根据当前系统日期时间值检查RadDateTimePicker值 [英] check RadDateTimePicker value against current system date time value

问题描述

如何使用服务器端验证从 RadDateTimePicker 中选择的日期时间值是否大于 asp.net中的当前系统日期时间值。

How can I verify if the selected datetime value from the RadDateTimePicker is greater then the current system datetime value in asp.net using server side validaton.

<telerik:RadDateTimePicker runat="server" ID="orderDate" >
      <Calendar ID="Calendar1" runat="server" EnableKeyboardNavigation="true">
        </Calendar>
</telerik:RadDateTimePicker>

推荐答案

要进行验证，您需要使用CompareValidator或CustomValidator

To validate it, you need to use CompareValidator or CustomValidator.

请为日期时间选择器使用以下标记：

Please use following markup for datetime picker:

<telerik:RadDateTimePicker runat="server" ID="orderDate">
   <Calendar ID="Calendar1" runat="server" EnableKeyboardNavigation="true">
   </Calendar>
</telerik:RadDateTimePicker>
<asp:CustomValidator ID="cvOrderDate" runat="server" ControlToValidate="orderDate" ValidationGroup="vgSubmit" ErrorMessage="Please use correct date" OnServerValidate="cvOrderDate_ServerValidate"></asp:CustomValidator>

后面的代码：

protected void cvOrderDate_ServerValidate(object source, ServerValidateEventArgs args)
{
  args.IsValid = orderDate.SelectedDate.Value > DateTime.Now;
}
