Use the GroupIndex property to associate the Shell Combo Box editor with other DevExpress shell controls. Associated shell controls synchronize displayed content.
To associate supported shell controls, set their GroupIndex property to the same integer value. If the GroupIndex property is set to a negative value, the Shell Combo Box editor does not synchronize its content with other supported shell controls in an application.
You can use the GroupIndex property to synchronize content in the Shell Combo Box editor with the following shell controls:
TdxShellBreadcrumbEditA Shell Breadcrumb control.TdxShellListViewA Shell List View control.TdxShellTreeViewA Shell Tree View control.
The GroupIndex property’s default value is -1.
