Best practice for binding user control data - how to do it?

Question

I have User Control with TextBoxes, Labels, .... Now I would like to get the same data binding functions as I would place controls directly on the form. I tried using an additional binding source and error provider in User Control, and I tried to make the properties of my controls available as a property.

Nothing succeeded. Therefore, there must be a solution to do this. So how?

Answer 1

I demonstrated a sample at https://github.com/edymtt/usercontrolwithdatabinding to illustrate some data binding scenarios that may apply to your question. In particular, I examined two scenarios:

• Implementation UserControlfor editing a basic property (string, integer, ...);
• An implementation UserControlfor editing properties of a complex type (for example, AddressPOCO);

Implementation UserControlfor editing the main property
