ASP.Net C# and JavaScript textfield expiration date -

-

i looking textbox user can enter expiration date his/her license. user can enter expiration date between today's date , 12/31/2099.

this have now:

function rangevalidation(dt)         {             var startrange = new date(date.parse("12/02/1900"));             var endrange = new date(date.parse("12/31/2099"));             var lblmesg = document.getelementbyid("<%=lblmesg.clientid%>") ;             if (dt<startrange || dt>endrange)             {                 lblmesg.style.color="red";                 lblmesg.innerhtml = "date should between 12/01/2014 , 12/31/2099";             }         }      <asp:textbox id="txtrange" runat="server" maxlength = "10" onkeyup = "validatedate(this, event.keycode)" onkeydown = "return dateformat(this, event.keycode)"></asp:textbox>

is there easier way that? running date issues, exampele dd/mm/yyyy , on, simple in asp.net (i don't prefer using javascript cause not familiar it)

thanks.
