Setting Null Value in an Optional Non-identifying Relationship Using ComboxBoxMay 06, 2009. The most common relationship in any data model is the one-to-many non-identifying relationship. Non-identifying relationship implies weak dependency relationship between parent and child entities. There are two kinds of non-identifying relationships, including optional and mandatory. The necessity of the parent entity is exactly one and zero or one in the mandatory and optional non-identifying relationship respectively. One problem I’ve tackled in many of my enterprise application is the presentation of complex data relationship such as optional non-identifying relationship using data binding techniques in Windows Forms applications. In this article, I will illustrate how to face this problem.
