Hi
as Example i have an column
gridColumn_RoomsCount.MappingName = "RoomsCount";
gridColumn_RoomsCount.Name = "Rooms";
When ggc_QueryRecordMeetsFilterCriteria event raised in foreach (string filterName in filterLists.Keys) filtername = ColumnName so when i press ok on filter no matter what i choose the result will be 0 records . When i made MappingName the same as ColumnName everithing work fine : ). So the issue exists when Columnname!=Mapingname in that poitn when u filter u get 0 result/
