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 am getting two identical errors message when I view my Web page in my browser:
Valid User Session Variable Not Found: System.NullReferenceException for this line:
Code:
Response.Write(Session("ValidUser").ToString & "<br />") <----------
and the same error for this line:
Code:
Response.Write(Session("strEmail").ToString) <-----------
This is the code in that page:
Code:
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
Try
Response.Write(Session("ValidUser").ToString & "<br />")
Catch ex As System.Exception
Response.Write("Valid User Session Variable Not Found: " & ex.ToString & "<br />")
End Try
[Code] .....
This the page that users are redirected to after logging on and, after verifying their credentials at the log-on stage, should show 'Hello DonaldDuck@Disney.com, Welcome to my website'.
Do these errors mean that the user cannot be validated in the database?

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'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 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::
[Code]....
If the target control's invisible, I get error "Error: 'null' is null or not an object" since the control's not rendered.

In my asp.net4.0 page, I have 3 Images each embedded in LinkButton :
<asp:LinkButton ID="panImgLnkBtn" runat="server">
<asp:Image runat="server" ID="panImg" BorderStyle="Ridge" BorderColor="Turquoise"
Width="130px" Height="100px" ImageUrl="~/CRMImages/no_image_symbol.png" />
</asp:LinkButton>
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.
