Stop RadWindow from closing

[Doug Rutledge]

In my application, I'm using the onbeforeunload event to check for unsaved changes by the user.  This works great for regular forms.  I tried the same approach with pages used as RadWindows, and it kind of works.  If I change a value on the radwindow and click the "x" to close it without saving, the RadWindow closes and then the prompt to save shows up.  Obviously this is too late since the RadWindow is now gone.  I thought about trying to use the OnClientClose event on the RadWindow, but the documentation states that it is called after the window is closed.  Is there a way to to run some javascript when the "x" on the RadWindow is clicked so that I have a chance to stop it and ask the user to save changes?

That looks like it will work, but I'm not quite sure how to call the old_close method if I determine that it is ok to close the window.

Hello Doug,

Here is how to do this:

Telerik.Web.UI.RadWindow.prototype.old_close = Telerik.Web.UI.RadWindow.prototype.close;

Telerik.Web.UI.RadWindow.prototype.close = function(e)
{
     //Override close
     //call the old close method when you need to close the window
     this.old_close(e);
}

I hope this helps.
