There is a difference between the Silverlight and the WPF version of RadMap. The Silverlight version is based on the standard Silverlight MultiScaleImage control. Unfortunately, there is no such control in WPF, so we have created our own implementation of the MultiScaleImage. All panning and zooming features which are available in Silverlight's MultiScaleImage control are simulated in WPF using the available animation features. So, the Silverlight and the WPF version have a difference for panning and zooming using mouse when the spring animation feature is enabled (RadMap.UseSpringAnimations="True"). By default the feature is enabled. You can disable this feature to make the panning faster.
