c# - Transferring all data from dataGridView to a textbox -

here question. have restaurant program in customer chooses wishes eat , data displayed in datagridview. example 6 different dishes = 6 different rows each containing name, amount , price. after need print bill, want information datagridview textbox. rows. how can that?

p.s. i've searched lot there information on how transfer currentrow data textbox i've found.

 private void form4_load(object sender, eventargs e)     {         form1 f1 = new form1();         string billinfo = string.empty;         foreach (datagridviewrow row in f1.datagridview1.rows)         {             billinfo = string.format("{0}{1} {2} {3}{4}", billinfo, row.cells["name"].value, row.cells["amount"].value, row.cells["price"].value, environment.newline);         }         textbox1.text = billinfo;     } 

just loop through each row , format column values string, adding system.environment.newline seperating entries in textbox.

string billinfo = string.empty;  foreach (datagridviewrow row in this.datagridview1.rows) {   billinfo = string.format("{0}{1} {2} {3}{4}", billinfo, row.cells["name"].value, row.cells["amount"].value, row.cells["price"].value, environment.newline); }  this.textbox1.text = billinfo;
