DataGridViewColumn.HeaderText Property

This property is useful only when the column has an associated header cell. For more information, see the HeaderCellCore property.

Note
There is no corresponding header text property for rows. To display labels in row headers, you must handle the DataGridView.CellPainting event and paint your own labels when DataGridViewCellPaintingEventArgs.ColumnIndex is -1.

The following code example uses the HeaderText property to change the text in the column header. This code example is part of a larger example provided for the DataGridViewColumn class.

// Change the text in the column header. 
private void Button9_Click(object sender,
    EventArgs args)
{
    foreach (DataGridViewColumn column in dataGridView.Columns)
    {

        column.HeaderText = String.Concat("Column ",
            column.Index.ToString());
    }
}
