i have a one application which is migrated from .net 1.1 to .net 3.5 , But in .net3.5 required field validators are not working on onblur means while leaving textbox.
 
Thanks in advance.

I think the problem is with required field validator's SetFocusOnError property. Setting SetFocusOnError="false"
