Thanks Katy,
I looked at your example Configurable Description and can see how that might work. But I think your first approach might be the better way to go--having a tool that opens up a search dialog box. I had a couple of follow up questions on that approach.
So there is already a Search tool available for the Viewer. Is it possible to intercept the text from that search tool to do my own search, and bypass the default searches that come with that tool (so in other words, customize that existing search tool)? If that is not possible, it would be good to be able to create something as similar to that as possible. Is there any code available for a similar window? Also, I noticed the Search panel shares the same space as the Map Contents list (resizing the width of one, resizes the other). Is it possible to create a custom dialog for a tool that also shares this same space? I�??m just not clear how you reference that space that is shared by the Search and the Map Contents dialog boxes.
Thanks.
Tom
