Hi,
I'm having some issues using the Gauges: it seems that every element added to the Indicators or CustomItems generates a System.Windows.Data Error. The example in this code
<telerik:RadHorizontalLinearGauge x:Name="EntireGauge" Grid.Row="1">
<telerik:LinearScale Min="0" Max="10" ShowFirstLabel="False" MajorTicks="0" Fill="Green">
<telerik:LinearScale.Indicators>
<telerik:Marker x:Name="PreMarker" Value="3" />
</telerik:LinearScale.Indicators>
<telerik:LinearScale.CustomItems>
<TextBlock Text="CustomItemText" telerik:ScaleObject.Value="5" />
</telerik:LinearScale.CustomItems>
</telerik:LinearScale>
</telerik:RadHorizontalLinearGauge>

cause the following errors:

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='IndicatorGroup'

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TextBlock'


I'm using the version 2012.1.416.40: could you explain me how to fix the issue?

Thank you so much.

Best Regards,
Rocco

Hello Rocco,

We are aware of this problem. It occurs because of the nature of the ItemsControl. This error is handled by ItemsControl internally so you can just ignore this message.
We are looking for the way to eliminate this message. You can check when this problem will be fixed using the following PITS:

Wow almost 2 years later and there's no fix?  Makes it hard to watch for binding errors in my code when I keep getting Telerik errors in my output window.

Hi David,

This problem in the RadGauge control has been fixed a long time ago (November 9, 2012). We can't reproduce it using our latest binaries and VS2012. Could you, please, provide us with a small sample solution which reproduces it?

Hi Chris,

I don't think I understand how your reply is related to the current thread. If you have a question about the RibbonView can you please open new forum and ask it there. This will help us to organize better our communication history and assist our users better.
