        //DataColumn for Name and Address

        DataColumn NameColumn = new DataColumn("Name", typeof(string));
        DataColumn AddColumn = new DataColumn("Address", typeof(string));

        //add Column to Datatable
        dynamicDataTable.Columns.Add(NameColumn);
        dynamicDataTable.Columns.Add(AddColumn);
        //loop for 5 item in DataTable
        for (int i = 0; i < 5; i++)
        {
            dynamicRow = dynamicDataTable.NewRow();
            //Add Rows to dymanicTable
            dynamicDataTable.Rows.Add(dynamicRow);
            //Assign Column value
            dynamicDataTable.Rows[i][NameColumn] = Guid.NewGuid().ToString();
            dynamicDataTable.Rows[i][AddColumn] = = Guid.NewGuid().ToString();
        }

        //Bind DynamicDataTable into a GridView
        GridViewDataShow.DataSource = dynamicDataTable;
       GridViewDataShow.DataBind();
