Сохраните данные Gridview кнопкой, а затем снова загрузите его?

Question

Я хочу сохранить поле Gridview одним щелчком мыши. Можно ли получить все данные?

Вещи, которые я попробовал

      var rowIndex = row.rowIndex - 1; 
      alert("row: " + rowIndex); 
      return false; 
     }

Можно ли принимать изменения решения от яваскрипта и сохранить его с главной страницы ..

Answer 1

Вы можете зациклить строки и получить поле адреса для каждой строки.

foreach (GridViewRow row in GridView1.Rows) 
{ 
    string address = row.Cells[2].Text; 
    string name = row.Cells[1].Text; 

    //Update your DB here 
}
