Following this instruction, I created an EF model (Database first) and DataSource.
I made BindingSource (bsUsers) for my form and bound DataGridView to it.
Here is how I import data when a form first launches:
_myDbContext = new MyDbContext(); _myDbContext.Users.Load(); bsUsers.DataSource = _myDbContext.Users.Local.ToBindingList();
Using DataGridView and other bound controls, I can add and modify records.
However, I was unable to determine how to filter the data. For instance, I'd like a textbox where I can enter a user name (or a portion of one) and have all other entries hidden.
It appears that filtering is not supported by the BindingList returned by the ToBidingList() method.
I did it.
bsUsers.Filter = "Id = 1";
bsUsers.Filter = "Username like 'admin'";

Alternatively, import your data into a
as well as the bsUsers. DataSource contains the list's filtered items, such as
users.Where( u=> u.Id == 1 ).ToList()
You may also use a list that implements IBindingListView in instead of your BindingList. Here are some possible arrows: Implementations of IBindingListView in general
