Q082. XamDataGrid でフィルタリングの初期値を設定するには？

A．RecordFilter の新しいインスタンスを作成し、FieldLayout.RecordFilters に追加します。

以下、サンプルです。このサンプルでは nameフィールドのフィルタリング条件を「等しい」にし、初期値を「佐藤 陽一」に設定してます。

C#

using System;
using System.Windows;
using Infragistics.Windows.Controls;
using Infragistics.Windows.DataPresenter;

namespace WpfApplication1 {
	public partial class MainWindow : Window {
		public MainWindow() {
			InitializeComponent();
		}

		private void Window_ContentRendered(object sender, EventArgs e) {
			var filter = new RecordFilter();
			filter.FieldName = "name";
			filter.Conditions.Add(new ComparisonCondition(ComparisonOperator.Equals, "佐藤 陽一"));
			this.xamDataGrid1.FieldLayouts[0].RecordFilters.Add(filter);
		}
	}
}

VB.NET

Imports Infragistics.Windows.Controls
Imports Infragistics.Windows.DataPresenter

Public Class MainWindow
	Inherits Window

	Private Sub Window_ContentRendered(sender As System.Object, e As System.EventArgs) Handles Me.ContentRendered
		Dim filter = New RecordFilter()
		filter.FieldName = "name"
		filter.Conditions.Add(New ComparisonCondition(ComparisonOperator.Equals, "佐藤 陽一"))
		Me.xamDataGrid1.FieldLayouts(0).RecordFilters.Add(filter)
	End Sub
End Class
