Setting Null Value in an Optional Non-identifying Relationship Using ComboxBox
May 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.
Setting Null Value to an Entity Property Through Textbox Control
May 12, 2009.

When you develop a rich client application using the Windows forms, data binding techniques and a Textbox to enter the simple data, and you want to set null the optional attributes of the underlying data source by leaving in blank the Text property of the Textbox control; then there is a missing feature for the Formatting and Advanced Binding dialog box for null values. They should have a checkbox there to allow people to use blank as null. In this article, I will show one simple solution to this bug.
