These examples illustrate how to enable the Multi Selection feature in the VGridControl. Simply place the SelectionProvider component onto a form. Since this component implements the IExtenderProvider interface, the MultiSelect property will be shown for the VGridControl in the Visual Studio Property Grid. So, you will be able to turn this option on at design time. At runtime, use the SelectionProvider.SetMultiSelect method.
In short, selection operates in a similar manner as in the GridControl. By holding SHIFT, you can select cell ranges while by holding CTRL, you can select individual cells. In addition, category rows can be selected as well.
In the case of a MultiEditorRow, separate cells within this row can be selected by holding CTRL. If you hold SHIFT, a whole MultiEditorRow will be selected.
