Append the Items on a Dropdown Menu

This tip provides a way to append the items on a dropdown menu—even when the control is binded with the datasource.

Assume that the dropdown menu will be showing a list of employees. Binding with the datasource will fetch the employees names, but what if you want to set the first item as "All"? There is no direct provision for such a thing in ASP.NET 1.1.

However, in ASP.NET 2.0, the AppendDataBoundItems=true property will do the trick. Here's an example:

<asp:DropDownList   AppendDataBoundItems=true ID="lstTest"  Runat="server"
AutoPostBack="True" DataSourceID="sdsTest"> 
<asp:ListItem Value="All">All</asp:ListItem>
