Sorry but I forgot to mention the part about i want to hide the column header using LabelLocation="Hidden" in the field layout settings.  Basically when I hide the column headers, the cellsinviewchange doesn't trigger for object type data item.

Hello Chinh,

I have modified the sample, so now it has objects and the tooltip seems to work on my side. If the sample doesn’t satisfies your needs, feel free to modify it, so it reproduces your behavior and send it back to us, so we could be able to investigate it further for you.

Looking forward for your reply.

Hi Stefan, the example you provided doesn't work for the case when I change the underlying type of the datatable item from typeof(int) to typeof(object).  Can you please advise?

Thanks,

Chinh

Hello,

Thank you for your feedback. I am glad that you resolved your issue and I believe that other community members may benefit from this as well.

Thanks again.

Solved.  Here is the solution that I used:

ToolTipService.SetIsEnabled(cvp, true);
