I have a Control that inherits from WebControl.Image<BR>Annother control that is funky at design-time, but function exactly as expected at run-time.<BR><BR>When the ImageUrl property is set, I want to put parts of the Url in one property and the rest in annother.<BR><BR>This goes ok, I give a value for ImageUrl in the Properties window, the Property Set splits up the value and sets the 2 other properties. <BR>The problem is that these new values, while visible in the properties window are not saved as html properties. Changing the value by typing in the properties will cause the props to be peristed to the html.<BR><BR>Understand the problem?<BR>Got an Idea?<BR><BR><BR><BR><BR>
