Remarks
The GridSplitContainer supports the Split Presentation feature for a GridControl. This feature allows an end-user to split a GridControl horizontally or vertically.
Horizontal Split:
Vertical Split:
When added from a toolbox, a GridSplitContainer will contain a new GridControl internally. This technique for creating a GridSplitContainer is applicable for new projects.
Another way of creating a GridSplitContainer is appropriate for GridControls that exist in your old applications. At design time, click the Grid Control’s tag and then click the Add split container link in the Grid Control Tasks pane:
The Add split container link will create a new GridSplitContainer and place your old GridControl into the newly created container.
A GridSplitContainer doesn’t split the internal Grid Control at design time. The split functionality needs to be activated at runtime by an end-user or via the GridSplitContainer.ShowSplitView method.
If the GridSplitContainer.SynchronizeScrolling property is set to Default or True, certain grid properties are automatically adjusted when the grid control is split. When it is split vertically, the column headers are automatically made visible and horizontal scrolling is disabled. If you do not need this behavior, you can restore the previous settings via the GridOptionsView.ShowColumnHeaders and GridView.HorzScrollVisibility options after the grid is split. When the grid is split horizontally, the vertical scrolling is disabled via the GridView.VertScrollVisibility option. If required, you can enable vertical scrolling using this property after the grid is split.
