Hello Mike,

Have you enabled the RadChart.IntelligentLabelsEnabled property? If yes, we would suggest you to try to disable it (unfortunately currently there is no other workaround) as in scenarios when the control is populated with large amount of data, enabling the "intelligent labels" feature might cause noticeable performance degradation as it takes long time to execute the label positioning calculations.

If the problem persists, we would ask you to send us your control declaration so we can advise you properly how to proceed.

Hi Mike,

Thank you for elaborating on this.

We reviewed the attached source code and we would suggest you to try to reduce the Shadow.Blur values (currently set to 5 on multiple elements in your code) or remove the Shadow settings altogether in order to improve the rendering speed of your application.

Hope this helps.


All the best,
Freddie
