Restricting the Usage of Specific Tabs
You can add a handler to the SelectedIndexChanging event to test whether the index of the page is the page that you don't want the user to switch to. If so, e.Cancel would be set to True. For example, the following code shows how to add a handler to the SelectedIndexChanging event:
To write code in Visual Basic
Private Sub c1DockingTab1_SelectedIndexChanging(sender As Object, e As C1.Win.C1Command.SelectedIndexChangingEventArgs)
If e.NewIndex = 1 And e.CanCancel Then
e.Cancel = True
End If
End Sub
To write code in C#
private void c1DockingTab1_SelectedIndexChanging(object sender, C1.Win.C1Command.SelectedIndexChangingEventArgs e)
{
if(e.NewIndex == 1 && e.CanCancel)
e.Cancel = true;
}
