[Solved] Memory leaks

[Andrew]

Hello,

I found 2 memory leaks (with grouping and scrolling).

Open      http://demos.telerik.com/silverlight/#GridView/Performance

After opening this page memory usage is 169MB. After grouping by Name column memory usage increase to 173MB. And after removing grouping it increase to 193MB.

Now click the first row and scroll down with an arrow key (not mouse). After 500 rows memory usage increase by 240MB.

I have service pack now, but problem with grouping remains. Open  http://demos.telerik.com/silverlight/#GridView/Performance  again.

At start: 155MB

Group by Name: 161MB

Open 'Boston Crab Meat' group: 170MB

After scrolling (using mouse or keyboard) few hundreds rows: 174MB

Delete grouping: 223MB

After some time: 207MB

 

So 50MB was lost.

Hello Andrew,

Please, excuse us for the late reply.

It is expected to have memory consumption while scrolling, grouping or remove grouping actions are performed for a grid with 1 mln. records as the example demonstrates. But we believe most of the memory leaks was addressed in our SP1. You can refer to this video that shows significant improvements in memory usage. 

Thank you for your valuable feedback.
 
Best wishes,
