It is possible but I would have to play with this a little bit. They have the ability to embed a control...I also know that these can be extended which would require you to create a new embedable control by inheriting the wrapped combo which would then support the grid. I cannot tell you how to do this since I have not done this before, but I do know it is possible.This might be a question better suited for the DevExpress forum. You would want to ask how to create custom embeddable grid controls.
