Ambiguous Reference for ListSortDirection

[chintan]

Hi,

Recently we started using Q2 2009 controls so we have replaced the old binaries with the new one...

Now we have started getting an errors... "Ambiguous Reference for ListSortDirection"

The error is

Error    1    The type 'System.ComponentModel.ListSortDirection' exists in both 'c:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v3.0\system.dll' and 'd:\Chintan\CRM\10 - References\Assembly References\Referred\System.Windows.Controls.Data.dll'    C:\Documents and Settings\******\My Documents\Visual Studio 2008\Projects\SilverlightApplication1\SilverlightApplication1\MainPage.xaml.cs

If we remove the reference of System.Windows.Controls.Data.dll it asks to add the reference of this assembly and if we keep it then it shows ambiguous reference error.

Could you please help us to resolve this, actually we are trying to add the sortdescriptor following way and the error is on the line 12th

	public partial class MainPage : UserControl
	{
	public MainPage()
	{
	InitializeComponent();
	RadGridView gv = new RadGridView();
	gv.SortDescriptors.Add(new SortDescriptor()
	{
	Member = "FirstName",
	SortDirection = ListSortDirection.Ascending
	});
	}
	}

even i have uploaded the sample application on http://rapidshare.com/files/253138964/SilverlightApplication1.rar.html

the binary version is 2009.2.701.1020

Thanks,

Hello,

These binaries are for Silverlight 2. Silverlight 3 will be available officially on 10 July and we decided to postpone our Silverlight 3 release for Q2 SP1. In the meantime you can use our latest official Silverlight 3 compatible binaries.

Hello,
I have installed Silverlight 3 and upgraded to yesterday's SP (08122009), but am still having this ambiguous reference problem for ListSortDirection. Am I doing something wrong?
Thanks,
Drew

Hello Drew,

Most probably you have reference to the old System.Windows.Controls.Data - can you check this?

All the best,

Yes, thanks. I resolved this yesterday. That was the problem. I was thrown off because the old version is still distributed with the Telerik Dlls in the Service Pack.

Thanks again.

I'm getting the same error from the sample app.  Both the Silverlight system.dll and the Telerik dll are SL 3.0. See error message below.  I found that when i brought up the sample VS solution in VS2008 it needed to do a conversion.  I did a rebuild all, removed the VB examples, and ended up with the followiing errors.  How should I resolve them?

Thanks!

Hi Terry,

Please remove the reference to System.Windows.Controls.Data.dll to fix this.
