Hello David Klitzke.
I am aware of XtraPivotGrid but what I am looking for is 'Editable' PivotGrid similar to the one you can find in the below URL
There is a workaround to use XtraPivotGrid as an editable control but it is a complex procedure and I do not know how to link DevForce with it.
I think DynamicProperties or DynamicEntities can be used to achieve the Matrix Input.
I appreciate your help.
