Hi Vitor, 

 

Greetings from Syncfusion support. 

 

We were able to replicate the issue you reported. We would like to confirm whether you have set the value of the enableMultiTaskbar property to true, because, Virtual Scroll does not support multi taskbar feature in Gantt Chart. If yes, please remove the property form your application to avoid this issue. 

 

For more information on the limitations of Virtual Scroll, please refer our Online Documentation. 

 

Please contact us if the issue persists. 

 

Regards, 

Monisha.

Thanks Monisha!

I see this link about virtual scroll limitations but doesn't mention about multi taskbar feature limitation.

Anyway, thank you very much for the quick reply.

For the moment, I will disable the multi task feature.
