I am elaborating on how to set the window style to behave like the context menu or the combo-box drop down list - to be able to close when user clicks outside the window area or presses Escape but I have found no clue.
I have already used the ToolStripDropDownButton to simulate this behavior quite well but there is one big issue that the parental window loses focus and I am unable to restore it for the time the drop down window is active. Any help?
