Posted by Darren Clark at 1/13/2006 12:37:02 AM

Adding action buttons to my control's design-time properties page
Posted by object01 NO[at]SPAM gmail.com at 1/9/2006 6:38:42 AM
I've seen controls like the DataAdapter provide clickable hyperlinks (well, maybe not hyperlinks, but blue underlined text) in the description panel of its Properties page. I'm building a subclass of an ASP.NET Image control, and would like a button in its Properties page labeled "Fit." When c...more >>
