Hello Bruce,

Thank you for contacting us.

You can use the SelectedItems collection to programmatically select items. I have attached a sample that demonstrates this. Unfortunately, this will work on iOS only because we have an issue on Android where the selection is not properly updated when we modify the SelectedItems collection. I have raised the priority of the issue and the fix should be available in the next internal build.

You mentioned that the ItemTapped event does not always work on iOS, but I couldn't reproduce this issue. It could be something that is specific to your setup, could you please send us an example?

I look forward to your reply.

I attempted to do something similar, but as you said, it does not work on Android and hence, is not an acceptable solution.  I'll continue to look for a fix.

I'll also see if I can create a separate project duplicating the iOS ItemTapped issue.

Hello Bruce,

With the R2 SP 2017 release which is available as of yesterday, we have included a fix for the issue you are observing in Android. However, there is another undesired behavior we have diagnosed which can be replicated on devices that use 6.0 or later Android version(sometimes the items do not appear as selected although they actually are). We should have a fix for that with the next minor build(next Friday). With this in mind, I suggest you test the approach my colleague has suggested for devices that use a lower version of Android and wait until next Friday to test the higher versions.

Have a great rest of the week.
