Hi

Is this programmatically feasible:

1) Here is the control

        <Columns>
          <asp:TemplateColumn HeaderText="Open Date">
            <ItemTemplate>
              <%# DataBinder.Eval(Container.DataItem, "OpenDate") %>
            </ItemTemplate>
            <EditItemTemplate>
              <asp:TextBox id="txtOpenDate" Size="25"
                   Text='<%# DataBinder.Eval(Container.DataItem,"OpenDate") %>'
                   runat="server"/>
            </EditItemTemplate>
          </asp:TemplateColumn>

2) And here is the validation element.
  Protected Sub ValidateData(Source As Object, args As System.Web.UI.WebControls.ServerValidateEventArgs)
     args.IsValid = False
         Dim date_open As Date

        Try
            date_open = Date.Parse(txtOpenDate.Text)
      Catch ex As Exception
            feedbackLabel.Text = "Invalid data entry: Depature date is Invalid. " _
                   + "Enter a valid date, for example: 2003/01/02"
         Return
    End Try
     args.IsValid = True
  End Sub

When I try it I get an error saying txtOpenDate.Text is undeclared even though txtOpenDate is a textbox ID.

Am I missing the point?

Thanks
