Not able to add attribute on page OnInit

[Joby]

Hi,
  I have a radbutton with the name "rbtnDelete".Here i am trying to register below code on page OnInit method 

ClientScript.RegisterClientScriptBlock(this.GetType(),
"ConfirmDelete", objUtl.RadConfirmDelete(),true);
this.rbtnDelete.Attributes.Add("OnClientClicking",
"function(sender,args){ConfirmDelete(sender, args, 'dgvContactList',
'hidContactRowCount');}");

.But it is not working. But if i try to use in aspx with this code it is working fine 

 OnClientClicking="function(sender,args){ConfirmDelete(sender,args,'dgvContactList','hidContactRowCount');}"

Please help me

Hey Joby,

In your first example, why are you setting the OnClientClicking event using the Attributes collection, instead of setting the property directly on the control. This is how I would do it.

this.rbtnDelete.OnClientClicking = ".....";

I hope that helps.
