Contoh

Contoh kode berikut menunjukkan cara menggunakan State properti untuk menentukan apakah baris dipilih. Jika baris dipilih, kode akan melukis latar belakang kustom. Variabel, e, berjenis DataGridViewRowPrePaintEventArgs. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan dalam Cara: Menyesuaikan Tampilan Baris di Kontrol DataGridView Formulir Windows.

// 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);
    }
}

' 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) - _
        Me.dataGridView1.HorizontalScrollingOffset + 1, _
        e.RowBounds.Height)

    ' Paint the custom selection background.
    Dim backbrush As New _
        System.Drawing.Drawing2D.LinearGradientBrush(rowBounds, _
        Me.dataGridView1.DefaultCellStyle.SelectionBackColor, _
        e.InheritedRowStyle.ForeColor, _
        System.Drawing.Drawing2D.LinearGradientMode.Horizontal)
    Try
        e.Graphics.FillRectangle(backbrush, rowBounds)
    Finally
        backbrush.Dispose()
    End Try
End If
