Unable to set initial size of dockbar


New to RhinoCommon(cs). I can’t seem to set the initial (onload) size of winforms dockbar. I have tried setting size of the dockbar like this:

private void CreateMyDockBar()
            var create_options = new DockBarCreateOptions
                DockLocation = DockBarDockLocation.Floating,
                Visible = false,
                DockStyle = DockBarDockStyle.LeftAndRight,
                FloatPoint = new System.Drawing.Point(760, 200) 

            dockbar = new ToolSearchRhinoDockBar();

            // this does now work
            dockbar.ResizeFloating(new System.Drawing.Size(400, 800));
