Too slow rendering

[Malgorzata Dobkowska]

Hello,

I have a problem with Gantt control. My Gantt chart has a lot of rows (over 200) and many custom/template columns. Unfortunately, a time needed to render the whole chart is about 6 seconds and this is too slow. Is there any way to improve the render time?

Hi Michal, 

 

We can load large data and improve the initial load performance by enabling the virtualization mode. Please find the below sample for your reference.

Regarding the custom templates you are using in Gantt columns, are you initialing any components in each column cells at the initial load. Can you please provide the templates you are using in Gantt columns, this information would be helpful for us to provide you a better solution. 

 

Regards, 

Bharath.
