I use the code of this link 

Edit Update ASP.Net GridView cell value on Click using jQuery 

but the data updated after that user clicks on another cell twice.

I want to update the Mark cell after the user presses the enter button or click on another cell.

the base code that I use doesn't have any problem. but when I use it in my project got this problem.

how can I fix this problem?

based on my project like below:

            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3"
