In our PivotGrid control, we have provided support to filter values from column and rows using text filters with the help of filter popups available in grouping bar header areas. Also, we have provided the support to perform advanced filtering and sorting using same filter popup as same as in MS Excel. With the help our advanced filtering support, user can apply label and value filters for our control. When we are trying to filter the values using either text filters or advanced filters, it takes little bit more time to complete the action compared to filtering feature in MS Excel. Hence, we need to improve our filtering performance which is closer to the filtering performance of MS Excel.
