Remarks
Lookup editors store and display field values specified by the RepositoryItemLookUpEditBase.ValueMember and RepositoryItemLookUpEditBase.DisplayMember properties. You can obtain display values by corresponding key values via the RepositoryItemLookUpEdit.GetDisplayValueByKeyValue method call. However, the key field specified by the RepositoryItemLookUpEditBase.ValueMember property doesn’t necessarily contain unique values. In such a case, the RepositoryItemLookUpEdit.GetDisplayValueByKeyValue method returns a display value corresponding to the first occurrence of the specified key value.
The GetDisplayValueByMultipleKeyValues method allows you to assign additional search criteria if the key field is not unique. You must specify the array of fields and their values in addition to the key value. These arrays are set via the otherFields and otherValues parameters. If these parameters are not assigned, the GetDisplayValueByMultipleKeyValues method works like the RepositoryItemLookUpEdit.GetDisplayValueByKeyValue method.
Note that the otherFields and otherValues parameters must be arrays of the same length. Otherwise an exception is raised.
