SummaryDescriptionMaskInGroupBy プロパティ

集計レコードのヘッダーに何を表示するかを指定します。

シンタックス

Visual Basic

'宣言
 
Public Property SummaryDescriptionMaskInGroupBy As String

C#

public string SummaryDescriptionMaskInGroupBy {get; set;}

解説

詳細は SummaryDescriptionMask を参照してください。

明示的に設定されない場合、このプロパティは "[GROUP_BY_VALUE] の集計" として解決されます。

注： 集計レコード ヘッダーを非表示にするには、FieldLayoutSetting の FieldLayoutSettings.SummaryDescriptionVisibility プロパティを使用します。

使用例

Visual Basic

Imports Infragistics.Windows
Imports Infragistics.Windows.Editors
Imports Infragistics.Windows.DataPresenter

    Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
        _dp.DataSource = _dataSource

        ' By default summary records are displayed only at top level and not within nested
        ' group-by records. To demonstrate SummaryDescriptionMaskInGroupBy property, which applies
        ' to summary records inside nested group-by records, we need display summaries in nested 
        ' group-by records by setting SummaryDisplayArea to a value that doesn't contain 
        ' TopLevelOnly.
        ' 
        _dp.FieldSettings.SummaryDisplayArea = SummaryDisplayAreas.Bottom

        Dim fieldLayout As FieldLayout = _dp.FieldLayouts(0)

        ' Note that you actually have to set SummaryDescriptionVisibility, which we do further below, 
        ' to actually show the summary description.
        fieldLayout.SummaryDescriptionMask = "Grand Summaries"
        fieldLayout.SummaryDescriptionMaskInGroupBy = "Summaries for [GROUP_BY_VALUE]"

        ' Set SummaryDescriptionVisibility to actually show the summary description.
        fieldLayout.Settings.SummaryDescriptionVisibility = Visibility.Visible

        ' Add a summary - without at least one summary, the summary record will not be displayed.
        fieldLayout.SummaryDefinitions.Add(SummaryCalculator.Sum, "Price")

    End Sub
