Hi Gopi.MCA,
According to your description, I think you could try to use Moment.js to verify the date format of the value in the text box.
A simple example:
<head runat="server"> <title></title> <script src="Scripts/jquery-3.5.1.min.js"></script> <script src="Scripts/moment.min.js"></script> <script> function change() { console.log(moment($('#date').val(), 'DD-MMM-YYYY', true).isValid()); //do something here } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:TextBox runat="server" ID="date" onchange="change()"></asp:TextBox> </div> </form> </body>
Result:
Hope this can help you.
Best regards,
