Which Validator control to check that an item is selected in a DropDownList?

I have a DropDownList with say the following 5 items:

  1. -- Department --
  2. Operation
  3. Engineering
  4. Sales

Which validator control can help to check that an item other than the 1st one is selected?

 Just add a normal RequiredFieldValidator but set the InitialValue attribute to the text of the ListItem that you want prevent from being selected.

 Here is an example:


                    <asp:DropDownList AppendDataBoundItems="True" ID="JobTypeDropDownList" runat="server"
                        SelectedValue='<%# Bind("Type") %>' DataSourceID="srcJobTypes" ValidationGroup="JobVacancyGroup">
                        <asp:ListItem>Please select a job type</asp:ListItem>
                        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="JobTypeDropDownList"
                            Display="Dynamic" ErrorMessage="Please select a job type" ValidationGroup="JobVacancyGroup"
                            InitialValue="Please select a job type"></asp:RequiredFieldValidator></div>

validate Textbox in Web User Control from web form?
ASP.NET 2.0 I have a web user control that contains a textbox.  I need to add some validation (like requiredfieldvalidator, comparevalidator, etc).

So how would I associate a validation control on my web form with the text box inside my web user control?  Can this be done; any alternatives out there? Thanks!   The error message should occur wherever you place the vali...
