[Solved] Column filtering problem

[Ryan Morgan]

Filter drop down is empty when I set ItemsSource from xaml.

Here is simplified sample:

 

    public class Item
    {
        public string Title
        {
            get;
            set;
        }
    }

    public class AppContext
    {
        private static AppContext _instance = new AppContext();
        private ObservableCollection<Item> _items = new ObservableCollection<Item>();

        public static AppContext Instance
        {
            get
            {
                return _instance;
            }
        }

        public ObservableCollection<Item> Items
        {
            get
            {
                _items.Add(new Item() { Title = "New Item" });
                return _items;
            }
            set
            {
                _items = value;
            }
        }
    }

Startup page xaml:

<UserControl x:Class="SilverlightApplication1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:local="clr-namespace:SilverlightApplication1"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:grid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">

    <UserControl.Resources>
        <local:AppContext x:Key="AppContext"/>
    </UserControl.Resources>

  <Grid x:Name="LayoutRoot">
        <grid:RadGridView x:Name="radGrid" AutoGenerateColumns="False" ItemsSource="{Binding Items, Source={StaticResource AppContext}}">
            <grid:RadGridView.Columns>
                <grid:GridViewDataColumn Header="Title" DataMemberBinding="{Binding Title}"/>
            </grid:RadGridView.Columns>
        </grid:RadGridView>
  </Grid>
</UserControl>

Hi Vlad,

Thanks, for your feedback.

Version i'm using is Q2 SP1.
But I tried Q3 beta and it works fine. Seems it is already fixed in the latest.

Thanks, Ryan
