Hi ,
I have a Problem in raddatePicker.
I have a form. In this, I have   RadDatePicker, RadCombobox and radbutton Controls and trhese are mandatory fields. on Button click it will call the Callout Extenders for mandatory Fields. In my Form First is RadDatePicker And next is RadCombobox.On buttonClick it showing first calloutoutextender for Radcombox instead of RadDatePicker. I want RaddatePicker's CalloutExtender will be called First and then rest of controls.

Thanks in Advance.
