ASP.NET

I wanted to validate a date, so i change the the textbox mode from "single" to "date" in asp.net 2012 it worked wonderful in chrome, however, it did not work in IE and firefox.

to make sure that a valid date is entered in IE, firefox and other browsers I added

<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>

it worked fine in IE, and Firefox when entering the date however when I enter a valid date in chrome I am getting the validation error message.

is there are validation for all browsers?

What I have tried:

<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$">
