A filter is a set of conditions that can be used to limit the data that will appear in a FastReport. For example, lets say you are viewing the Summary by Source and Material report and you only want to view Tickets for specific Materials. This can be accomplished this using a Filter.
You can create filter conditions using Filter Dropdown lists or the Filter builder.
Example

Here is the same report, for the same report period with a filter that excludes Materials that are not a type of asphalt product:
Sorting
The Filter grid control does not allow you to change the sort order of the data within the grid. Clicking on the column headers will not change the sort order of the data.
Each FastReport relies on its data to be sorted in a specific order. Allowing you to sort the report data in the Filter grid would give you the incorrect impression that the order of the data in the FastReport should change too.
