</asp:CompareValidator>

推荐答案

尝试这个，这里我们使用Ajax calander控件来获取dd / mm / yyyy格式的输入，然后使用比较验证器

Try this, here we use the Ajax calander control to get the input in dd/mm/yyyy format and then use the compare validator

 <asp:TextBox ID="txtStart" runat="server"></asp:TextBox>
            <cc1:CalendarExtender ID="txtStart_CalendarExtender" runat="server" 
                Enabled="True" TargetControlID="txtStart">
            </cc1:CalendarExtender>
            <asp:CompareValidator ID="CompareValidator1" runat="server" 
                ControlToCompare="txtEnd" ControlToValidate="txtStart" 
                ErrorMessage="CompareValidator"></asp:CompareValidator>

        </div>
        <p>
            <asp:TextBox ID="txtEnd" runat="server"></asp:TextBox>
            <cc1:CalendarExtender ID="txtEnd_CalendarExtender" runat="server" 
                Enabled="True" TargetControlID="txtEnd">
            </cc1:CalendarExtender>
        </p>
        <asp:Button ID="Button1" runat="server" Text="Button" />
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
