Cancelable OnClose event

I would like to have an event that fires when the user closes the Window and to be able to cancel the event. I would like to have an identifier if the user pressed the "Esc" key or the Close button rendered in the Browser.

At the time of writing, only using the VisibleChanged event can let you prevent the Window from closing. As a workaround, you can cancel this event and use a custom close command that will not trigger it to, effectively, disable closing with Esc: https://blazorrepl.telerik.com/GcaqOxkT13mCiQ4q33.

Hi Daniel,

Thank you for sharing your solution with the community!

Meanwhile, in the admin edit of the opening post I added another option that you and other interested parties may try.

A current workaround, you can have an empty component implement IDisposable within the Window and when the Dispose function is called, trigger a callback passed in as a parameter to the component.
