CellActivation プロパティ

アクティベートされた時にオブジェクトがどのように動作するかを決定する値を返すか設定します。

シンタックス

Visual Basic

public Activation CellActivation {get; set;}

C#

'宣言
 
Public Property CellActivation As Activation

 

解説

UltraGridCell オブジェクトの Activation プロパティは、セルを含む UltraGridRow オブジェクトおよび UltraGridColumn オブジェクトの Activation プロパティの設定に従います。セルの行または列の Activation プロパティが False に設定されている場合は、セル自体の Activation の設定にかかわらず、セルはアクティブ化できません。他の親型の設定も影響しません。つまり、セルは行の Activation が False に設定されている場合、その列の設定にかかわらず非アクティブとなります。
