Why doesnt this work ?
The following script is within an ItemTemplate hence the Container.FindControl..
if (sender.get_id == $find('<%# Container.FindControl("RadComboBox1").ClientID %>').get_id ) {
j = 0;
} else if (sender.get_id == $find('<%# Container.FindControl("RadComboBox2").ClientID %>').get_id) {
j = 1;
} else if (sender.get_id == $find('<%# Container.FindControl("RadComboBox3").ClientID %>').get_id) {
j = 2;
}
