An InvalidOperationException is thrown from SfTextBoxExt when the TextBox has the Keyboard-Focus and the
Dispose-Method is called.
This happens with Version 15.2.0.40 and 15.2.0.43. With Version 15.1.0.41 everything works well.
The Exception-Details are:
Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.
