Foreign key value can't deleted Directly in mvc

Say for example, the "country id" of Country table is referred in "State" table. In that case, if you try to delete the Country table's record, you can't. Since it is referred in "State" table. So first, you need to delete the "Child" table's record, then try to delete the "Parent" table's record. Meant that, first delete the record in "State" table then go with "Country" table.

 

Hope this helps!

You can't ..first parent should get deleted.

 

And idely it should not allowed in any scanario. 

 

Everytime you will get key voilation error.
