Hi All
I have 2 DataGrid named dg1 & dg2 that binds to List1 & List2
List1 has 4 items and List2 has no items
in a Button_Click I Remove 2 items from List1 and Add 2 Items to List2
at the end of Button_Click I refresh dg1 and dg2 but nothing changed in DataGrids
dg1.ItemsSource = List1;
dg2.ItemsSource = List2;
what's wrong?
