Use the AllowMultipleSelectInControl property to specify the item selection mode in all of the groups in the control. If the property is set to false, then only a single item can be selected in the control no matter what is the SelectionMode property in the C1ToolBarItem set. For example, if the SelectionMode property is set to SelectionMode.MultiSelect and the AllowMultipleSelectInControl is set to false, then only a single item can be selected.
Note: AllowMultipleSelectInControl property has higher priority than SelectionMode property in C1ToolBarItem.
Use SelectionMode property to specify which mode of selection that the control should take.
