 hai baskaran,


use below code this may helps you

//declare data table globally
private DataTable myTable = new DataTable();
//write these two statements in the constucor
 this.initialiseTable(this.myTable);
 this.GvSellCd.DataSource = this.myTable;
//write this method to add headres to gridview
private void initialiseTable(DataTable table)
        {
            // add all columns
            table.Columns.Add(new DataColumn("CD ID"));
            table.Columns.Add(new DataColumn("Item Name"));
            table.Columns.Add(new DataColumn("Item Description"));
            table.Columns.Add(new DataColumn("Cost"));
            table.Columns.Add(new DataColumn("Quantity"));
            table.Columns.Add(new DataColumn("Amount"));
        }
//write these code click event of radio button
                            DataRow rd = this.myTable.NewRow();
                            // set values
                            rd[0] = txtItemNo.Text;
                            rd[1] = LblItemName.Text;
                            rd[2] = lblItemDescription.Text;
                            rd[3] = lblCdCost.Text;
                            rd[4] = Quantity.ToString();
                            rd[5] = lblCdCost.Text;
                           this.myTable.Rows.Add(rd);
