ajax tab panel validation

[billcodes]

hi, I am trying to use ajax tab panels to gather information from a user. I have controls in the first tab which I would like to vaildate before moving to the second tab. Is there a way I can force the user to stay in the 1st tab if they havent satisied the validation? how to stop the user from moving to the next tab? regards, Bill

Hi, I think you must set the properties of your tab panel to autopostback=true and then in your tabpanel If tabs.ActiveTabIndex = 1 Then textbox1.Text = "sayre" End If Hope this one can help. Thanks
