It should be possible to persist the current configuration of RadPivotGrid so that when the settings are loaded, the settings of the RadPivotGrid should appear as when they were saved. This includes the column/row/filter/aggregate descriptors, the width/height of the resized rows/columns and the applied filters.
Implement "Calculated Fields" support in RadPivotGrid
FIX. RadPivotGrid - MouseUp is not fired for data cells
To reproduce show a message box in the MouseDown event of the control and move the mouse over the data cells
