Responding to close event on XamTabControl

Simon posted over 16 years ago

How do i wire up an event to the TabHeaderClose button on a XamTabControl, so that I can do a "Do you want to save" before the tab is closed.

thanks, that works, but ... if I want to prompt the user.....

MessageBoxResult res = MessageBox.Show("Do you want to save changes to '" + tabItem.ItemName + "'",tabItem.ItemName,MessageBoxButton.YesNoCancel,MessageBoxImage.Question, MessageBoxResult.Cancel);

how to I cancel the tab closure ? setting Handled = true; doesnt appear to work ,

if (res == MessageBoxResult.Cancel)
{
args.Handled = true;
}

The TabItemEx.Closing event is a bubble routed event so you can handle it on the TabItemEx or the xamTabControl by either adding a handler for this event in code or in xaml.

e.g. to handle this on the tabcontrol:

    <igWindows:XamTabControl

        igWindows:TabItemEx.Closing="XamTabControl_Closing"

        ShowTabHeaderCloseButton="True">

private void XamTabControl_Closing(object sender, Infragistics.Windows.Controls.Events.TabClosingEventArgs e)

{

    TabItemEx tab = e.OriginalSource as TabItemEx;

    // TODO

}
