在ASP.Net中的AJAX日期驗證器

我在驗證結束日期>開始日期上的問題，實際上是AJAX啓用日期遊俠的日期比較！我想知道任何內置的日期範圍驗證可用於AJAX ASP.net在ASP.Net中的AJAX日期驗證器

 <td align="left"> 
     <asp:TextBox ID="txtFromDate" runat="server" Width="100px" style="text-align:justify" ValidationGroup="MKE" /> 
     <asp:ImageButton ID="ImgBntCalc" runat="server" 
          ImageUrl="~/AJAXImages/Calendar_scheduleHS.png" CausesValidation="False" /> 

    <cc1:MaskedEditExtender ID="MaskedEditExtender5" runat="server" 
          TargetControlID="txtFromDate" 
           Mask="99/99/9999" 
           MessageValidatorTip="true" 
           OnFocusCssClass="MaskedEditFocus" 
           OnInvalidCssClass="MaskedEditError" 
           MaskType="Date" 
           DisplayMoney="Left" 
           AcceptNegative="Left" 
           ErrorTooltipEnabled="True" /> 

     <cc1:MaskedEditValidator

            InvalidValueBlurredMessage="*"

    <td align="left">

    <td align="left">

我用下面的線...... !!! if（Convert.ToDateTime（txtToDate.Text）> Convert.ToDateTime（txtFromDate.Text））{} ISSUE IS FIXED !! – goofyui 2011-06-15 21:28:53

我建議像下面使用compareTo方法

DateTime dtFrom = DateTime.Parse(txt1.Text); 
DateTime dtTo = DateTime.Parse(txt2.Text); 
if(dtFrom == null){//respond from date was invalid 
} 
if(dtTo = null){//respond to date was in valid 
} 
if(dtFrom.CompareTo(dtTo) >= 0){//You hit Jackpot 
}

一個更強大的工作代碼

CompareTo返回整數值，

when < 1, dtFrom occurs earlier than dtTo 

When = 0, dtFrom is equal to dtTo 

When > 0, dtFrom occurs after the dtTo
