'宣言
 
Public Property FilterClearButtonLocation As FilterClearButtonLocation

C#

public FilterClearButtonLocation FilterClearButtonLocation {get; set;}

解説

FilterClearButtonLocation プロパティは、フィルター クリア ボタンの表示のおよび位置を指定します。デフォルトでは、フィルター クリア ボタンはフィルター レコードのレコード セレクターおよび各フィルター セルに表示されます。それによって、ユーザーはフィルター条件をクリアすることが可能です。

FieldSettings の FieldSettings.FilterClearButtonVisibility プロパティを使用して、フィールド単位でフィルター クリア ボタンの可視性を制御できます。

フィルターのクリアなど、フィルターを操作するには、RecordFilterCollection を使用します。

使用例

The following code snippet sets FilterClearButtonLocation to RecordSelectorAndFilterCell and FilterClearButtonVisibility of 'Country' field to Collapsed. This will result in all fields displaying filter clear button in their filter cells except the 'Country' field.

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)
        
        ' Enable the record filtering functionality.
        _dp.FieldSettings.AllowRecordFiltering = True

        ' You can use FilterClearButtonLocation to specify whether to display filter clear
        ' button in record selector and/or cells. Note that the filter clear button is 
        ' displayed only if there are active filters. Therefore you must select some filter
        ' criteria in the filter cell to display the filter clear button.
        _dp.FieldLayoutSettings.FilterClearButtonLocation = FilterClearButtonLocation.RecordSelectorAndFilterCell

        ' You can use the FieldSettings' FilterClearButtonVisibility to override filter 
        ' clear button visibility on a specific field, in this case the 'Country' field.
        _dp.FieldLayouts(0).Fields("Country").Settings.FilterClearButtonVisibility = Visibility.Collapsed

    End Sub
