AJAX Gridview Modal popup

[btreddy]

Hii experts,

Im tring to display a panel as a modal popup when i click a link button which is placed in the footer template of my Grid view.But its not getting compiled and the error its showing is

"The TargetControlID of 'mpeAddParticipant' is not valid. A control with ID 'ParticipantMeetingID' could not be found"'mpeAddParticipant' is the id of the modal pop up extender and 'ParticipantMeetingID' is the id of the link button which ic placed in the footer template of the grid view.

i tried of giving any other control which is out side of grid view thn its working fine...

Plz suggest me the solution...

Thanks in advance..

I think this is a limitation on how the Modal Popup control works.
The control can only work with controls that are on the page, not within another control.

1. Put the ModalPopupExtender in the cell together with your LinkButton.

OR

2. Dynamically assign TargetControlID on Page_Load. E.g.

if (!Page.IsPostBack)
{
   ModalPopupExtender1.TargetControlID =
      GridView1.FooterRow.FindControl("LinkButton1").UniqueID;
}
