ASP.NET DropDownList and RequiredFieldValidator

Adding a RequiredFieldValidator to a DropDownList can be done fairly easily like this:

Add the following code into your aspx page,

<asp:DropDownList ID="ddlExample" runat="server">
</asp:DropDownList>

<asp:RequiredFieldValidator ID="rfvExample" runat="server"
ControlToValidate="ddlExample" ErrorMessage="*" InitialValue="0"></asp:RequiredFieldValidator>

In your codebehind,

 ddlExample.Items.Insert(0, New ListItem("Make a selection", "0"))
 ddlExample.Items.Insert(0, New ListItem("retardedbloger.com", "1"))
 ddlExample.Items.Insert(0, New ListItem("retardedweblogger.com", "2"))
