In my page,there are 2 web user controls,and I used the RadAjaxManager as well.
Every controls had been bind with RequiredFieldValidator.
The validation works when I clicke the submit button for the first time.
I mean,after I chosen a item from a combobox ,autopostback enabled,the validation would not work any more.
I think ,there must be something wrong with RadAjaxManager.
coz it works fine without RadAjaxManager.but I must use it in the page.
Thanks in advance.
