Are you able to send me a small self-contained sample application so that I can investigate this matter further? With this information, I will be able to provide you with a possible answer to your concern. I do have 1 question for you. What type of panel are you placing in your ItemTemplate? As for the sample application, you can either send it to firstname.lastname@example.org with a reference to this forum post, or you can attach it to this forum thread. In order to attach a file, you can click on reply, then choose the 'Options' tab. From there, you can attach files to a forum post.
