Forms Data Controls :: How To Put Tooltip In Dropdownlist Bind With Sqldatasource

Mar 4, 2010

I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,

item.Attributes.Add("title", someotherdatabasefield);

The end result would be something like this where the text for 'title' comes from the database

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>

Mar 24, 2010

I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?
