I'm trying to use a ModalPopupExtender in a user control, so the TargetControl is on the previous (parent) page. In the PageLoad event of the user control, the following code finds the MPE and the button from the previous page, but I don't understand how to actually assign the button to the MPE as the TargetControlID.

I'm using the AJAX ModalPopupExtender control in order to popup a "Login" panel. My problem is that the TargetControlID property happens to be an ASP.Net Menu Control Item. How do I reference that menu item where it's becomes a valid value for the TargetControlID property?

I wantto show up manually a ModalPopupextender without its TargetControlID assigned to anything.
Thus I dont need a button or linkbutton that triggers to show it up.
I put a hiddenfield and attached it to TargetControlID and I can call ModalPopup manually by its show() method.
so why should I have to assign TargetControlID ? I dont wantto use a useless hiddenfield to attach as its Target.is there any other Ajax Control Modal Window that no need a Target ?
I have a gridview showing list of data . When I select one of the row in the gridview, I would like to get panal (say Panel1) to be popup. I used the Ajax ModalPopupExtender but I don't know what should be the value in TargetControlID ?

I am not using any update panels in my page.
I'm firing the my ModalPopupExtender from a server side button click (bthAuth) and then need to hide that button after my processing is complete. When btnAuth.Visible = False is called it displays the ModalPopupExtender. If I remove this piece of code the window goes away like it should.
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnAuth" BackgroundCssClass="modalBackground" PopupControlID="ModalPanel"> </cc1:ModalPopupExtender>
btnAuth_Click():
bunch of stuff here()
btnAuth.Visible = False -- This is what is causing the ModalPopupExtender to stay displayed.
On Page Load:
btnAuth.OnClientClick = String.Format("fnClickUpdate('{0}','{1}')", btnAuth.UniqueID, "")
Function:
<script type="text/javascript">
function fnClickUpdate(sender, e)
{
__doPostBack(sender,e);
}
</script>

Apparently, I cannot display or hide a Panel through ModalPopupExtender if the TargetControlID is not visible in the webform.
The TargetControl of my ModalPopupExtender is button_displayPanel. But once the panel's shown and closed, I hide button_displayPanel and another button is displayed. I need to be able to open the panel from this 2nd button.
Basically, I need to show the panel through another button since the ModalPopupExtender's TargetControl will not be visible.
I use javascript to show the panel::

If the target control's invisible, I get error "Error: 'null' is null or not an object" since the control's not rendered.
Is there any function to set the TargetControlID of a CalendarExtender from Javascript?
I can do something similar with ASP.NET validators with this built int method:

Is there something similar for the CalendarExtender?
I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

On each image, I want to open a popup with "Download" & "Print" buttons.
I was thinking to create a panel and open a popup on linkbutton click by using ajaxToolkit:ModalPopupExtender . But, I realized that for I will need 3 such panels & ModalPopup's for each image as got to set TargetControlId for each link button.
In my other page, I will have more than 10 images.
What can be the best way to achieve this goal in such way that thru out my app I can call this popup and download or print the image ?

I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.

I have a <div> element in a web page. I've assigned it an "ID" and made it a server-side control by using "runat=server". How do I define that <div> in the code-behind. I'm been looking at the "System.Web.UI.HtmlControls" namespace and not sure what to use. The reason I need to do this is because within this <div> is a "Submit" button which will cause a postback. When I click the submit button the first thing it does is it executes a procedure to perform edit checks on the various textbox controls. If a control is empty, a message pops up. When the user clicks "Ok" for the message, the <div> disappears because when the form loads, the <div> style.display property is set to "none" by default. Basically, all I want is for the <div> not to disappear when the edit checks are performed and a messagebox pops up.

I am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?
