I created a user control called ucDateTime that consists of a DTPicker and 3 command buttons; Clear, Quit and Set. I have a textbox on a form called txtDate that is populated with a date and time. When the user clicks on the textbox, it becomes invisible and the ucDateTime control becomes visible in its place and populated by its value(Now if it is blank). The user can click Clear to remove the date and leave txtDate blank, Quit to leave txtDate as it was or they can select a date/time and click Set to move the value to txtDate. I haven't worked out all the bugs yet but I'm close. When I stop the app and return to the form design, the user control has diagonal lines thru it. Can someone tell me what that is and how I might correct it?

Thanks,

Greg
