我需要结束时间必须大于开始时间

问题描述

我有一个开始时间，结束时间在我的网页上。

我需要结束时间必须大于开始时间，开始时间是当前时间和结束时间是用户输入使用Masked Extender

。如何实现此验证？

I am having a start time,end time on my web page.
I need to end time must be greater than start time and start time is current time& end time is user entry using Masked Extender
.How can I achieve this validation?

推荐答案

<asp:Textbox runat="server" ID="TextBox1" />
<asp:CustomValidator runat="server" ControlToValidate="TextBox1" ErrorMessage="Date was in incorrect format" OnServerValidate="CustomValidator1_ServerValidate" />

代码落后：

Code behind:

protected void CustomValidator1_ServerValidate(object sender, ServerValidateEventArgs e)
{
    DateTime d;
    e.IsValid = DateTime.TryParseExact(e.Value, new[] { "dd/MM/yyyy", "yyyy-MM-dd" }, CultureInfo.InvariantCulture, DateTimeStyles.None, out d);
}

== OR ==

==OR==

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:CompareValidator ID="DateValidator" runat="server" Operator="DataTypeCheck"
        Type="Date" ControlToValidate="TextBox1" ErrorMessage="Bad format" />

祝你好运，

<asp:CustomValidator ID="cstmvEndDate" ControlToValidate="txtEndTime" ClientValidationFunction="compareTime" Display="Dynamic" ErrorMessage="End time should be greater than Start time!" ValidationGroup="Validation"runat="server" />
