How can I implement a notification or warning message in Wisej when a user attempts to close the browser or tab?

Hi Nhan,

We also have Application.EnableUnloadConfirmation that you can use.

Hi Nhan,

You can call this in Program.cs:

Application.Eval(@”window.addEventListener(‘beforeunload’, (event) => {
// Set the returnValue property to display a confirmation dialog
event.preventDefault(); // Some browsers require this call
event.returnValue = ”; // A string value is required in some browsers
});”);

Best Regards,
Alaa
