[Solved] Prevent window from Closing in onClose client event

[Kapil]

Hello Everyone,

I am trying to display a confirm dialog when a user tries to close a window by click the 'X' in the top right corner. If the user goes for 'OK' option,  I would like to continue closing the window but if the user presses the 'Cancel' button I would like to prevent the window from closing. Is there a way to do that?

Thanks.

Update: I looked at the window client events on : http://demos.telerik.com/aspnet-mvc/window/clientsideevents. It says that the onClose event is cancellable but nowhere can I see how to cancel the event.

Does nobody know how to solve this problem??

Does no telerik admin know the solution to this??

I was able to figure out the solution to my problem on my own. if you do

e.preventDefualt();

in the onClose event it would prevent the window from closing. There is a mention in the documentation that the onClose event is cancellable but nowhere does it say how to cancel the onclose event.
