ChartHierarchicalViewDescriptor not found

[Eric]

I am trying to build a hiearchical chart and have the following code:

<Telerik:RadChart Height="350" x:Name="WeightChart" Width="750">
    <Telerik:RadChart.HierarchicalViewDescriptors>
        <Telerik:ChartHierarchicalViewDescriptor>

        </Telerik:ChartHierarchicalViewDescriptor>
    </Telerik:RadChart.HierarchicalViewDescriptors>
</Telerik:RadChart>

And I get the following error message: 

The tag 'ChartHierarchicalViewDescriptor' does not exist in XML namespace 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting'

I looked in your documentation and it is included in that namespace.

I found the solution. If you drag and drop a control onto a page, it adds the following xmlns reference:

xmlns:Telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting"

You should really have this one:

xmlns:Telerik="http://schemas.telerik.com/2008/xaml/presentation"

Should this be reported as an issue to be fixed? It's annoying.

Hi Eric,

Actually ChartHierarchicalViewDescriptor is in the Telerik.Windows.Controls.Charting namespace and not in Telerik.Windows.Controls namespace and that is why you received the error when using clr-namespace directive.

You either need to use the schema directive xmlns:Telerik="http://schemas.telerik.com/2008/xaml/presentation" that wraps both Telerik.Windows.Controls and Telerik.Windows.Controls.Charting namespaces (recommended), or you need to add separate clr-namespace directives for each namespace.
