Answer 1

You can do it as follows:

gv.HeaderRow.Cells[i].Text

Or like this:

gv.Rows[0].Cells[i].Text

Lines [0] should be your title bar.

Answer 2

//// Header column names
int gridViewCellCount = yourGridView.Rows[0].Cells.Count;
// string array to hold grid view column names.
string[] columnNames = new string[gridViewCellCount];

for (int i = 0; i < gridViewCellCount; i++)
{
    columnNames[i] = ((System.Web.UI.WebControls.DataControlFieldCell)(yourGridView.Rows[0].Cells[i])).ContainingField.HeaderText;
}

Answer 3

 GridView1.Rows[0].Cells[0].Text;

, ,

  foreach (GridViewRow r in GridView1.Rows)
    {
        string s = r.Cells[0].Text;
        string y = r.Cells[1].Text;
    }

:

  foreach (TableCell Tc in GridView1.HeaderRow.Cells)
    {
        //if you are not getting value than find childcontrol of TabelCell.
        string sssb = Tc.Text;
        foreach (Control ctl in Tc.Controls)
        {

            //Child controls
            Label lb = ctl as Label;
            string s = lb.Text;
        }
    }

    Dim intValCount As Integer = Integer.Parse(e.NewValues.Count)

        Dim i As Integer = 0
        For i = 0 To intValCount - 1
            If Not e.OldValues(i).Equals(e.NewValues(i)) Then

                Sys.Audits.General(intID, "the_database_table", <the table field by index(i)>, e.OldValues(i).ToString, e.NewValues(i).ToString)
            End If
            i += 1
        Next

Answer 6

Its easy: here I read the gridview header text for each header cell and added them as new columns to the data table.

DataTable dt = new DataTable();
foreach(DataControlFieldHeaderCell column in yourGridview.HeaderRow.Cells)
{
  dt.Columns.Add(column.Text.Trim().Replace(" ", ""));                           
}

//Make sure you do all this after yourGridview.DataBind(); 
//If you do not want to bind data first simply bind an empty list like so:
/* yourGridview.DataSource = new List<string>();
   yourGridview.DataBind(); */
