Before the Silverlight application exit, you can confirm whether the user really wants to exit or not.
Follow this Steps:
1.) Register ScriptableObject in the App.xaml.cs file
Follow this Steps:
1.) Register ScriptableObject in the App.xaml.cs file
private void Application_Startup(object sender, StartupEventArgs e)
{
MainPage mainPage = new MainPage();
HtmlPage.RegisterScriptableObject("myApp", mainPage);
this.RootVisual = mainPage;
}
2.) Create ScriptableMember (method) in your Silvelright application (MainPage.xaml)
[ScriptableMember]
public void AskToSaveChanges()
{
if (MessageBox.Show("Save changes?", "", MessageBoxButton.OKCancel) == MessageBoxResult.OK)
{
// Save Changess
}
}
3.) Now, in the aspx page that is hosting the Silverlight application
<script type="text/javascript">
window.onbeforeunload = saveBeforeExit;
function saveBeforeExit() {
var slApp = document.getElementById("slApp")
slApp.Content.myApp.AskToSaveChanges();
}
</script>
Note: "slApp" is the ID of the object tag which is hosting the Silvelright application.
Hope this helps.
