Exception on casting to HandledMouseEventArgs
Posted on 2012-12-21
This should be simple but ... I have this event handler on a textbox to ignore right mouse clicks. When it executes I get InvalidCastException on the 3rd line.
private void txtUserName_MouseDown(object sender, MouseEventArgs e) {

}
