Hello,
i use a radwindow, and when i cancel the PreviewClosed Event, it loop two times in my event,
Any idea ?
My Code :
this.PreviewClosed += new EventHandler<WindowPreviewClosedEventArgs>(RadWindow_PreviewClosed);
private void RadWindow_PreviewClosed(object sender, WindowPreviewClosedEventArgs e)
{
if (validatorManager.globalFormChange)
{
e.Cancel = true;
RadWindow.Confirm(new DialogParameters
{
Header = "Enregistrement",
Content = "Souhaitez vous enregistrer avant de quitter?",
IconContent = "",
OkButtonContent = "Oui",
CancelButtonContent = "Non",
Closed = new EventHandler<WindowClosedEventArgs>(OnPreviewClosePopup)
});
return;
}
}
}
I use Q1 2010 309.
Thank you.

I were able to reproduce this problem. I logged it in PITS and we will fix for one of the upcoming releases. The title of the issue is "PreviewCloseEvent of the Window is thrown twice of the preview is canceled.".

Hi,
We're having this issue too.
I cancel on the PreviewClosedEvent, tell my UIManager component that the view thats hosted inside this window wants to close and pass a callback that the view's viewmodel will call which confirms if the window can close or not.
As a work around I'm applying states to the window to know exactly when it can close.
It's not elegant but it works..

void window_PreviewClosed(object sender, WindowPreviewClosedEventArgs e) |
{ |
var window = sender as RadWindow; |
var view = GetView(window); |
if (window.Tag == "CAN_CLOSE") |
return; |
if (window.Tag == "CLOSING") |
{ |
e.Cancel = true; |
return; |
} |
//window.Tag is null here |
e.Cancel = true; |
window.Tag = "CLOSING"; |
manager.TryClose(view, res => |
{ |
if (res) |
{ |
window.Tag = "CAN_CLOSE"; |
window.Close(); //forces PreviewClosed, hence CAN_CLOSE |
} |
window.Tag = null; |
}); |
} |
It's not elegant but it works..

This issue will be fixed in one of the upcoming releases. Unfortunately I cannot tell exactly when it is going to be fixed, because it is not scheduled yet.
