  • Setting Null Value to an Entity Property Through Textbox Control5/15/2012 4:33:58 PM. In this article, I want to document a bug in Visual Studio. NET concerning to setting a null value to entity property’s through a Textbox control. There is a common scenario to have an entity type in your data model where some attributes are optional. 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.
