Tooltip on asp:dropdown

Question

I have a user control that loads a asp:dropdownlist via an asp:datasource: What i need to do is show a tooltip on each dropdown value.

Here is my code:

<asp:dropdownlist id="lstBusinessUnit" runat="server" 
                            appenddatabounditems="True"
                            width="200px" 
                            datasourceid="sqlBusinessUnit" 
                            datatextfield="sBusUnitDisplay" 
                            datavaluefield="sBusUnitCode"
                            >


 <asp:sqldatasource id="sqlBusinessUnit" runat="server" 
    connectionstring="<%$ ConnectionStrings:Database %>" 
    selectcommand="SELECT [sBusUnitCode],[sBusUnit], [sBusUnitDisplay] FROM [tBusinessUnits] ORDER BY [sBusUnitDisplay]" />

What i need is for sBunit to be the tooltip for each value. Please help. Thanks.

You should add an attribute title to each of your listitem in code behind

 foreach (ListItem item in lstBusinessUnit.Items)
 {
     item.Attributes.Add("Title", "your tooltip");
 }
