Ejemplos

En el ejemplo de código siguiente se muestra cómo usar la RowBounds propiedad para determinar los límites de las celdas visibles de una fila. Este ejemplo de código forma parte de un ejemplo más grande que se proporciona en How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control.

// Paints the content that spans multiple columns and the focus rectangle.
void dataGridView1_RowPostPaint(object sender,
    DataGridViewRowPostPaintEventArgs e)
{
    // Calculate the bounds of the row.
    Rectangle rowBounds = new Rectangle(
        this.dataGridView1.RowHeadersWidth, e.RowBounds.Top,
        this.dataGridView1.Columns.GetColumnsWidth(
            DataGridViewElementStates.Visible) -
        this.dataGridView1.HorizontalScrollingOffset + 1,
        e.RowBounds.Height);

    SolidBrush forebrush = null;
    try
    {
        // Determine the foreground color.
        if ((e.State & DataGridViewElementStates.Selected) ==
            DataGridViewElementStates.Selected)
        {
            forebrush = new SolidBrush(e.InheritedRowStyle.SelectionForeColor);
        }
        else

        object recipe =
            this.dataGridView1.Rows.SharedRow(e.RowIndex).Cells[2].Value;

            // columns, adjusting for the horizontal scrolling position

El ancho de la RowBounds propiedad es el mismo que el ancho de DataGridView. Para obtener el ancho de las columnas de DataGridView, use el GetColumnsWidth método .
