CompareValidator中的日期格式问题 [英] Date format problem in CompareValidator

问题描述

 <   asp:TextBox   ID    txt_dateofjoin "  runat   服务器" / <   cc1:CalendarExtender     ID   ="   runat   服务器"  TargetControlID    txt_dateofjoin" 格式   dd-MM-yyyy"  TodaysDateFormat    dd-MM-yyyy" >  <  > 

<   asp:TextBox     ID   ="   runat   服务器" / <   cc1:CalendarExtender     ID   ="   runat   服务器" 格式   dd-MM-yyyy"  TargetControlID   ="     ="   dd-MM-yyyy" > 
<  /cc1:CalendarExtender  > 

<   asp:CompareValidator     ID   ="   runat   服务器"  ControlToCompare    txt_dateofjoin"  ControlToValidate    txt_confirmationdate" 操作员  ="    类型  ="     SetFocusOnError   ="  显示  ="    文本  =" 确认日期必须大于加入日期" / >  

当我将CalendarExtender的格式更改为MM-dd-yyyy时，它可以正常工作，但在dd-MM-yyyy中，比较验证器将日期考虑为月份.现在，我如何才能以dd-MM-yyyy格式验证这两个日期.

解决方案

尝试在CompareValidator 中设置属性CultureInvariantValues="true".

通过以下方式重写日历扩展器的标签，即可解决您的问题...

 <   cc1:CalendarExtender     ID   ="     runat   =" 服务器"  TargetControlID    txt_dateofjoin" 
 格式  ="   TodaysDateFormat    dd/MM/yyyy" "><  /cc1:CalendarExtender  >  

<asp:TextBox ID="txt_dateofjoin" runat="server" />
<cc1:CalendarExtender ID="cal2" runat="server" TargetControlID="txt_dateofjoin" Format="dd-MM-yyyy" TodaysDateFormat="dd-MM-yyyy"></cc1:CalendarExtender>

<asp:TextBox ID="txt_confirmationdate" runat="server" />
<cc1:CalendarExtender ID="cal" runat="server" Format="dd-MM-yyyy" TargetControlID="txt_confirmationdate" TodaysDateFormat="dd-MM-yyyy">
</cc1:CalendarExtender>

<asp:CompareValidator ID="cmpDates" runat="server" ControlToCompare="txt_dateofjoin" ControlToValidate="txt_confirmationdate" Operator="GreaterThan" Type="Date" SetFocusOnError="true" Display="Dynamic" Text="Confirm Date must be greater than Joining Date" />

when I change the Format of CalendarExtender to MM-dd-yyyy then it works fine but in dd-MM-yyyy compare validator consider date to month. Now how I can validate this two date in dd-MM-yyyy format.

解决方案

Hi,
Try setting the property CultureInvariantValues="true" in your CompareValidator .

Rewrite your tag for calender extender in following way its solved your problem...

<cc1:CalendarExtender ID="cal2" runat="server" TargetControlID="txt_dateofjoin"

Format="dd/MM/yyyy" TodaysDateFormat="dd/MM/yyyy"></cc1:CalendarExtender>
