@duke7553 do you think this may be a similar issue to the one you fixed for templated columns in #4206?

FYI @RBrid

[lukeblevins]

@michael-hawker It does indeed seem similar. I wonder if my solution from before can be adapted to DataGridCheckboxColumn

[michael-hawker]

@duke7553 that's what I was wondering as well. Not sure if we have clear repro steps yet, though probably doesn't hurt to add a checkbox column to our sample and see if we can see the same issue. Is this something you're up for helping us investigate and take a look at or only once we have explicit repro steps? Thanks!

[lukeblevins]

No guarantees given my schedule, but I can probably take a look at it during the coming weeks and see if I can reproduce and fix it similar to the other bug.

Steps from the reporter would be 👌 too.

when I point to the checkbox the checkbox is not activated
