You can apply date format in RegularExpressionValidator
suppose I have a textbox to apply date time by "dd/MM/yyyy" format.
I can use flowing ValidationExpression:
<asp:RegularExpressionValidator
ID="RegularExpressionValidator2"
runat="server"
ValidationExpression="(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d"
ControlToValidate="myTextBox"
ErrorMessage="Enter date in dd/mm/yyyy format">
