日期格式RangeValidator控件 [英] Date format in RangeValidator

问题描述

我使用RangeValidator控件验证日期在文本框中输入其工作罚款与缺省日期格式，但现在我想在DD / MM / YYY，但此日期格式的生成excption的日期格式。请提供给我的解决方案
我的code：

在aspx页面：

 ＆LT; ASP：文本框ID =txtrequiredby=服务器＆GT;＆LT; / ASP：文本框＆GT;
＆LT; CC1：CalendarExtender ID =txtrequiredby_CalendarExtender格式=DD / MM / YYYY
=服务器启用=真的TargetControlID =txtrequiredby＆GT;
＆LT; / CC1：CalendarExtender＆GT; ＆LT; ASP：RangeValidator控件ID =rvreqby=服务器的ErrorMessage =必选日期
大于或等于为当前日期的ControlToValidate =txtrequiredby
 显示=动态类型=日期＆GT;＆LT; / ASP：RangeValidator控件＆GT;
 

在codebehind：

  rvreqby.MinimumValue = clsGeneral.FromSqlDate（DateTime.Now）;
rvreqby.MaximumValue = clsGeneral.FromSqlDate（DateTime.Now.AddYears（200））;公共静态字符串FromSqlDate（DateTime的日期）
{
   与Date.toString返回（DD / MM / YYYY）;
}
 

解决方案

＆MinimumValue放大器; MaximumValue需要在Page_ preRender事件被设置并出现需要的日期格式为DD-MM-YY......看到的 RangeValidator控件最小值最大值错误

 保护无效Page_ preRender（对象发件人，EventArgs的发送）
{
    RangeValidator1.MinimumValue = DateTime.Now.Date.ToString（DD-MM-YY）;
    RangeValidator1.MaximumValue = DateTime.Now.Date.AddYears（90）的ToString（DD-MM-YY）;
}
 

I am using RangeValidator to validate date enter in textbox and its working fine with default date format but now i want the date format in "dd/MM/yyy" but its generating excption with this date format. please provide me solution my code:

in aspx page:

<asp:TextBox ID="txtrequiredby" runat="server" ></asp:TextBox >
<cc1:CalendarExtender ID="txtrequiredby_CalendarExtender" Format="dd/MM/yyyy"
runat="server" Enabled="True" TargetControlID="txtrequiredby" >
</cc1:CalendarExtender >

 <asp:RangeValidator ID="rvreqby" runat="server" ErrorMessage="Required By Date
Greater Than or Equal to current date" ControlToValidate="txtrequiredby" 
 Display="Dynamic" Type="Date" ></asp:RangeValidator >

in codebehind:

rvreqby.MinimumValue = clsGeneral.FromSqlDate( DateTime.Now);
rvreqby.MaximumValue = clsGeneral.FromSqlDate( DateTime.Now.AddYears(200));

public static string  FromSqlDate(DateTime  date)
{
   return date.ToString("dd/MM/yyyy");
}

解决方案

MinimumValue & MaximumValue need to be set in the Page_PreRender event and appear to require the date format as "dd-MM-yy"...see last post on Rangevalidator Min Max Value error

protected void Page_PreRender(object sender, EventArgs e)
{
    RangeValidator1.MinimumValue = DateTime.Now.Date.ToString("dd-MM-yy");
    RangeValidator1.MaximumValue = DateTime.Now.Date.AddYears(90).ToString("dd-MM-yy");
}
