Few days back I was creating a user control like ComboBox. In ComboBox we have a Drop Down button at the right side, which cannot have focus. This button can only be clicked by mouse to open the Drop Down portion (Alt+Down is the shortcut).
Similarly my control also have a button on right. I decided to make that button just like the Drop Down button of ComboBox. For this purpose I added a plain Class in my project and then put the following Code,
Public Class NotSelectableButton
Public Sub New()
' following line will make this button Not Focusable
