DocumentContainer

[Erik Renaud]

I am trying to capture an event that would signify that a loaded document is closing.

After adding a new UserControl to the Items collection, i try registering for the DocumentClosing event but don't receive anything.

Any thoughts ?

Hi Erik,

Currently it is not possible to capture an event that would signify that a loaded document is closing. This has been considered as a defect with the Document Container. This will be fixed once DocumentContainer integration with DockingManager gets implemented.

Please let us know if you have any questions.

Thanks for your interests in Syncfusion products.

Regards,
Bala.

Has this defect been rectified yet?

Hi Paw,

Thank you for your interest in Syncfusion products.

We have implemented an event called DocumentClosing associated with the Document Container, using which you can achieve your requirements. Kindly make use of the code snippet for more idea.

In Document Container control:

[XAML]





[C# Code]

private void DocumentContainer_DocumentClosing(object sender, CancelingRoutedEventArgs e)
{
MessageBoxResult res = MessageBox.Show("Do you really want to close this window?", "Attention", MessageBoxButton.YesNo, MessageBoxImage.Asterisk);
e.Cancel = !(MessageBoxResult.Yes == res);
}


In DockingManager control:

[XAML]

ContainerMode="MDI">
syncfusion:DockingManager.Header="Docking Manager"
/>


[C# Code]

private void DockingManager_DocumentClosing(object sender, CancelingRoutedEventArgs e)
{
MessageBoxResult res = MessageBox.Show("Do you really want to close this window?", "Attention", MessageBoxButton.YesNo, MessageBoxImage.Asterisk);
e.Cancel = !(MessageBoxResult.Yes == res);
}

Please let me know if you have any question.

Regards,
SudhaC.

Thanks SudhaC,

I am using the Docking Manager.
If the user opens the tab-context menu and clicks "Close" then the DocumentClosing event does not fire, I can catch CloseButtonClick but this event does not allow me to cancel the closure of the document.
I am missing something?

FYI for now I have solved this problem by implementing my own context menu on the tab item:

XAML:



















C# Code-behind:

private void Tab_Close(object sender, RoutedEventArgs e)
{
// check if closing should be cancelled (add your own implementation)
if (!WasCanceled...)
{
// close the window
dockingManager.Children.Remove(dockingManager.ActiveWindow);
}
}
private void Tab_Float(object sender, RoutedEventArgs e)
{
dockingManager.ActiveWindow.SetValue(DockingManager.StateProperty, DockState.Float);
}

private void Tab_Dock(object sender, RoutedEventArgs e)
{ dockingManager.ActiveWindow.SetValue(DockingManager.StateProperty, DockState.Dock);
}

private void Tab_Document(object sender, RoutedEventArgs e)
{ dockingManager.ActiveWindow.SetValue(DockingManager.StateProperty, DockState.Document);
}
