'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

To diagnose this issue, place the line of code causing the TargetInvocationException inside the try block.

To troubleshoot this type of error, get the inner exception. It could be due to a number of different issues.

try
{
    // code causing TargetInvocationException
}
catch (Exception e)
{
    if (e.InnerException != null)
    {
    string err = e.InnerException.Message;
    }
}
