範例

以下程式碼範例使用導出類別 Panel。 範例中評估文字框的位置，並改變其父容器面板控制項的外觀與行為。 範例要求你建立一個控制點實例 Panel ， TextBox且 Button。 將盒子放在面板上，使其至少重疊於面板的一邊。 只需點擊按鈕即可呼叫此子程序，即可查看面板行為與外觀的差異。

void MySub()
{
   /* If the text box is outside the panel's bounds, 
          turn on auto-scrolling and set the margin. */
   if ( text1->Location.X > panel1->Location.X || text1->Location.Y > panel1->Location.Y )
   {
      panel1->AutoScroll = true;

      /* If the AutoScrollMargin is set to 
                less than (5,5), set it to 5,5. */
      if ( panel1->AutoScrollMargin.Width < 5 || panel1->AutoScrollMargin.Height < 5 )
      {
         panel1->SetAutoScrollMargin( 5, 5 );
      }
   }
}

private void MySub()
 {
    /* If the text box is outside the panel's bounds, 
       turn on auto-scrolling and set the margin. */
    if (text1.Location.X > panel1.Location.X ||
     text1.Location.Y > panel1.Location.Y)
    {
       panel1.AutoScroll = true;
       /* If the AutoScrollMargin is set to 
          less than (5,5), set it to 5,5. */
       if(panel1.AutoScrollMargin.Width < 5 ||
        panel1.AutoScrollMargin.Height < 5)
       {
          panel1.SetAutoScrollMargin(5, 5);
       }
    }
 }

Private Sub MySub()
    ' If the text box is outside the panel's bounds,
    ' turn on auto-scrolling and set the margin. 
    If (text1.Location.X > panel1.Location.X) Or _
        (text1.Location.Y > panel1.Location.Y) Then
        
        panel1.AutoScroll = True            
        ' If the AutoScrollMargin is set to
        ' less than (5,5), set it to 5,5. 
        If (panel1.AutoScrollMargin.Width < 5) Or _
            (panel1.AutoScrollMargin.Height < 5) Then
            
            panel1.SetAutoScrollMargin(5, 5)
        End If
    End If
End Sub

備註

邊界則是設定每個控制點周圍邊框的寬度與高度。 此邊距用來判斷何時需要在容器上放置滾動條，以及當選擇控制項時該捲動到哪裡。
