Despite controlling when a FillScenegraph occur - by enabling and disabling the event, the chart gets re-drawn whenever I move the mouse across the window. I can see that the FillScenegraph event control works as expected and the breakpoints inside my event handler does not get hitexcept when the fillscenegraph event is enabled.
What other events can cause re-drawing of the window? Is there a property that I forgot to set. How can I make sure that the window is re-drawn only when required.
Thanks

Displaying the context menu for the Chart is cauaing the FillSecenGraph event to be triggered. My graph has alot of data points and it appears that performance to display the contexct menu is being affected. It is taking about fours seconds just to display the context menu with 4 items. I would not have expected the context menu to trigger the Fill Scene Graph event.
I have tried turning off the Tooltips on the chart in the chart's MouseDown event and this semes to have helped a little. I am using 2012.1 with the first Service Pack and .NetFramework Version 4 of the controls in Vb under VS 2010
Thank you
I took the latest service release and changed
Chart.Tooltips.Display =
TooltipDisplay.Never;
and the control doesnt refrsh on loosing focus - moving mouse out of the window area.
Ok, downloaded the service release. Shall check and post my response at the earliest.
Will it work wih 2010 vol 2?
Thanks.
We fixed one issue that the chart is repainting when the mouse goes out of the chart (you need to disable the tooltips for this). Can you try applying the latest service release and see if it is better?
