DataBinding Class

Contains information about a single data-binding expression in an ASP.NET server control, which allows rapid-application development (RAD) designers, such as Microsoft Visual Studio, to create data-binding expressions at design time. This class cannot be inherited.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

Each data-binding expression in a server control is represented at design time by an instance of the DataBinding class. Any server control that contains one or more data-binding expressions has a DataBindingCollection object that contains the DataBinding objects. This collection is accessible through the Control class implementing the IDataBindingsAccessor interface. When you create a custom RAD designer, use that implementation to access the collection. Any DataBinding or DataBindingCollection objects associated with a server control exist only at design time. They do not exist at run time and, therefore, are not accessible during run time.

The following code example creates a DataBinding object and sets it equal to an existing object in the control's DataBindingCollection collection that has a propertyName parameter with a value of Text. If the collection contains a DataBinding object with a propertyName value of Text, this code returns the value of the object's Expression property. If there is no such object, it returns an empty string ("").

No code example is currently available or this language may not be supported.
