posted

Hello,

I have a popup extender to a panel and an animation progress bar inside.

When I select a row the panel popsup and it seems there is a post back. I removed the extender and still it takes few second to select the row. during this period, the rows disapper from the grid.

What can I do to stop this?

thanks,

Kamal

     Hello,

    This can probably be achieved if you subscribe to some of the client-side events the grid exposes and which are documented here:

    http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR3.5/html/WebGrid_Client_Side_Events_CSOM.html 

    Most of the Before events can be cancelled (see the paragraph on top for information how) - this will prevent the server-side action like postback.

    I see that one of our clients has implemented something similar (show popup window on row click) - you can check it our here:

    Message box in client-side BeforeSelectChangeHandler prevents postback

    And finally, I want to recommend the new WebDialogWindow product that we released recently - it has great popup functionality and looks great. You can view samples of it in our samples framework located here:
