Let server-side postback close popup on cross click

[Erik]

Hi,

I try to execute some server-side code when the cross is clicked. This code needs to deside if the window can be closed or not. I used this code for it:

OnClientBeforeClose = "function(s, e) {e.set_cancel(true);__doPostBack('" + UniqueID + "', '" + CloseDialog + "');}";

Inside the raisePostBack method I call "window.close()" client-sided if my code want the window to close.

I used parts of this sample to make this, but this is totaly handled client-side:
http://www.telerik.com/community/code-library/aspnet-ajax/window/confirm-closing-of-a-radwindow-by-using-radconfirm.aspx

My problem is that when I call the "window.close()" method client-sided the onClientBeforeClose method is executed first again and will stop the close action of the window.

Any suggestion how I can solve this problem?

Thanks!
Erik

Hello Erik,

You can use a flag to determine whether you should cancel the event:

var shouldCancel = true;
function OnClientBeforeClose(sender, args)
{
    if (shouldCancel)
    {
        args.set_cancel(true);
        $find("<%=RadAjaxManager1.ClientID %>").ajaxRequest("CheckRadWindow");
    }
    shouldCancel = true;
}

and inject a script that will close the RadWindow from the code-behind (and reduce the flag to false, of course).

I am also attaching a simple page that shows this in action to the thread. It uses a session variable to simulate your logic and odd clicks close the RadWindow, even - do not: http://screencast.com/t/GY0hRcMNfH. I am also using the RadAjaxManager for ease of demonstration, yet this approach should also work with your AJAX calls.
