I have set column filter programmaticaly. It does filters the view.
When I click the funnel icon - the default filtering control does not reflect filtering condition.
using System.Collections.Generic;
using System.Windows;
using Telerik.Windows.Data;
namespace TestGridViewFilter
{
public partial class MainPage
{
public MainPage()
{
Documents.Add(new Document { Title = "T1", State = State.Returned });
Documents.Add(new Document { Title = "T2", State = State.Draft });
Documents.Add(new Document { Title = "T3", State = State.Final });
Documents.Add(new Document { Title = "T4", State = State.InReview });
Documents.Add(new Document { Title = "T5", State = State.New });
Documents.Add(new Document { Title = "T6", State = State.Submitted });
Documents.Add(new Document { Title = "T7", State = State.Withdrawn });
InitializeComponent();
}
private void SetFilters()
{
TestGridView.FilterDescriptors.SuspendNotifications();
TestGridView.FilterDescriptors.Clear();
var statusFilterDescriptor = new CompositeFilterDescriptor();
statusFilterDescriptor.FilterDescriptors.Add(
new FilterDescriptor("State", FilterOperator.IsEqualTo, State.Final));
statusFilterDescriptor.FilterDescriptors.Add(
new FilterDescriptor("State", FilterOperator.IsEqualTo, State.Withdrawn));
statusFilterDescriptor.LogicalOperator = FilterCompositionLogicalOperator.Or;
TestGridView.FilterDescriptors.Add(statusFilterDescriptor);
TestGridView.FilterDescriptors.ResumeNotifications();
}
private List<Document> _documents;
public List<Document> Documents
{
get { return _documents ?? (_documents = new List<Document>()); }
}
private void TestGridViewDistinctValuesLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDistinctValuesLoadingEventArgs e)
{
e.ItemsSource = TestGridView.GetDistinctValues(e.Column, false);
}
private void UserControlLoaded(object sender, RoutedEventArgs e)
{
SetFilters();
}
}
public class Document
{
public State State { get; set; }
public string Title { get; set; }
}
public enum State
{
New,
