After selecting combo item programmatically via SelectedIndex property the combo does not refresh until mouse is moved over it.
This can be solved by calling Refresh() but I suppose there is more appropriate way to solve it in the control design (but I don't know how) so I'm posting it as an issue rather than pull request.
Fixed in PR #342
Added an improvement to ComboBox, which I personally used in my applications. When hit Del key or Backspace, the index of ComboBox will become -1.
