The type 'DataAxisTicksItemsControl' was not found

[Gilmar]

I am using the object RadMap with version 2012.3.1129.1050 library Telerik.Windows.Controls.DataVisualization but the boot screen that has this component gives the following error

The type 'DataAxisTicksItemsControl' was not found

After this error upgraded version 2013.1 220 but the error persists.

What might be happening?

Below is my code in xaml
