Answer 1

Here's a few utilities I wrote years ago that may help you:

// ---- GetCellByName ----------------------------------
//
// pass in a GridViewRow and a database column name 
// returns a DataControlFieldCell or null

static public DataControlFieldCell GetCellByName(GridViewRow Row, String CellName)
{
    foreach (DataControlFieldCell Cell in Row.Cells)
    {
        if (Cell.ContainingField.ToString() == CellName)
            return Cell;
    }
    return null;
}

// ---- GetColumnIndexByHeaderText ----------------------------------
//
// pass in a GridView and a Column's Header Text
// returns index of the column if found 
// returns -1 if not found 

static public int GetColumnIndexByHeaderText(GridView aGridView, String ColumnText)
{
    TableCell Cell;
    for (int Index = 0; Index < aGridView.HeaderRow.Cells.Count; Index++)
    {
        Cell = aGridView.HeaderRow.Cells[Index];
        if (Cell.Text.ToString() == ColumnText)
            return Index;
    }
    return -1;
}

// ---- GetColumnIndexByDBName ----------------------------------
//
// pass in a GridView and a database field name
// returns index of the bound column if found 
// returns -1 if not found 

static public int GetColumnIndexByDBName(GridView aGridView, String ColumnText)
{
    System.Web.UI.WebControls.BoundField DataColumn;

    for (int Index = 0; Index < aGridView.Columns.Count; Index++)
    {
        DataColumn = aGridView.Columns[Index] as System.Web.UI.WebControls.BoundField;

        if (DataColumn != null)
        {
            if (DataColumn.DataField == ColumnText)
                return Index;
        }
    }
    return -1;
}
