推荐答案

为此使用比较验证器
例如:-

< itemtemplate>

use compare validator for this
example:-

<itemtemplate>

<ItemTemplate>

<asp:TextBox

                id="txtDateOfPayment"

                Text='<%# Bind("DateOfPayment") %>'

                Runat="server" />
            <asp:CompareValidator

        id="cmpDate"

        Text="(Invalid Date)"

        ControlToValidate="txtDateOfPayment"

        Type="Date"

        Operator="DataTypeCheck"

        Runat="server" />
</ItemTemplate>
