I have a directory structure type tree class written and I'm not too sure how to go about rendering it so that I can handle postbacks. I have no problem envisioning an algorithm to go through the tree, but how would I go about rendering something such as an <asp:ImageButton> for each directory on the fly as I go through the tree. I can't just slap a label on there and fill it with "<asp:ImageButton>s", right? Maybe? I'm not sure about that.<BR><BR>The only thing I can think of, short of doing it the old fashioned way of just spitting out HTML, and writing JS to handle it, is building an array as I go through the tree, and then binding that to some type of Repeater that contains an ImageButton. <BR><BR>Any thoughts suggestions? It would be greatly appreciated. Thanks.
