Specifies the design-time editor of the expression builder. This class cannot be inherited.


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

[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = false)]
public sealed class ExpressionEditorAttribute : Attribute

The ExpressionEditorAttribute type exposes the following members.

Public methodExpressionEditorAttribute(String)Initializes a new instance of the ExpressionEditorAttribute class using the specified type name.
Public methodExpressionEditorAttribute(Type)Initializes a new instance of the ExpressionEditorAttribute class using the specified type object.

Public propertyEditorTypeNameUsed by an expression editor to retrieve the editor type name.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Public methodEqualsIndicates whether this instance of the ExpressionEditorAttribute class and a specified object are equal. (Overrides Attribute.Equals(Object).)
Public methodGetHashCodeRetrieves the hash code for the value of this ExpressionEditorAttribute attribute. (Overrides Attribute.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

The ExpressionEditorAttribute class specifies the design-time expression editor for the expressions that are handled by an ExpressionBuilder class.

When editing a control property, you can set the property value to an expression by using an editor for the expression.

When developing an expression builder, you can mark the builder with the ExpressionEditorAttribute attribute to set the editor type value.
