日期验证一个TextBox [英] Date validation for a textbox

问题描述

我一直在使用该功能拍摄日期毫米/ dd / yyyy格式...

I have been using this to take date as mm/dd/yyyy format...

<asp:CompareValidator ErrorMessage="(mm/dd/yyyy)" Display="Dynamic" ID="valcDate"
    ControlToValidate="txtDob" Operator="DataTypeCheck" Type="Date"     
    runat="server"></asp:CompareValidator>
<asp:RangeValidator ID="valrDate" runat="server" ControlToValidate="txtDob"  
    MinimumValue="12/31/1950"
    MaximumValue="1/1/2100" Type="Date" Text="Invalid Date" Display="Dynamic" />

但它走的是两位数的年份也...
PLZ建议

but it is taking the two digit year also... plz suggest

推荐答案

您可能希望使用一个普通的前pression的日期：

You might want to use a regular expression for the date :

<asp:RegularExpressionValidator ID="dateValRegex" runat="server" ControlToValidate="txtDob" ErrorMessage="Please Enter a valid date in the format (mm/dd/yyyy)" ValidationExpression="^(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d$"></asp:RegularExpressionValidator>

此外，由于丹尼尔指出下面你将需要结合使用这与其他验证，充分验证日期。

Also, as Daniel pointed out below you will need to use this in conjunction with your other validators to fully validate the date.
