ReevaluateFiltersOnDataChange プロパティ

セル データが変更するときにレコード フィルターを再評価するかどうかを指定します。デフォルトは True に解決されます。

'宣言
 
Public Property ReevaluateFiltersOnDataChange As Nullable(Of Boolean)

C#

public Nullable<bool> ReevaluateFiltersOnDataChange {get; set;}

解説

レコードのデータが変更する場合、デフォルトでデータ プレゼンターはフィルターを再評価します。セル データの変更時に （ユーザー入力によるデータの変更、またはデータ プレゼンター オブジェクト モデルか直接データ ソースからコードでの変更を含む) に実行します。この動作が起こらないようにするには、ReevaluateFiltersOnDataChange プロパティを False に設定します。ただし、フィルター条件を変更する場合は、レコード フィルターを再評価します。

使用例

The following code shows some of the properties and methods available to control the behavior regarding when filters are applied to records.

Visual Basic

Imports Infragistics.Windows
Imports Infragistics.Windows.Controls
Imports Infragistics.Windows.Editors
Imports Infragistics.Windows.DataPresenter
Imports Infragistics.Windows.DataPresenter.Events

    Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
        
        ' FilterEvaluationTrigger controls when the filters are applied to records 
        ' when the user modifies the filter condition.
        _dp.FieldSettings.FilterEvaluationTrigger = FilterEvaluationTrigger.OnEnterKeyOrLeaveCell

        ' ReevaluateFiltersOnDataChange specifies whether to re-evaluate filters on
        ' a record whose data is changed. Default is true. If you set it to false,
        ' you can manually re-evaluate filters on all records using 
        ' RecordFilterCollection's Refresh method.
        _dp.FieldLayoutSettings.ReevaluateFiltersOnDataChange = False

    End Sub

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
        ' Typically calling this method is not necessary as the data presenter 
        ' re-evaluates filters on records whenever data changes. However if you 
        ' set the ReevaluateFiltersOnDataChange to false then you can use this 
        ' method to re-filter records.
        _dp.FieldLayouts(0).RecordFilters.Refresh()

        ' You can also re-evaluate filters on a specific data record by calling
        ' its RefreshFilters method.
        _dp.RecordManager.Sorted(0).RefreshFilters()
    End Sub
