One of your Diagram samples contains a nice RadDiagramToolbox that I would like to use. However, the "Code" section merely contains a stripped Example.xaml...?
How can I make the RadDiagramToolbox look like in the attached image?
I don't think anything is stripped, all the code of the samples is at your disposal inside the QSF (quick start framework, ...\Telerik\RadControls for WPF Q3 2012\Demos\Examples\Diagrams\).
If you need the shapes-toolbox you have to reference the Extensions (Telerik.Windows.Controls.Diagrams.Extensions.dll). Note that these extensions also depend on the Input (Telerik.Windows.Controls.Input.dll) and Navigation (Telerik.Windows.Controls.Navigation.dll) assemblies.
