You should change 

validate(this) return

with 

return validate(this)

in the onclientclick attribute

OnClientClick="if (!validate(this)) return;" i did this way..but not working
@Gani, what you have typed above is actually the correct answer. The actual rendered script will be something like this onclick="if(!validate(this)) return;__doPostBack(&#39;ctl00$MainContent$btn1&#39;,&#39;&#39;)" which is what you want.
@MARC with useSubmitBehavior="false" when any validation is false then a alert popup's and when i click OK on popup the page is automatically refreshing ,i dont want this to happen .How can i do this ??
