Use compare validator, and put those validation next to your text boxes.
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> <asp:CompareValidator ID="CompareValidator1" runat="server" ErrorMessage="CompareValidator" ControlToValidate="TextBox2"></asp:CompareValidator>
</EditItemTemplate>
