How do I get/set the cell value of a DataGrid like in the image.

I want to get the text from the textbox in the cell and use it in a save command.

Here is my current code:
c#.net Code:
  1. protected void grid_ItemCommand(object source, DataGridCommandEventArgs e)

  2.     {

  3.         // stop editing

  4.         GV.EditItemIndex = -1;

  5.  
  6.         switch (e.CommandName)

  7.         {

  8.             case "Insert":

  9.                 break;

  10.             case "Update":

  11.                 string a = "";

  12.                 

  13.               a = e.Item.Cells[1].Text;

  14.                             

  15.                

  16.                 break;

  17.             case "Cancel":

  18.                 EditCommandColumn ecc = (EditCommandColumn)GV.Columns[0];

  19.                 ecc.UpdateText = "Update";

  20.                 break;

  21.             case "Edit":

  22.                 // begin editing

  23.                 GV.EditItemIndex = e.Item.ItemIndex;

  24.                 break;

  25.         }

That code is returning blank strings. Please help me get my cell values.
