Exception in VS2013 designer with Rad Chart control

[Stephan]

Hi Telerik-Team,

quite often, when I click onto the XAML code for the RadCartesianChart the designer shows the following exception:

KeyNotFoundException: The given key was not present in the dictionary.
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
InnerException: None

I then need to close that page and reopen it to keep on working. Here is the code for my Chart:

<telerikChart:RadCartesianChart Grid.Row="1" x:Name="ProgressChart">
    <telerikChart:RadCartesianChart.VerticalAxis>
        <telerikChart:LinearAxis Maximum="100"/>
    </telerikChart:RadCartesianChart.VerticalAxis>
    <telerikChart:RadCartesianChart.HorizontalAxis>
        <telerikChart:CategoricalAxis/>
    </telerikChart:RadCartesianChart.HorizontalAxis>
    <telerikChart:AreaSeries Stroke="ForestGreen" StrokeThickness="1" Fill="LimeGreen">
        <telerikChart:AreaSeries.DataPoints>
            <charting:CategoricalDataPoint Value="40"/>
            <charting:CategoricalDataPoint Value="20"/>
            <charting:CategoricalDataPoint Value="40"/>
        </telerikChart:AreaSeries.DataPoints>
    </telerikChart:AreaSeries>
</telerikChart:RadCartesianChart>

I'm using this small piece of code in a rather new project. Lately I went from VS2012 to VS2013 with my much bigger project and I keep getting a lot of (different) exceptions in the designer. So practically all of the time I have to use Blend now to work on the XAML UI. Is there any way to collect some logs from the Telerik Controls in Visual Studio to check whether all of these issues are related to the controls? I've already been collecting VS logs and R# logs but without any errors in there.

Hi Deyan,

thanks for your update. I'm really looking forward to this fix.

Is the root cause for this issue also related to other designer error messages? For example,

ObjectDisposedException: Cannot access a disposed object.
Object name: 'NativeObject'.

at System.Windows.DependencyObject.MS.Internal.IManagedPeerBase.get_NativeObject()
at MS.Internal.XcpImports.DependencyObject_SetParentForInheritanceContextOnly(DependencyObject doh, DependencyObject parentDO)
at System.Windows.DependencyObject.UpdateEffectiveValue(DependencyProperty property, EffectiveValueEntry oldEntry, EffectiveValueEntry& newEntry, ValueOperation operation)
at System.Windows.DependencyObject.InvalidateProperty(DependencyProperty property)
at MS.Internal.FrameworkCallbacks.InvalidateProperty(IntPtr nativeTarget, UInt32 propertyId)

and more...

Stephan

Hi Stephan,

Thanks for writing back.

We are currently not aware of the issue with the disposed object. Is it easily reproducible on your side? Could you please describe how we can reproduce it so that we can make sure we address anything that might be wrong in our codebase?

Thanks for your time.

Hi Deyan,

Unfortunately, it's not easy to reproduce. It just happens in my bigger project. That's why I'd like to collect some logs from the Telerik controls when working with them in Visual Studio. This way I can check whether those other issues are related to your controls or not. In case they are I can show you some logs (I'm not talking about collecting logs in the WP8 app. I just want logs in Visual Studio).

For now, I will wait for your fixes. Maybe this resolves the other issues, too :)

Hi Deyan,

so there is no way to collect some RadControls logs in order to look out for some exceptions?

Stephan

Hello Stephan,

Thanks for writing back.

No, we do not collect any logs as of now.

Hi Deyan,

thanks for your reply. In the mean time I found a post at http://www.monkeyslaps.com/vs-issue-designer-failing/ that describes the same issue, also having the assumption that it has something todo with the Telerik Controls. I also started adding some controls to my newer/smaller app and now I get those messages regularly on those pages where I added some controls. I'll open a support ticket this evening and will attach my project. Hope this helps in hunting down this issue.

Stephan

Hi Deyan

I am still getting this exception. I am using your UI for Windows Phone 8 Q2 2014 controls. Can you please let me know if this is fixed?

Hi Manish,

Please, open a formal support ticket and send us your project, so that we can investigate the problem. Thank you.
