The simple answer is this is not possible. When you set an anchor, the dock style clears. And vise versa if you set the dock style. Under the covers, we use the same bit fields to represent dock and anchor, so it is not possible to get into a conflicting state.

These scenarios are in a form which employs a dock and anchor layout engine.

Keeping a fixed distance from an edge – If you have a control you want to remain a fixed distance from an edge of the parent.

Anchor Bottom|Right

Resizing a child control when the parent grows/shrinks – If you have a control you want to resize when the parent resizes using opposite anchors (Left | Right) or (Top | Bottom) will help maintain the same distance from the edge as the parent resizes.

Anchor = Top|Bottom Anchor = Left|Right

These scenarios are in a form which employs a dock and anchor layout engine.

Always glued to one edge of the form - Dock Layout can generally be represented by combinations of Anchors, but it's quite handy for things that always need to be glued to one edge of the parent control.

Splitter layouts – through a combination of Dock styles, splitter style layouts can be achieved. This scenario is not as important in Whidbey, as we have provided a SplitContainer to do this layout magic for you.
