MultipleChoiceFilter - Filter Content not updated when item added to the collection

Mar 1 at 7:38 AM

I'm trying to implement a MultipleChoiceFilter in my application, I used an observable collection for the source of my datagrid and it works perfectly when my collection is fullfilled with the items before the display of the datagrid.

But when i add the data after, the sourcevalues is not updated and the filter list is empty. I tried to add a "notifyontargetupdated=on" on the source binding of my datagrid but nothing change, the list is still empty.

Sorry for my poor English ^^
