I am not able to select date before the year of 2000. I also used masked extender becoz i wanted masking in textbox. Below i have attached code which i have tried
<asp:TextBox ID="txtOrientationDate" runat="server" onclick="this.focus();this.select()" AutoCompleteType="None" MaxLength="10" ValidateRequestMode="Inherit" width="90px" TabIndex="450" cssclass="textbox"></asp:TextBox>
<asp:RegularExpressionValidator runat="server" ControlToValidate="txtOrientationDate" ValidationExpression="^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]\d)\d{2}|0?2/29/((19|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$"
ErrorMessage="Invalid date format." ForeColor="Red" ValidationGroup="Group1" />
<ajax:CalendarExtender ID="CalendarExtender2" TargetControlID="txtOrientationDate" Format="MM/dd/yyyy" runat="server" >
