# 1683Setting a Filter On a Large Table While a Range Is Active Results in Slower Results Than Expected We have a large dataset (> 300.000 records). With Setrange(DateFrom,DateTo) we reduce the records to 40 - 50 records and show them in a devExpressGrid. Then we want to use a Filter to more restrict these records. Now the problem: we use an
optimized filter to filter the 40 - 50 records, but the filtering is very slow (ca. 10 sec.). Even when we have 10 records after the setrange and then filter these 10 records, the filtering also last's up to 10 sec.
CommentsThe internal filter bitmap was being evaluated before the range boundaries when navigating with a range and filter set.
