RadGridVIew with 50 columns and 40 rows performance

[B]

Hi,

When I create a simple RadGridView (*) with 50 columns and 40 rows that are visible on the screen at the same time this becomes slow. Both the initial filling of the grid and scrolling through them is slow.

Is there some option I missed?

When I profile it almost all of the time is spent in Windows dll's:

Functions Doing Most Individual Work
Name Exclusive Samples %
[PresentationCore.ni.dll] 75,78

Functions Doing Most Individual Work
Name Exclusive Samples %
[PresentationFramework.ni.dll] 10,20


The system I ran the performance test on: Intel Core i7-3632QM 2.2Ghz, 8G memory.

(*)only text columns, no converters, no sorting, no filtering

Regards,

Bayram

Hello Bayram,

RadGridView is a virtualized control and its elements are reused as they go in and out the view area. This increases the loading performance, however, the more the visual elements into view are, the slower the loading will be. You can check our online documentation explaining how the UI virtualization works. Looking at your definition, you have configured the GridView fine.

Generally, in order to improve the performance, I can suggest you going through our online documentation on possible reasons why there would be degraded performance with it.

I can also suggest you consider using Lightweight Templates for improving such performance problems.

Another optimization would be to disable the Touch Support. You can refer to the bottom of the Touch Support article. Basically you should set it to false in code behind:
TouchManager.IsTouchEnabled = false;

With Q2 2014 SP release of UI for WPF we added the option to turn off the generating of the automation peers through the new global AutomationMode property of the AutomationManager. You can check the UI Automation Support article on how to set the AutomationMode property to Disabled.

I hope those tips help.

Regards,
Didie
