Unable to cast object of type 'MS.Internal.ManagedObjectReference' to type 'Telerik.Windows.Controls.Animation

[Ramesh]

I use 2011 March version of Telerik Silverlight controls. I get the following exception some times when RadComboBox dropdown opens. There is nothing special about these RadComboBox in the XAML, see below for a sample.

 

 

 

<telerik:RadComboBox

 

 

 

DisplayMemberPath="Name"

 

 

 

SelectedValuePath="RefDataID"

 

 

 

SelectedValue="{Binding RefID, Mode=TwoWay, NotifyOnValidationError=true}"

 

 

 

ItemsSource="{Binding Source={StaticResource Reference}}" />

 

System.Windows.Markup.XamlParseException occurred

Hi Ramesh,

Thank you for contacting us.

We are not aware of such issue. Could you please try with the Latest Internal Build from yesterday. If the problem persists please send us your project, so that we can run it here locally and track down the source of the problem.

Looking forward to your reply.

Hello Chris,

With which version of the controls you are receiving this exception? Also, if you could send us the code that is raising this exception and some more details how to reproduce it. In that way we will be able to start researching the issue and provide a fix in a timely manner.

Thank you in advance.

Latest version: 2012.1.424.1050. Same exception here. But even in our project this bug happens in 1 case of 20+, so I think its very hard to reproduce this in another simple project.
Here some info I found, not sure if it somehow will help, but imho - this is better then nothing, maybe someone will find this useful.

Looks like removing this animation from RadComboBoxStyle fixes the bug, or at least I can't reproduce it at the moment:
<Setter Property="animation:AnimationManager.AnimationSelector">
      <Setter.Value>
        <animation:AnimationSelector>
          <animation:AnimationGroup AnimationName="Expand">
            <animation:SlideAnimation Direction="In" SlideMode="Top" TargetElementName="PopupRoot" />
          </animation:AnimationGroup>
          <animation:AnimationGroup AnimationName="Collapse">
            <animation:SlideAnimation Direction="Out" SlideMode="Top" TargetElementName="PopupRoot" />
          </animation:AnimationGroup>
        </animation:AnimationSelector>
      </Setter.Value>
    </Setter>

Hello Dumitru,

We are still not able to reproduce the issue. However, we will look into it further. Meanwhile, if you succeed in reproducing it in a sample project, open a support ticket and send it to us. In that way we will be able to track the problem in a timely manner.
I have logged the issue in PITS - you can track it here. Once we find a solution for the problem its status will be updated.

Thank You!
As I said, even in our project this bug doesn't happen always, only when app is running some time, and you actively use the combo box. So I don't think I can provide a sample solution that reproduces this.
Also i just got same exception with the same animation in RadExpander, so I think we will just remove all this kind of animation from all styles.
