I used the click Events and I yes, they block the selectedchange-Event
but that's the Problem. without the selectedChange-Event I do not know, on which row the user has klicked, so I can't start the interaction with the click row.
How do I get the Information, on which row the user has clicked? the click Event does not have any Parameters
You shouldn't handle the Click event. You can add custom views to the items and then handle their events. For example you can add panels and handle their click events.
