推荐答案

您可以使用 CompareValidator [ ^ ] you can use CompareValidator[^] <asp:CompareValidator ID="CompareValidator1" runat="server" ControlToCompare="txtStartDate" ControlToValidate="txtEndDate" Display="Static" ErrorMessage="'End Date' must not be earlier than 'From Date'" Text="*" Operator="GreaterThanEqual" SetFocusOnError="True" Type="Date">

ref： http：/ /stackoverflow/questions/12247314/using-javascript-custom-validator-to-check-start-date-and-finish-date [ ^ ] 如果您有自定义规则来验证使用，请使用 CustomValidator [ ^ ] stackoverflow/questions/2309912/asp-net-validator-to-compare-two-date-difference-is-not-more-than-12-months [ ^ ]

ref: stackoverflow/questions/12247314/using-javascript-custom-validator-to-check-start-date-and-finish-date[^] if you have custom rules to validate use then use CustomValidator[^] stackoverflow/questions/2309912/asp-net-validator-to-compare-two-date-difference-is-not-more-than-12-months[^]

最好使用比较验证器就像Damith说的那样你还有两个选择 请参考： forums.asp/t/1480183.aspx?Using+CustomValidator+to+validate+Date+Format+in + dd + MM + yyyy [ ^ ] Better you use Compare Validator like Damith says and you have two more choices please refer this: forums.asp/t/1480183.aspx?Using+CustomValidator+to+validate+Date+Format+in+dd+MM+yyyy[^]
