Does anyone know if it is possible and if yes, how, to remove
items from DataGrid by now knowing its index?
Suppose I have a class User and store its instances in an
Array which then is used as a source for the DataGrid. So far it's
good. But then I need to remove users from the DataGrid. At the
moment I just loop through the items and when I find a matching
remove it. But this is a bit slow with large data.
