DataTrigger in a SelectionBoxTemplate?

[John]

I was able to bind a model's text and tooltip to the SelectionBoxTemplate. However, sometimes the tooltip is empty and sometimes it is populated.
However, without a datatrigger in place, even on the empty tooltips, I see an empty tooltip window popup which is a bit of annoyance. Any possible way to fix this?

Hello John,

Thank you for contacting us.

To avoid any misunderstanding, may I ask you to share how you have added the tooltip to the SelectionBoxTemplate. On which element the tooltip is shown? Is it possible to isolate this behavior in a standalone project so I can debug it on my side and provide you a suitable solution depending on your implementation?

I am looking forward to your reply.

Merry Christmas and Happy Holidays!

I did it very similar to this, except I set the tooltip

Hello John

Thank you for the additional information. 

To achieve your requirement you can use a trigger as you already suggested. I've attached a small example showing this approach. I hope it helps.
