Examples
The following code example demonstrates the use of this member.
private void dataGridView1_CellPainting(object sender,
System.Windows.Forms.DataGridViewCellPaintingEventArgs e)
{
if (this.dataGridView1.Columns["ContactName"].Index ==
e.ColumnIndex && e.RowIndex >= 0)
{
Rectangle newRect = new Rectangle(e.CellBounds.X + 1,
e.CellBounds.Y + 1, e.CellBounds.Width - 4,
e.CellBounds.Height - 4);
using (
Brush gridBrush = new SolidBrush(this.dataGridView1.GridColor),
backColorBrush = new SolidBrush(e.CellStyle.BackColor))
{
using (Pen gridLinePen = new Pen(gridBrush))
{
// Erase the cell.
e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
// Draw the grid lines (only the right and bottom lines;
// DataGridView takes care of the others).
e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left,
e.CellBounds.Bottom - 1, e.CellBounds.Right - 1,
e.CellBounds.Bottom - 1);
e.Graphics.DrawLine(gridLinePen, e.CellBounds.Right - 1,
e.CellBounds.Top, e.CellBounds.Right - 1,
e.CellBounds.Bottom);
// Draw the inset highlight box.
e.Graphics.DrawRectangle(Pens.Blue, newRect);
// Draw the text content of the cell, ignoring alignment.
if (e.Value != null)
{
e.Graphics.DrawString((String)e.Value, e.CellStyle.Font,
Brushes.Crimson, e.CellBounds.X + 2,
e.CellBounds.Y + 2, StringFormat.GenericDefault);
}
e.Handled = true;
}
}
}
}
