c＃.net使用asp：CompareValidator和日期 [英] c#.net using asp:CompareValidator with dates

问题描述

我有一个Javascript增强文本框生成的日期格式为dd / mm / yyyy，当使用asp：comparevalidator验证时无法正确验证。

以下是相关代码：

 < asp：CompareValidator ID =CompareValidator4runat =server
 ControlToValidate =txtEndDateValueToCompare =txtStartDate
显示=无
 ErrorMessage =结束日期应大于或等于开始日期。 
 Type =DateOperator =GreaterThanEqualSetFocusOnError =True> 
< / asp：CompareValidator> 
 
< strong>开始日期< / strong>< asp：TextBox ID =txtStartDaterunat =serverWidth =215pxCssClass =textfieldStyle =width：176px; margin-left：5px;>< / asp：TextBox>& nbsp;& nbsp; 
 
< strong>结束日期< / strong>< asp：TextBox ID =txtEndDaterunat =serverWidth =215pxCssClass =textfieldStyle =width：176px; margin-left：5px;>< / asp：TextBox>& nbsp;& nbsp; 
  

如果不清楚，我希望txtStartDate中的日期早于 txtEndDate 。

当验证失败时，我会获得乱码的结果，没有明显的模式。谁能看到有什么问题？

btw我知道html有多差 - 我正在编辑别人的代码。

解决方案

您可以将页面的文化更改为 en-GB 吗？

 <％@页面语言=C＃AutoEventWireup =trueCodeFile =Default.aspx.cs
 Inherits =_ DefaultCulture =en-GB％> 
  

找到 here 。

更新您的验证器标记中有错误。如果要比较两个文本框日期，您必须提供 ControlToValidate 和 ControlToCompare （而不是 ValueToCompare ）

 < asp：CompareValidator ID =CompareValidator4 =server
 ControlToValidate =txtEndDate
 ControlToCompare =txtStartDate
 Type =DateOperator =GreaterThanEqual
显示=无ErrorMessage =结束日期应大于等于开始日期。 SetFocusOnError =True> 
< / asp：CompareValidator> 
  

I have dates generated by a Javascript enhanced textbox in the format dd/mm/yyyy, which when validated with a asp:comparevalidator fails to to validate correctly.

Here is the relevant code:

<asp:CompareValidator ID="CompareValidator4" runat="server" 
                      ControlToValidate="txtEndDate" ValueToCompare="txtStartDate" 
                      Display="None" 
                      ErrorMessage="End Date should be greater than or equal to Start Date." 
                      Type="Date" Operator="GreaterThanEqual" SetFocusOnError="True">    
</asp:CompareValidator>

<strong>Start Date</strong><asp:TextBox ID="txtStartDate" runat="server" Width="215px" CssClass="textfield" Style="width: 176px; margin-left:5px;"></asp:TextBox>&nbsp;&nbsp;

<strong>End Date</strong><asp:TextBox ID="txtEndDate" runat="server" Width="215px" CssClass="textfield" Style="width: 176px;  margin-left:5px;"></asp:TextBox>&nbsp;&nbsp;

In case it isn't clear I want the date in txtStartDate to be earlier than the one in txtEndDate.

When validated, I get gibberish results with no obvious pattern to when the validation fails. Can anyone see what is wrong?

btw I am aware of how poor the html is - I am editing someone else's code.

解决方案

Can you change the page's culture to en-GB?

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" 
Inherits="_Default" Culture = "en-GB" %>

Found here.

Update You have a bug in your validator markup. If you want to compare both textbox-dates with each other you have to provide the ControlToValidate and the ControlToCompare (not the ValueToCompare)

 <asp:CompareValidator ID="CompareValidator4" runat="server" 
    ControlToValidate="txtEndDate" 
    ControlToCompare="txtStartDate" 
    Type="Date" Operator="GreaterThanEqual"
    Display="None" ErrorMessage="End Date should be greater than or equal to Start Date." SetFocusOnError="True">
</asp:CompareValidator>
