Slow RadChart in DockPanel

[Filipe Rodrigues]

Hi,

My application becomes very slow when I generate radcharts inside dockpanels...

Here is the code:

Dim dp As New DockPanel
dp.Text = "Panel"
dp.CloseButtonVisible = False
dp.DropDownButtonVisible = False
Dim chart As New RadChart
chart.Dock = DockStyle.Fill
dp.Controls.Add(chart)
DockingManager1.SetDock(dp, DockPosition.Fill)

What I'm doing wrong?

Hello Filipe Rodrigues,

Unfortunately you are not doing anything wrong. We are aware of some performance issues with our new charting engine and are currently working on them as we speak. Resize operations require re-rendering of the image which is currently a costly operation. We would advise to reduce resizing as much as possible until we are able to improve runtime performance.

We apologize for the inconvenience.

Best wishes,

Hi,
The problem doesn't occurs only when the chart is resized! I put the chart with dock = none and the problem remains. I think the problem is when I put it in a dockpanel.
How can I work around this?
Thanks.

Hello Filipe Rodrigues,
We tested locally and were unable to verify the "slow" behavior that you have reported. Docking manager operates correctly. If there is a performance penalty it is caused explicitly by the charting control. The charting engine is being optimized at the moment so we believe performance will increase dramatically very soon (in one of the upcoming SPs maybe).

Hi,
I need to increase the radchart performance to show our prototype to a costumer!
While the SP isn't ready, is there any work arround to the problem? Like clearing chart series, or chart resizing while resizing the dockpanel?
Any help?
Thanks

Hi Filipe Rodrigues,

We have already made some performance optimizations to our windows forms chart. If you submit a support ticket we can give you a unofficial build with the optimizations so you can do your demo.

What is the status of this problem.

I am having the same issue.  I add many small charts even with no data series set to a flowpanel that is in a dock panel, and then dragging the panel is unusably slow.

I just wanted to mention that the very first post in this series is a very good and concise "How-to" of how to use the dock panel and any subsequent controls programatically.

Thanks!
