Which component to choose to work with EF model classes?

Question

MySQL

Hello!
Now I am developing a simple application that should work with the database. The main functionality (CRUD operations) is already ready. Now I want to find a convenient way to output data from the database to the program interface. Tried to use DataGrid and on an example of one table selected DbSet<> of the corresponding class as a source. The advantage of this component is that it allows you to easily change data, add and delete them. But the question is this: for example, there is a one-to-many relationship between two tables T1 and T2 with the corresponding foreign key T2_id, and when adding a new row to the table, you have to manually enter T2_id. So, I would like to know if it is possible somehow to "shove" a ComboBox in the T2_id cells, in which one could choose one option from those available in the T2 table.
Thoughts are now confused and I explained as best I could at the moment) If some points are not clear, I will later try to describe the situation with pictures, as I see it.

Answer 1

Basically DataGrid can have any other controls in cells, including ComboBox.
You only need to bind not the entire DataSet, but manually specify which columns to take from it (AutoGenerateColumns="False") and take DataGridComboBoxColumn or DataGridTemplateColumn for the ID column.

Answer 2

telerik has no such components. devexpress is not recommended.
I do not advertise this, but everything is quite easy to set up there)

Answer 3

Do you have dependencies in your model?
those in T1 must have a property public ICollection T2{get; set;}
and in T2 should be public T1 T1 {get; set;}
the main thing is to set up the bindings and get the data context.T1Set.Include("T2")
