Literal item in cssFiles)
{
this.Header.Controls.Add(item);
}
}
It worked at first but when I change the pages it stopped working. I am using Master Page and I am writing these codes on Master.cs file and also some people recommended to use this.Header instead of Page.Header but when I built it throws an error which says I cannot declare that like this. It shouldn't be that hard to add many styles.

how to trigger the Select() method.
Here's the scenario: ASP.NET 3.5 C# app connecting to an MS SQL backend. I created a LINQ to SQL class called test.dbml and dragged a table called tblTest to the design surface. The table has two columns: the primary key is Email and the other column is Name. Then I dropped a LinqDataSource on the page. The LinqDataSource is not connected to a databound control. It will only being used to retrieve the name associated with a supplied email address. In the Page_Load event, I feed the Where clause:
[Code]....
However, I put a breakpoint inside the ldsAdmin_Selected event and it never hits. With an ObjectDataSource, you can use odsAdmin.Select(); to trigger the ObjectDataSource to actually run and return the info. What's the equivalent method of triggering a LinqDataSource?
I can check the value of a checkbox in a GridViewRow:
isChecked = CType(row.FindControl("chkSelect"), CheckBox).Checked
But what's baking my noodle is trying to figure out how to programmatically set a checkbox to checked.
The scenario is I have some rows in a GridView that are associated to another value in a dropdown. So, when I select the value in the dropdown, I'd like the checkboxes in the GridViewRows that are associated with that value to be already checked.
Problem: The check value is not persisted in the database. There's no field for it. The checkbox on the GridViewRows is an ASP TemplateField.
So I iterate through the rows and would like to check whichever checkboxes I need to based on whatever condition.

Now from the code behind I want to change the ID of the button

But it is now working. Is it possible at the first place?
EDIT
I've created the control in the HTML mark up and not through code.
As the title says. What could be amiss?
I have a regular TextBox on my page - <asp:TextBox ID="tb" runat="server" />

RequiredFieldValidator rfv = new RequiredFieldValidator();
rfv.ID = "rfv";
rfv.ControlToValidate = tb.ID;
rfv.ErrorMessage = "error";

I want to be able to add the same Usercontrol by code more than once, when I click a button.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Panel2.Controls.Add(MyStatus)

the problem is that the usercontrol is only added once
