Hope this[^] might help you.

You can use given sample code to adding tooltip to DropDownList. you need to just adding Title attribute to the list item in DataBound event.

<asp:dropdownlist id="DropDownList1" runat="server" ondatabound="DropDownList1_DataBound" xmlns:asp="#unknown">
</asp:dropdownlist>

and Now below code in Code behind file

protected void DropDownList1_DataBound(object sender, EventArgs e)
{
    DropDownList ddl = sender as DropDownList;
    if (ddl != null)
    {
        foreach (ListItem li in ddl.Items)
        {
           li.Attributes["title"] = li.Text; // setting text value of item as tooltip
        }
    }
}
