Is there anyway to prevent the grid's multi-select selecting multiple rows while dragging?  I want multiselect, but only by using the control+click and shift+click methods.

I'm tasked with the burden of implementing a drag and drop from a WebGrid to a WebTree.  I don't have to drag and drop elements.  I only need to change the cursor, and calculate and change drop targets in the tree dynamically, if they drop into the tree, i need to fire a postback.  Though I got no clue how to implement this with Infragistics 8.1 (and I'm considering upgrading to 9.1 but fear it will turn into a giant can of worms) my first hurdle is preventing the grid from selecting rows while dragging.

Any help would be appreciated.
