       here is the another way to show confirm box extender +modelpopup extender. to show attractive confirmbox extender.

Try this

try this code
onclientclick="return confirm('Are you sure want to delete current record')"
tell me this code is working or not

Instead of writing Confirmation message on code-behind, create a javascript function and bound it to Button's event.

 Because in future if you want to change the Confirmation message, you need to change in code-behind resulting in
 
 uploading of dlls again.

 

 On Page Load

 btn1.Attributes.Add("onclick", "javascript:if(DeleteMe()==false) {return false;};");
