備註

SuspendPaint和ResumePaint方法可用於使用串聯方式隱藏多個Paint時您正在調整圖形的多個屬性的事件。例如，您通常會呼叫SuspendPaint方法，設定Size， Location， BorderColor，或BorderStyle的圖形，然後呼叫屬性ResumePaint方法，讓變更生效。

範例

下列範例示範如何使用SuspendPaint和ResumePaint方法OvalShape控制項。此範例中您需要OvalShape名 OvalShape1 為表單上的控制項。

Private Sub OvalShape1_Click() Handles OvalShape1.Click
    ' Suspend painting.
    OvalShape1.SuspendPaint()
    ' Set some properties.
    OvalShape1.BackStyle = PowerPacks.BackStyle.Opaque
    OvalShape1.BackColor = Color.Blue
    OvalShape1.FillStyle = PowerPacks.FillStyle.Plaid
    OvalShape1.FillColor = Color.Red
    ' Resume painting and execute any pending requests.
    OvalShape1.ResumePaint(True)
End Sub

private void ovalShape1_Click(System.Object sender, System.EventArgs e)
{
    // Suspend painting.
    ovalShape1.SuspendPaint();
    // Set some properties.
    ovalShape1.BackStyle = BackStyle.Opaque;
    ovalShape1.BackColor = Color.Blue;
    ovalShape1.FillStyle = FillStyle.Plaid;
    ovalShape1.FillColor = Color.Red;
    // Resume painting and execute any pending requests.
    ovalShape1.ResumePaint(true);
}
