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

NameDescription
System_CAPS_pubmethodExpressionEditorAttribute(String)

Initializes a new instance of the ExpressionEditorAttribute class using the specified type name.

System_CAPS_pubmethodExpressionEditorAttribute(Type)

Initializes a new instance of the ExpressionEditorAttribute class using the specified type object.

NameDescription
System_CAPS_pubpropertyEditorTypeName

Used by an expression editor to retrieve the editor type name.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Indicates whether this instance of the ExpressionEditorAttribute class and a specified object are equal.(Overrides Attribute.Equals(Object).)

System_CAPS_pubmethodGetHashCode()

Retrieves the hash code for the value of this ExpressionEditorAttribute attribute.(Overrides Attribute.GetHashCode().)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides 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.
