Hello Chetan, Yes I re-installed the TTS a few times and I still have the same error during Edit or Deleting a Category. Adding is no problem. When I check/configure the DataSource then the dropdownlist shows many methods. The Add Method is connected to his method, but the Delete and Edit are not. When I choose the Update and Delete method from the DDlist then it resets my datagrid. I can manual add the linkbuttons again. But I still have the same problem after re-building the website.
When I start in debug mode, then I see really no mistakes. 'Build succeeded and 0 errors'.
Maybe you all guys run the C# version, I have the VB version. The only thing what I cannot understand is that, when 1300 people saw this thread already and nobody, exept you Chetan, tries to help me, that everybody has a perfect application without mistakes!? When it's already not good 'out of box', then I think that the problem doesn't occur only on my pc!
But can you please describe what you see when you start this app for the first time? And what you did, or it worked ok for you after hitting only the CTRL+F5?
Thanks again for your patient.
Ps. are you the programmer behind this code? Or the developer doesn't answer in this forum... ;-)
Grtz.
