I have a user control that contains the Modal Popup control.

I would like to set the Target Control Id of the ModalPopupExtender to be a control that is located on a different page.

For example I have my master page and I need to include the user control. But i want a button that is on the Master Page to be the TargetControlId.

 The problem Im having is that If I include the control that initiates the extender into the usercontrol, then when that user control is placed on the Master Page, its inherating all the Styles of the <div> on the master page its being placed in which is a problem.

What i would like to do is create the user control and then include it in the master page outside of the main content area but then put a image button with in the header which would then call the extender.

When i do this i get the error:The TargetControlID of 'ModalPopupExtender' is not valid. A control with ID 'ctl00_cmdGetHelp' could not be found.

Master Page: Image button renders with Id of ctl00_cmdGetHelp

UserControl: I set the TargetControlId to : "ctl00_cmdGetHelp"

Again this causes an error.

 Any ideas??

is ctl00_cmdGetHelp the ID or uniqueID. im not sure but it seems like you are setting the target ID to the uniqueID in which case it might not find that control ID because you never initiate the controlID. (i cant remember if you leave ID blank if it automatically becomes the uniqueID) but trying doing:

cmdGetHelp.ID = "cmdGetHelp";

extender.TargetControlID = cmdGetHelp.ID; or extender.TargetControlID = "cmdGetHelp";

cowboy,

Thanks, not sure why i made that so difficult. I could of sworn that I tried what I posted before I posted.
For some reason I was trying to set the UniquieId and not the ID of the control.

This is one of those posts where I posted prematurely. Should of worked on it a bit longer.

Any way, ya it works.

Master page: Image button ID="cmdGetHelp"

UserControl:  ModalPopupextender TargetControlId="cmdGetHelp"

 Thanks

glad to help
