DataGridViewRow.Cells Property

If the row does not contain any cells when this property is accessed, a new empty DataGridViewCellCollection will be created by a call to the CreateCellsInstance method.

The following code example uses the Cells property to set the value of a cell in the row. This code example is part of a larger code example provided in How to: Manipulate Rows in the Windows Forms DataGridView Control.

// Give cheescake excellent rating. 
private void Button8_Click(object sender,
    System.EventArgs e)
{
    UpdateStars(dataGridView.Rows[4], "******************");
}

int ratingColumn = 3;

private void UpdateStars(DataGridViewRow row, string stars)
{

    row.Cells[ratingColumn].Value = stars;

    // Resize the column width to account for the new value.
    row.DataGridView.AutoResizeColumn(ratingColumn, 
        DataGridViewAutoSizeColumnMode.DisplayedCells);
}
