Is it possible to configure the grid to use server filtering with multiple values (ie checkboxes) and have many columns in the filter. e.g.
(ColA = A) and (ColB = B or ColB = BB) and (ColC = C or ColC = CC)
After enabling server filtering on the grid we are using and setting the columns filterable property to include a datasource to read its values from the server, it looks like each column resets any other columns filter, only allowing a single column to contribute to the filter logic.
I notice that the demos for multi checkbox filtering seem to be able to do this, but they are using odata as the data source type for the overall grid.
