As stated in the title: in RadPivotGrid, user should be able to drag and drop fields directly to row / aggregate / filter fields without having to check them first in the configuration panel. See attached image.

In current situation, user has to (a) first check the box to move the field to e.g. row fields and THEN to drag it to the order they want - this is TWO postbacks.
If this feature was implemented, users could drag the field from the config. panel and drop it directly in the place they want - only ONE postback.

Dragging and dropping is by far the most intuitive way of doing things in the pivot grid (what is "Move to row fields" supposed to mean to an average user???) so please consider this. It is a strikingly missing feature.
