When I store the DATE value, I always store TIME too, so so like that 01/10/2015 15:30.
At my ejGrid, I'm just show de DATE, not TIME. You can see it at picture "1_filter.png". At my column, I set type as a DATE (not datetime) "4_column-definition.png"
Now, I'm trying to filter that column exacly with value 01/10/2015 using equals expression, but I think that ejGrid is trying compare with full date, not only date.
