I've noticed there is no OnClientClick() property for the radiobuttonlist in the ASP.NET control set. Is this a purposeful omissiong on Microsoft's part? Anyway, I've tried to add OnClick to the radio button list like so:

For Each li As ListItem In rblSearch.Items
          li.Attributes.Add("OnClick", "javascript:alert('jon');")
Next

But alas, it doesn't work. I've even checked the source in firebug, and there is no javascript shown in the radiobuttonlist. Does anyone know how to get this very simple thing working? I'm using ASP.NET control adpaters so don't know if that has anything to do with it.

(I wish asp.net/javascript would just work out the box!!!)
