有关比较验证器的问题 [英] Problem about compare validator

问题描述

我使用比较验证器的日期应该小于当前日期。但它出现以下错误

i am using compare validator for date should be less then current date. but it gives following error "

The value '29/Nov/2016' of the ValueToCompare property of 'CompareValidator8' cannot be converted to type 'Date'.

< asp：TextBox ID =TxtCreatedOnrunat =serverCssClass =fortxtboxonkeypress =return isDATENumberKey（event）

TabIndex =2>

< ajax：calendarextender id =CalendarExtender1runat =servertargetcontrolid =TxtCreatedOnformat =dd / MMM / yyyy>

What I have tried:

<asp:TextBox ID="TxtCreatedOn" runat="server" CssClass="fortxtbox" onkeypress="return isDATENumberKey(event)"
TabIndex="2">
<ajax:calendarextender id="CalendarExtender1" runat="server" targetcontrolid="TxtCreatedOn" format="dd/MMM/yyyy">

<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="TxtCreatedOn"

SetFocusOnError="true" ToolTip="Please Enter Date for CreatedOn." ValidationGroup="CommonForSave">*
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="Please Enter Correct Date for CreatedOn."
ControlToValidate="TxtCreatedOn" SetFocusOnError="true" ValidationExpression="^(([0-9])|([0-2][0-9])|([3][0-1]))\/(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)\/\d{4}$"
Font-Size="Small" ForeColor="#CC3300" ToolTip="Please Enter Correct Date for CreatedOn."
