How to use the MultiSelect mode in the LookUpEdit

We have implemented the MultiSelect mode in the LookUpEdit as an extension. To use it, you will need to add a reference to the DevExpress.Xpf.Grid.Extensions library and assign MultiSelectLookUpEditStyleSettings to the LookUpEdit StyleSettings property. If you wish to select records on a click basis (without the CTRL modifier), customize the editor's PopupContentTemplate and use the OneClickSelectionView as a GridControl view. Please note that the LookUpEdit does not support text editing in the MultiSelect mode.
