Use only one scroll bar for a grid with multiple master/detail levels.

A grid containing a number of groups (master), each with a number of lines (detail) is a representation of an order which is grouped for readability. When a group has a greater number of lines then fits on the screen, a scrollbar is added to the detail-view and when there are multiple groups the master-view also gets a scrollbar. When the user scrolls through the grid, only the master-view is scrolled (unless a row is selected, then only the detail-view is scrolled) and it feels like the program is behaving oddly, as half the rows are skipped.

To achieve this goal, we need the GridControl to have a height equal to the height of all content placed in a master-view. So, the scrollbar does not appear in either the master-view or in the detail-view. To allow scrolling, we need to put our GridControl into a XtraScrollableControl and set the GridControl.Dock property to DockStyle.Top.

We created the MyGridControl class - a descendant of the GridControl. MyGridControl works with MyGridView views and includes the CalcGridHeight() method, which is called when the appearance of the Master-View is changed.

To put MyGridControl in the XtraScrollableContainer, use the MyGridControl.InitScrolling method at runtime. Use the MyGridControl.InitScrollingInLayout method to initialize scrolling in a LayoutControlItem. 

Please note that if you want to change Bounds or Dock properties of MyGridControl at runtime, change similar properties of the MyGridControl.ScrollableContainer control.
