範例
下列程式碼範例說明如何使用這個屬性。 此範例是How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control中較大型範例的一部分。
// Paints the custom selection background for selected rows.
void dataGridView1_RowPrePaint(object sender,
DataGridViewRowPrePaintEventArgs e)
{
// Do not automatically paint the focus rectangle.
e.PaintParts &= ~DataGridViewPaintParts.Focus;
// Determine whether the cell should be painted
// with the custom selection background.
if ((e.State & DataGridViewElementStates.Selected) ==
DataGridViewElementStates.Selected)
{
// 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);
// Paint the custom selection background.
using (Brush backbrush =
new System.Drawing.Drawing2D.LinearGradientBrush(rowBounds,
this.dataGridView1.DefaultCellStyle.SelectionBackColor,
e.InheritedRowStyle.ForeColor,
System.Drawing.Drawing2D.LinearGradientMode.Horizontal))
{
e.Graphics.FillRectangle(backbrush, rowBounds);
}
}
}
' Paints the custom selection background for selected rows.
Sub dataGridView1_RowPrePaint(ByVal sender As Object, _
ByVal e As DataGridViewRowPrePaintEventArgs) _
Handles dataGridView1.RowPrePaint
' Do not automatically paint the focus rectangle.
e.PaintParts = e.PaintParts And Not DataGridViewPaintParts.Focus
' Determine whether the cell should be painted with the
' custom selection background.
If (e.State And DataGridViewElementStates.Selected) = _
DataGridViewElementStates.Selected Then
' Calculate the bounds of the row.
Dim rowBounds As New Rectangle( _
Me.dataGridView1.RowHeadersWidth, e.RowBounds.Top, _
Me.dataGridView1.Columns.GetColumnsWidth( _
DataGridViewElementStates.Visible) - _

' Paint the custom selection background.
Dim backbrush As New _
System.Drawing.Drawing2D.LinearGradientBrush(rowBounds, _
Me.dataGridView1.DefaultCellStyle.SelectionBackColor, _
e.InheritedRowStyle.ForeColor, _

Try
e.Graphics.FillRectangle(backbrush, rowBounds)
Finally
backbrush.Dispose()
End Try
End If
End Sub
