Solution 1

//Try this
 Table table = new Table();
            table.BorderStyle = BorderStyle.Solid;
            table.BorderWidth=new Unit(1);
            table.BorderColor = System.Drawing.Color.Black;
            table.GridLines = GridLines.Both;

//You can also render the GridView directly

thanks for support.
But this code is for lines between data not for all gridlines in excel sheet.
I want to show gridline in whole sheet.
