SizingMode プロパティ

パネルのサイズ変更方法を取得または設定します。
シンタックス
'宣言
 
Public Property SizingMode As PanelSizingMode
public PanelSizingMode SizingMode {get; set;}
解説

パネルは 4 つのサイズ モードをサポートします。

サイズ設定モード
Automatic 幅はコンテンツに基づきます (AutoSizeWidth)
Adjustable Width は現在のサイズを決定しますが、パネルは、パネルの右端をドラッグしてエンドユーザーがサイズ変更できます。
Fixed Width プロパティが使用されます。
Spring それぞれの表示可能なパネルにスペースを割り当てた後に使用できる領域は、Spring サイズのモード パネルすべてに配分されます。

一部のパネル スタイル (つまり、Progress、ControlContainer および MDIList) では Automatic は無効で計算できません。
