How prevent a RadWindow to close

[Gilbert Figueroa]

Since RadWindow don't have closing event, how I can prevent closing a RadWindow? For instance prevent to close without save something.

Hi Gilbert,

The event you are looking for is called PreviewClosed. The naming convention for WPF is to put "Preview" before the name of the event instead of "ing" at the end as it used to be in WindowsForms.

Hope this information helps.
