DataBinding Class

.NET Framework (current version)

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)

Syntax

C++

public ref class DataBinding sealed

Constructors

	Name	Description
	DataBinding(String^, Type^, String^)	Initializes a new instance of the DataBinding class.

Properties

	Name	Description
	Expression	Gets or sets the data-binding expression to be evaluated.
	PropertyName	Gets the name of the ASP.NET server control property to bind data to.
	PropertyType	Gets the .NET Framework type of the data-bound ASP.NET server control property.

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is the same instance of the DataBinding class as the current object.(Overrides Object::Equals(Object^).)
	GetHashCode()	Retrieves the hash code for an instance of the DataBinding object.(Overrides Object::GetHashCode().)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Remarks

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.

Examples

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 ("").
