Hello Michel,

I have been investigating into this behavior, and I can confirm that the XamPivotDataSelector will normally scroll when using it – this particular sample project in the Infragistics WPF Samples Browser is currently showing how you can modify the template of the controls within the data selector and essentially make it look different.

In the sample, the XamDataTree is re-templated, and for some reason when this sample was built, the ScrollBars were taken out of the default template for the XamDataTree. I am unsure why this was done, but for this particular sample, it appears to have been intentional. If you want to change this, you can do the following:

I am unsure if you are running the Samples Browser from its source code or if you are running an isolated version of this sample, but you will need to replace the re-templated XamDataTree with the default-template one. This default template can be found in the generic.xaml file commonly found at the following directory when Infragistics controls are installed:

C:\Program Files (x86)\Infragistics\<version>\WPF\DefaultStyles\DataTree\generic.xaml

If you take the default template for XamDataTree and replace it in the sample, you should be able to scroll the tree in the data selector.

Please let me know if you have any other questions or concerns on this matter.
