I have extended a gridview to add an additional header with following two hyperlink controls "Select All" and "Clear All". These will operate on checkboxes in the data rows of the grid. I hide the column headers as I only want to show one column with checkboxes and "Select/Clear All" links. Everything is working as expected. Now, I wanted to add a scrollbar to my grid control, I did add the scroll bar using div but what it does is, it includes the "Select All and Clear All" links aswell. I only need to add the scrollbar to datarows and not to the header.I am trying to extend my control to include hte scrollbar by adding div during Render function. But how will I determine or loop through header rows? How will i get the header row with hyperlinks that I created above?? In Render if I do this.HeaderRow, it gets the original column header and not the custom header.
I'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.
I have several checkbox controls on my web form that are not server controls (runat="server") How can I access these controls form my C# code? Can this be done with document.GetelementById from the server side using C#? Or some other technique?

I currently facing a cascading drop down list problem. When I develop my website at local pc, everything work just fine. However I deploy it to server, I get Method Error 500.
I have a tricky problem. I am in a situation where I need to use a method defined in a .cs file from a javascript function. The problem is we are using .NET 1.1 and AJAX cannot be used for the application.
Also, I will need to pass a string from the javascript to the server side method. The page where I am implementing the javascript is a .as
I have tried doing a post back and creating a RaisePostBack event handler method (both in the .aspx page and the .ascx user control) but no luck.
The javascript is called from a span's onclick event. The javascript function's input parameter would be a string which I will need to use to instantiate an Attachment.
I created a method which instantiates an Attachment using a string and calls the corresponding Delete() method for the Attachment object.
Now, I will need to pass the string from javascript function to the method I have created. I cannot use PageMethods.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomPanel.ascx.cs" CodeFile="CustomPanel.ascx.cs" CodeFileBaseClass="System.Web.UI.WebControls.Panel" Inherits="MyProject.CustomPanel" %> ... namespace MyProject { public partial class CustomPanel : System.Web.UI.WebControls.Panel { ... } }
However, I'm really not sure how to proceed from here, because this does not appear to follow a logical inheritance path that includes System.Web.UI.UserControl / Am I doing something wrong? How can I inherit Panel and extend standard event-handlers, such as PreInit?
MSDN documentation says that the ScriptManager class is part of the System.Web.UI namespace and I see that I can create a ScriptManager object programmatically. However, I don't see the ScriptManager control on the front-end. Do I need to reference the Ajax Control Toolkit dll in order to have access to control?
I need to make an ajax call from my javascript and access a control on my page. Using a webmethod wont work then since it's static, do I have any other options?
