範例

下列程式碼範例說明此方法的使用方式。 此範例是如何：擴充其行為和外觀，以自訂 dataGridView 控制項中Windows Forms儲存格和資料行中較大型範例的一部分。

// Force the cell to repaint itself when the mouse pointer enters it.
protected override void OnMouseEnter(int rowIndex)
{
    this.DataGridView.InvalidateCell(this);
}

// Force the cell to repaint itself when the mouse pointer leaves it.
protected override void OnMouseLeave(int rowIndex)
{
    this.DataGridView.InvalidateCell(this);
}

' Force the cell to repaint itself when the mouse pointer enters it.
Protected Overrides Sub OnMouseEnter(ByVal rowIndex As Integer)
    Me.DataGridView.InvalidateCell(Me)
End Sub

' Force the cell to repaint itself when the mouse pointer leaves it.
Protected Overrides Sub OnMouseLeave(ByVal rowIndex As Integer)
    Me.DataGridView.InvalidateCell(Me)
End Sub

備註

這個方法類似于 DataGridView.OnCellMouseLeave 方法。 它會在引發事件的相同情況下 DataGridView.CellMouseLeave 呼叫，但實際上不會引發事件。
