Deselecting Caret for IntegerUpDown

[Kuumba123]

sorry but I couldn't figure out how to slove this issue . You know if click outside a search-bar/text-box in most website it deselects the caret so that your no longer typing into the textbox ? How do I do that for the IntegerUpDown ? I thought all you had to do was call the focus function for some other UI element but that doesnt seem to work at all.
