WPF Pivot Grid Speed Improvements

14 July 2010

Check out these performance improvements for the DevExpress WPF Pivot Grid, DXPivotGrid:

  • Field values now expand and collapse twice as fast.
  • Improved scrolling speed in the Summary Type Display mode. The scrolling using the left/right arrow keys is now much faster.

How fast?

Here’s a project that uses our WPF Pivot Grid in a data intensive scenario:

DevExpress WPF Pivot Grid

To measure the difference, we took a couple of traces of the operations. For the trace, I've collapsed and expanded the first row area group in the WPF Pivot Grid project (screenshot above).

Here’s the results: 17,711 ms before and 7,106 ms after - expanding is two times faster!

Trace - Before Trace - After

Coming Soon

Unfortunately, these improvements are not in the latest release of DXperience v2010.1.5 yet. They will be in a future release so stay tuned.

Drop me a line below with your thoughts.

I noticed the Excel export is missing in WPF, that would be kind of nice to have again.

Thanks. The regular DXGrid can print/export just fine. The DXPivotGrid will get this feature in the future. Track this suggestion to get updates on it's progress:

Yeah, sorry, I just meant the pivot grid. I have started tracking that suggestion.

How many records are in your test data set?

Not so big. Our main problem on WPF-platform is drawing performance. This is the case we were able to overcome WPF limitations. To demonstrate an issue better, we have configured the PivotGrid to show many small cells.
