Hi,$0 My problem is that i can't call any functions from clientside events like OnRowSelected,OnColumnMouseOver etc in fireFox ..But if i put alert directly on this events it will activate...If i write functions like OnColumnMouseOver(); it will call in FireFox.I want the solution for OnRowSelected(passingParameter1,para2). What are the parameters we want to pass for calling this function.Thanks$0$0eg:- <ClientEvents OnRowSelected="RowSelected(?,?);"/>$0$0 </ClientSettings>$0$0$0$0$0$0<script language="javascript" type="text/javascript">$0$0$0$0$0function RowSelected(rowObject,eventObject)$0$0{$0$0 alert('selected '+ rowObject.Index +' Row');$0$0}$0$0</script>$0$0
