示例1: dataGridView1_RowPostPaint
// 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) -

e.RowBounds.Height);
SolidBrush forebrush = null;

// Determine the foreground color.

// columns, adjusting for the horizontal scrolling position
// and the current row height, and displaying only whole
