MinimumColumnResizeWidth プロパティ

サイズ変更の操作時の ColumnWidth プロパティの変更可能な最小値を取得または設定します。

シンタックス

Visual Basic

'宣言
 
Public Property MinimumColumnResizeWidth As Integer

C#

public int MinimumColumnResizeWidth {get; set;}

例外

例外	解説
System.ArgumentOutOfRangeException	値は 0 以下だ場合は発生します。

解説

MinimumColumnResizeWidth は、列ヘッダー (および時間帯) が定義した値以下にサイズ変更できないようにします。たとえば、このプロパティは列が最適なサイズ以下にサイズ変更できないように、PerformColumnAutoResize プロパティを呼び出したあとに ColumnWidthResolved プロパティの値を設定できます。
