It's InfragisticsSL4.v10.3

Version: 10.3.20103.1006

No Service Release applied, but not sure where to check it.

Hi,

That also seems ok to me, last think that comes to my mind is if eventually your project is configured to build with Silverlight 3.

Could you send us a sample project which we could use for reproducing the issue and debuging?

Thanks,

I have the "InfragisticsSL4.Controls.Menus.XamMenu.v10.3" referenced on my project actually.

And my full xmlns definition follow:

<UserControl x:Class="Namespace.Namespace.DispatchView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
    mc:Ignorable="d" xmlns:ddm="clr-namespace:Infragistics.DragDrop;assembly=InfragisticsSL4.DragDrop.v10.3"
    d:DesignHeight="418" d:DesignWidth="1405"
    xmlns:ig="http://schemas.infragistics.com/xaml"
    xmlns:igPrim="http://schemas.infragistics.com/xaml/primitives"
    xmlns:layoutToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Layout.Toolkit">

HI, I got a similiar error message because I was missing a Reference.

 Make sure you have the Infragistics.controls.Menu.XamMenu Reference.

Hi,

I am not able to reproduce the issue in the versio you are using either. I am guessing it is something related to the rest of your code, could you copy paste your xmlns definitions?

If you are able to provide a sample project where I can reproduce the issue it would be best (and attach it to the current thread from the Options tab).

Thanks,
