Sorting throws exception after upgrading to latest

[Gary]

I'm trying to update my project to use the latest release (2009.2 813), but when I sort on any column, I get this exception:

{"Invalid property or field - 'colDescription' for type: Object"}

Hi Gary,

Can you send us small example which demonstrates your scenario and this issue can be reproduced?

Here's a simple page and code behind which demonstrates the problem.  Our application defines an empty datasource, which is then populated by application code when a button is clicked.  The problem seems to be that with the latest telerik version, an empty initial datasource causes issues with sorting.  Here's the xaml for the test page:

<Window x:Class="SortRepro.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="Window1" Height="300" Width="300">

    <Grid>

        <telerik:RadGridView x:Name="SortTestGrid" AutoGenerateColumns="False">

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn Header="Click To Sort" DataMemberPath="TestCol"></telerik:GridViewDataColumn>

            </telerik:RadGridView.Columns>

        </telerik:RadGridView>

    </Grid>

</Window>

Here's the code behind.  When you bring up the window, sort on the column, you should get an exception.  Note the commented out line in GetDS, if you uncomment this, sorting will work as expected.  This same code works with previous versions of the grid:

using System;

using System.Windows;

using System.Data;

namespace SortRepro

{

    /// <summary>

    /// Interaction logic for Window1.xaml

    /// </summary>

    public partial class Window1 : Window

    {

        public Window1()

        {

            InitializeComponent();

            this.SortTestGrid.ItemsSource = this.GetDS();

            this.Loaded += new RoutedEventHandler(Window1_Loaded);

        }

        void Window1_Loaded(object sender, RoutedEventArgs e)

        {

            DataView dv = this.SortTestGrid.ItemsSource as DataView;

            dv.Table.Rows.Add(new Object[] { "bar" });

        }

        private DataView GetDS()

        {

            DataSet ds = new DataSet();

            DataTable dt = new DataTable();

            DataColumn col1 = new DataColumn();

            col1.Caption = "TestCol";

            col1.ColumnName = "TestCol";

            dt.Columns.Add(col1);

            ds.Tables.Add(dt);

            //if you uncomment this line, sorting works

            //dt.Rows.Add(new Object[] { "foo" });

            return dt.DefaultView;

        }

    }

}

Thanks for your help.

Hi Gary,

The issue is already fixed and the fix will be available in our latest internal build (this Friday). I've attached small demo application demonstrating your case with our latest binaries.

All the best,

We build our own telerik binaries from your source (we've made some modifications).  Is there anyway to get internal build sources, I only see the option to download binaries.  Or perhaps there's a workaround I can apply until the next official release?

[Hristo]

Hi Gary,

I transferred your forum post to a regular support ticket. You can download the source code for our latest internal (2009_2_904) from Your Account-> Downloads->RadControls for WPF->Latest internal builds->RadControls_2009_2_904_Source.zip. Download it, give it a try and let me know how it goes.

Please not that the source code will be available till Monday (Sept 7).

Sincerely yours,
Hristo
