Column Filter not showing up

[Boots]

Hello,

I ran into a problem when adding a columns thru code. It seemed to work fine in the 2009 Q3 Beta 1 version. basically i'm adding the columns in codebehind then later on i'm adding data to the grid. When I do that the filters dont show up on the Column Headers.

here is some sample code.

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    Title="Group Chart Test">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="30" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <telerik:RadGridView Name="rgv"
                             AutoGenerateColumns="False"
                             Grid.Row="0"
                             Grid.ColumnSpan="2"/>

        <Button Click="Button_Click"
                Grid.Row="1"
                Grid.Column="0"
                Content="Add Columns"/>
        <Button Click="Button_Click_1"
                Grid.Row="1"
                Grid.Column="1"
                Content="Add Items"/>
    </Grid>
</Window>

public partial class Window1 : Window
    {

        ArrayList arrayList = new ArrayList();
        public Window1()
        {
            try
            {

                InitializeComponent();

                for (int i = 0; i < 100; i++)
                {
                    arrayList.Add(new myObject()
                    {
                        Year = 2002,
                        Quarter = "First",
                        Make = "Chevrolet",
                        Sales = 1000
                    });
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            rgv.Columns.Add(new GridViewDataColumn()
            {
                UniqueName = "Year",
                Header = "Year"
            });

            rgv.Columns.Add(new GridViewDataColumn()
            {
                UniqueName = "Quarter",
                Header = "Quarter"
            });

            rgv.Columns.Add(new GridViewDataColumn()
            {
                UniqueName = "Make",
                Header = "Make"
            });

            rgv.Columns.Add(new GridViewDataColumn()
            {
                UniqueName = "Sales",
                Header = "Sales"
            });
        }

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            rgv.ItemsSource = arrayList;
        }
    }

    class myObject
    {
        public int Year { get; set; }
        public String Quarter { get; set; }
        public String Make { get; set; }
        public double Sales { get; set; }
    }

if I set the DataType of the column the filters show up. Not sure if its a bug or not but thought i would ask.

Thanks Again,
Boots

Hello Again,

I also noticed if I create the columns in xaml the filters dont show up unless I add the DataType to the column. I ran into somthing else with the grid. The aggregates arent showing up on the Column Footers.
