The code is correct. Maybe when the for loop is executed, there are no items in checkboxlist.

OK - weird - I am databinding my cbl in the page load and then setting the OnDataBound to the below - but when I view the rendered source - nothing is there?
        foreach (ListItem li in ULCheckBoxList1.Items)

        {

            li.Attributes.Add("onclick", "javascript:alert('test');");

        }

Why in OnDataBound. You should do it in Page load itself.... after calling DataBind()

even when I put it in the page load - I do not see it in the rendered html

            ULCheckBoxList2.DataBind();
            foreach (ListItem li in ULCheckBoxList1.Items)
            {
                li.Attributes.Add("onclick", "javascript:alert('test');");
            }

besides the above - this is it
                                    <asp:CheckBoxList  ID="ULCheckBoxList1" runat="server" CellPadding="0" CellSpacing="0"

                                        CssClass="colorCheck">

                                        <asp:ListItem id="aa"  >ICD9 Codes (2007 updates included): </asp:ListItem>

                                    </asp:CheckBoxList  >

You are not setting datasource.. then why do databind?
also if it is a static list, then you can add the onclick directly in the html code. why loop thru in the code behind?
