ColumnAutoSizing プロパティ

ユーザーがヘッダーの調整可能の領域をダブルクリックしたときに、ColumnWidth プロパティの値が PrimaryIntervalにとって理想的な幅に設定されるかどうかを示す値を取得または設定します。

シンタックス

Visual Basic

'宣言
 
Public Property ColumnAutoSizing As TimelineViewColumnAutoSizing

C#

public TimelineViewColumnAutoSizing ColumnAutoSizing {get; set;}

解説

注: ColumnSizing プロパティを None または Column に設定した場合は、ColumnAutoSizing プロパティが無効です。ユーザーは列のサイズを自動的に変更できるのにヘッダーのサイズ変更を有効にする必要があります。
