We have included the WPF XamPivotGrid control in a custom usercontrol and incorporated this in our application. The problem is that the overall performance, especially when expanding dimensions is pretty bad. When expanding a dimension with about 200 members the whole control freezes for about one and a half minute which is of course not acceptable for our customers.

We are using a SSAS cube as a datasource and connect to that using the ADOMD datasource method. We do not use any styling, additional XAML/code behind properties so it is pretty much a very basic setup. We are using the 2011 controls.

Is there anything I can do to improve the performance?
