Devexpress slow auto filter in gridlookupedit

Symptom: Your auto filter is very slow with multi second delay between keystrokes in gridlookupedit when filtering on the column also set to Display Member. Especially with large amount of data rows eg > 12000

Solution: Change the Display Member property to same column as Value Member. Then implement CustomDisplayText to customize the display.

PS. This is on devexpress 11.2 so don’t know if this is maybe fixed in newer versions.
