User Story 13: As a user I would like to filter & select primary data and download only the selected

[DavidBlaa]

The System should have a filter for subsampling primary data in order to download these subsamples.

• Reactivate the Filter/Sorting functions in the Grid
• The Dataset Manager should be able to handle filtered/sorted query
• Create Unit tests for Filter/Sorting functions in the Grid
• Add a function to return the number of rows matching a filter expression.
• Check all available filter options in the UI
• Number of rows in the grid missmatches with the filtered result number
• Downloaded primary data, filtered or not, includes one extra empty row at the end.

After filtering, the entire line number is not updated. Filtered out data is displayed as an empty line.
Filtered data has extra information (id, orderno, timestamp, versionid) they are added to the downloaded excel file only in data side, but not in the header.

Hi @javadch
this is for you :D

The Datasetmanager has a function to load datatuples from the database and convert it to a datatable.
In addition, the filter options now come back.
To display the data in a table, the system needs a function that counts the rows from the filtered result.

@DavidBlaa, I added a function RowCount to the DatasetManager class. It has two overloads, one accepts a FilterExpression.

@DavidBlaa One extra empty row is added to the download file.
Other functionalities are working properly as expected.
