You can reset the binding here, and also check what might have stolen it by checking what’s currently bound to those keys.

You can also use the DataSet’s AcceptChanges() method to apply the deletes fully. ds.Tables[0].Rows[0].Delete(); ds.AcceptChanges();
Dictionary<TKey, TValue> uses an IEqualityComparer<TKey> for comparing the keys. If you do not explicitly specify the comparer when you construct the dictionary, it will use EqualityComparer<TKey>.Default. Since neither MyClass nor MyStruct implement IEquatable<T>, the default equality comparer will call Object.Equals and Object.GetHashCode for comparing instances.

AddRoles must come before AddEntityFrameworkStores
What type are you interested in? The return type of the method/property/event etc? If so, I don’t think there’s anything in MemberInfo to let you get at it directly – you’ll need to cast and use MethodInfo.ReturnType, PropertyInfo.PropertyType, FieldInfo.FieldType, EventInfo.EventHandlerType and any others I’ve forgotten. (Remember that types themselves can be members. Not sure what …
What worked for me was adding panel1_MouseEnter EventHandler: private void panel1_MouseEnter(object sender, EventArgs e) { panel1.Focus(); }
