The easiest way to search by multiple columns in LookUpEdit is to use the SearchLookUpEditStyleSettings class as demonstrated in the How to: Create a SearchLookUpEdit and Bind it to Data article.
If you would like to filter by multiple columns when a user types directly in the edit box instead, create a LookUpEditStrategy descendant and override the UpdateDisplayFilter method where the filter criteria is set.

Hi, I have downloaded the example for 14.2.3 and it fails to run as it throws an exception:
Unable to cast object of type 'EditorsDataProxy2' to type 'EditorsDataProxy1'.
However, if I run it using earlier versions it runs with no problem.
Can you let me know a workaround, as I have just upgraded our project from 14.1.4 to 14.2.3 and this use case is blocking me.
Regards,
JK
