prevent tab switching

[Adam]

How would I go about preventing the tab control from switching. Say I need to validate something inside some control inside the tab and if the validation fails the tab should not be allowed to switch?

Try this:
private void tab_SelectionChanged(object sender,RoutedEventArgs e)
{
       if (bisRefreshing)
          ((Telerik.Windows.Controls.RadSelectionChangedEventArgs)(e)).Handled = true;
}

Hi Adam,

With Q3.09 we are adding the PreviewSelectionChanged event for the RadTabControl. By using this event you will be able to prevent the user from selecting a particular node. The release will be live this week.

Kind regards,

I am having to use the code below - which I don't think I should need:

        private void TabControl_PreviewSelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangedEventArgs e)
        {
            RadTabItem navTo = e.AddedItems[0] as RadTabItem;
            if (navTo.Visibility == Visibility.Collapsed)
            {
                e.Handled = true;
            }
        }

When my app starts only one tab is visible.  Making choices on the main tab makes other tabs visible.  However, if the user clicks in a textbox and hits the right arrow twice they are taken to the second tab, even though it is supposed to be 'invisible'.

Thanks,

Hi Larry,

Unfortunately I was not able to reproduce the issue. I have attached my sample project. Could you please take a look at it let me know the steps to reproduce the problem.
