title: DropDownList and RequiredFieldValidator control
body: <p>I am using dropdownlist control and a RequiredFieldValidator control for that ddl  inside the gridview. </p>
  
  <pre><code>&lt;asp:DropDownList ID="ddlInsert" runat="server" CssClass="normal" DataSourceID="sqlDataSource" DataTextField="Name"  DataValueField="ID" SelectedValue='&lt;%# Bind("ID") %&gt;'  AppendDataBoundItems="true"&gt;
                &lt;asp:ListItem  Text="--Select--" Value="-1" Selected="True" /&gt;
                &lt;/asp:DropDownList&gt;
                 &lt;asp:RequiredFieldValidator ID="requiredDDL" runat="server" ControlToValidate="ddlInsertRegion" ErrorMessage="*" InitialValue="-1" Display="Dynamic"&gt;&lt;/asp:RequiredFieldValidator&gt;
  </code></pre>
  
  <p>But this validator is not working</p>
