Hi, You no need to save the grid view. The data is stored in the data table and which binded with the gridview control. You need to iterate the datatable and insert the record into sql server. foreach (DataRow drow in ds.Tables[0].Rows) { string col1 = drow[0].ToString(); string col2 = drow[1].ToString(); string col3 = drow[2].ToString(); string col4 = drow[3].ToString(); string col5 = drow[4].ToString(); string _sqlInsert = "INSERT INTO Table1(column1,column2,column3,column4,column5) VALUES('"+col1+"','"+col2+"','"+col3+"','"+col4+"','"+col5+"')"; }
