Window does not show after grid item command

[Egbert]

Hi,

I'm using a RadGrid with a delete button.
When clicking the delete button, I like to show a window confirm box.
The box will not be shown when the grid in the AjaxUpdatedControl list.

How can I show the window and keep the RadGrid in the AjaxUpdatedControl list?

Thanks,
Egbert

Hi Egbert,

This is a generic AJAX issues - controls that are not part of the partial postback (the RadWIndow in this case) do not get their properties updated on the client. I advise that you examine this sticky thread on opening a RadWindow from the server without depending on AJAX: http://www.telerik.com/forums/opening-radwindow-from-the-server.

On using a confirm from the server code, I advise you examine this article that explains the scenario's peculiarities and offers examples: http://www.telerik.com/help/aspnet-ajax/window-using-radconfirm-in-server-code.html.
