推荐答案

通常，客户端验证更有效.

Normally client side validation is more effective.

function compareDate()
{

var start = document.getElementById('postedtxtboxid').value;
var end = document.getElementById('exptxtboxid').value

var stDate = new Date(start);
var enDate = new Date(end);
var compDate = enDate - stDate;

if(compDate >= 0)
return true;
else
{
alert("Please Enter the correct date");
return false;
}

您好，

希望这会对您有所帮助.

Hello,

Hope this will help you..

<asp:TextBox ID="txbPostedDate" runat="server" />
<asp:TextBox ID="txExpireDate" runat="server" />
<asp:CustomValidator OnServerValidate="ValidateDates"

    ErrorMessage="Expiry Date Should not be less than posted date" runat="server" />

在处理程序背后的代码中

In the code behind handle the handler

protected void ValidateDates(object sender, ServerValidateEventArgs e)
{
    DateTime expire= DateTime.Parse(txExpireDate.Text);
    DateTime posted= DateTime.Parse(txbPostedDate.Text);

     TimeSpan ts =posted - expire;

    e.IsValid = td.Days>0;
}

谢谢!!!!

Thanks!!!!
