Are there compatibility issues with DataList that prevent it from being ajaxical? I have an asp:LinkButton inside a DataList and I would like for this linkbutton to set a Panel's visibility to true and then update the text of a label within that panel. Doesn't seem to work. I have a similar question posted in the .net forum (here) but I think it might be more appropriate to ask it in this forum.

Kind of narrowing down what exactly is causing the problem. When I call WebClient.DownloadFileAsync it seems to prevent updates to the page until the download is complete. So.. if I have a function that sets the Text of a label to the current time, then makes the call to DownloadFileAsync, the text for the label isn't changed until after the download finishes.
