I am setting GridViewDataControl.ItemsSource to an instance of a QueryableCollectionView. When the grid is rendered on the screen I get an AmbiguousMatchException. Any ideas what might cause this?

I have included the stack trace below:

System.Reflection.AmbiguousMatchException was unhandled by user code

  HResult=-2147475171

  Message=Ambiguous match found.

  Source=mscorlib

We used to have such issue before, but it has already been resolved. Could you clarify which version you are working with?

Hi Albert,

Tha StackTrace of the issue we had was exactly the same and was reproducible only when there are more than one DataAnnotations attributes added. Is that your case or is there something more specific ? 

All the best,

This appears to be a bug with the RadGridView. It occurs when you have a column named "Item".

Is there a work-around or fix available?

Kind Regards,
Albert

I have a simple project that demonstrates the problem, but I am not able to access Telerik's Support Ticketing System as it is down at the moment... Here are some code snippets:

MainWindow.xaml:

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

        x:Class="ItemColumnBug.MainWindow"
        Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button Content="PopulateWithItemColumn" Click="PopulateWithItemColumn_Click" />
<Button Grid.Row="1" Content="PopulateWithItemXXXColumn" Click="PopulateWithItemXXXColumn_Click" />
<telerik:RadGridView x:Name="RadGridView" Grid.Row="2"/>
</Grid>
</Window>


MainWindow.xaml.cs:

using System.Data;
using System.Linq;
using System.Windows;
using Telerik.Windows.Data;

namespace ItemColumnBug
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}

private void PopulateWithItemColumn_Click(object sender, RoutedEventArgs e)
{
LoadGrid("Item");
}

private void PopulateWithItemXXXColumn_Click(object sender, RoutedEventArgs e)
{
LoadGrid("ItemXXX");
}

private void LoadGrid(string columnName)
{
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn(columnName, typeof(string)));

DataRow newRow = dt.NewRow();
newRow[columnName] = "hello";
dt.Rows.Add((newRow));

newRow = dt.NewRow();
newRow[columnName] = "there";
dt.Rows.Add((newRow));

RadGridView.ItemsSource = dt;
}
}
}

Hello Albert,

Indeed, you are right - there is such an exception being thrown when you bind to a property named "Item". The thing is that the DataRow object has properties with name "Item" and when we try to invoke the GetProperty() method, it throws the exception. You can prove that with the following code:

DataTable dt = new DataTable();
          DataRow newRow = dt.NewRow();
          var hasItemProperty = newRow.GetType().GetProperties().Any(p => p.Name == "Item");
          var itemProperties = newRow.GetType().GetProperties().Where(p => p.Name == "Item");
          var count = itemProperties.Count();

The count of the items will be 6 in this case.
Nevertheless, I will handle the exception internally so that it is not thrown directly in release mode. Still, my recommendation would be to name your properties so that there is no confustion with default ones - like Item, Column, DataRow for example.
Anyway, thank you for the information and cooperation. I have updated your telerik points accordingly. Let me know if you have any further problems.

Maya

I have the same problem with the RadPropertyGrid of WPF Q3 2013, I'm trying to do a binding to a "Value" property of my object


           propDef = new PropertyDefinition()
                    {
                        DisplayName = arg.Name.Value,
                        Description = arg.Description.Value,
                        Binding = new Binding()
                        {
                            Source = arg,
                            Path = new PropertyPath("Value", null) 
                           
                        },
                       
                        EditorTemplate = this.argTemplateSelector.SelectTemplate(arg, this.PropertyGrid)
                    }

but when the PropertyGrid is rendered on the screen I get an AmbiguousMatchException.

Hi,

Your question is not related to RadGridView, so I would suggest you to post such questions in the respective forum category.

As to your particular case, have you referenced assemblies built against .NET Framework 4.0 or against .NET Framework 4.5? Would it also be possible for you to send us a sample project demonstrating the issue?
