How to make multi selectable (datatemplate) if property is get only? Maybe must to use template.
Look attached image.
OK. I may use this, but if in template content put additional element and shift+select will not work when click into custome template element.
// this is example only for UI (shift+mouse click)
"3 2 2 0"
Can I use multiselection at runtime + logic from UI (shift+mouse click) and how?
