'System.Reflection.TargetInvocationException' occurred in PresentationFramework.dll

Question

Okay, I have a bit of a weird bug...

This works fine:

private void radioButtonNormalPoint_Checked(object sender, RoutedEventArgs e)
{
   //comboBoxNormal         


        

Answer 1

I think you will have fewer problems if you declared a Property that implements INotifyPropertyChanged, then databind IsChecked, SelectedIndex(using IValueConverter) and Fill(using IValueConverter) to it instead of using the Checked Event to toggle SelectedIndex and Fill.
