Set postion of gridview column with autogenerated column

Question

I have a Gridview with autogenerated Column = "true" Now I want to change the postion of gridview column in the gridview's OnRowCreated event.

I use this code

  TableCell cell = e.Row.Cells[1];
  TableCell cell1 = e.Row.Cells[0];
  e.Row.Cells.RemoveAt(1);
  e.Row.Cells.RemoveAt(0);
  e.Row.Cells.Add(cell1);
  e.Row.Cells.Add(cell);

It works fine it moves column 0 and 1 to last positions of grid view

Now I want to move 3rd column of gridview to the first position, so I use

TableCell cell2 = e.Row.Cells[3];
e.Row.Cells.RemoveAt(3);
e.Row.Cells.AddAt(0, cell2);

but it's not working....

If you are binding the GridView to a DataTable , you could move the columns on the DataTable before you bind it to the GridView :

DataTable table = new DataTable();
table.Columns.Add("x");
table.Columns.Add("y");
table.Columns.Add("z");

table.Rows.Add("1", "2", "3");
table.Rows.Add("1", "2", "3");
table.Rows.Add("1", "2", "3");

//Move the column 
table.Columns["z"].SetOrdinal(0);

string value = table.Rows[0][0].ToString();
//Outputs 3

gridView.DataSource = table;
gridView.DataBind();
