Hi,

I am getting the following exception in the design view of Expression Blend when I try to view a usercontrol which contains a XamGrid:

AgrumentException: Value does not fall within the expected range.

at Ms.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData_

at MS.Internal.XcpImports.MethodEx(DependencyObject obj, String name)

at MS.Internal.XcpImports.UIElement_UpdateLayout(UIElement element)

Here is my XAML:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:ig="http://schemas.infragistics.com/xaml"
    x:Class="MyGridExample">
    <ig:XamGrid x:Name="MyGrid" DataContext="{Binding}" ItemsSource="{Binding Rows}">
            <ig:XamGrid.Columns>
            <ig:TextColumn Key="Property1">
                <ig:TextColumn.HeaderTemplate>
                    <DataTemplate>
                        <TextBlock Text="Property1" />
                    </DataTemplate>
                </ig:TextColumn.HeaderTemplate>
            </ig:TextColumn>
        </ig:XamGrid.Columns>
        </ig:XamGrid>
</UserControl>

Xaml codebehind:

public partial class MyGridExample : UserControl
    {
        public MyGridExample()
        {
            InitializeComponent();
            DataContext = new GridViewModel();
        }
    }

ViewModel class:

public class GridViewModel
   {
      public ObservableCollection<Row> Rows { get; set; }
      
      public GridViewModel()
      {
         Rows = new ObservableCollection<Row> { new Row { Property1 = "test" }};
      
      }

}

Model:

public class Row
    {
        public string Property1 { get; set; }
    }

I also get a similar exception when opening most of the Grid samples xaml files from the code samples provided in Infragistics.Web.SLLOB.sln; i.e.:ExportToWord.xaml, ExportToWordEvents.xaml, ExportToWordLayoutSettings.xaml, GridDataBinding.xaml, GridViewModel.xaml, HierarchicalData.xaml, ColumnChooser.xaml, ColumnMoving,xaml, ColumnResizing.xaml, ColumnTypeMappings.xaml, ColumnTypes.xaml, ComboBoxColumn.xaml, ConditionalFormattingRules.xaml, DateColumns.xaml, FixedColumns.xaml, GroupColumns.xaml, IDataErrorInfoSupport.xaml, ImageColumns.xaml, RightToLeftSupport,xaml, StringIndexersSupport.xaml, TemplateColumnLayout.xaml, TemplateColumns.xaml, ToolTips.xaml, UnboundColumns.xaml.

Note that the following xaml files in the samples do not exhibit this problem:

DataAnnotations.xaml (this has a different error; Invalid XAML which may be masking the error)

HierarchnicalFinancialData.xml

SelfReferencingData.xml
