Ajx tab extender with validations in asp.net page

Question

Hi,
   i am using ajax tab control in my asp.net page and also using validation controls for textboxes, dropdownlist, radio buttons ect under each tab. My problem is if i click on submit button i am unable to see the validations like where i missed field to enter. for example i entered all the fields in tab1 and tab3 but i missed to enter fields in tab2, and now iam in tab3 and click on submit button. here i am unable to see validations in tab2. if i go and click on tab2 it will disappear suddenly. how to go to the tab in which i missed to enter the fields after click on submit button. please can anybody help me?
