DataObjectAttribute Class
Identifies a type as an object suitable for binding to an ObjectDataSource object. This class cannot be inherited.
Assembly: System (in System.dll)
The DataObjectAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | DataObjectAttribute() | Initializes a new instance of the DataObjectAttribute class. |
![]() ![]() | DataObjectAttribute(Boolean) | Initializes a new instance of the DataObjectAttribute class and indicates whether an object is suitable for binding to an ObjectDataSource object. |
| Name | Description | |
|---|---|---|
![]() ![]() | IsDataObject | Gets a value indicating whether an object should be considered suitable for binding to an ObjectDataSource object at design time. |
![]() | TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equals | Determines whether this instance of DataObjectAttribute fits the pattern of another object. (Overrides Attribute::Equals(Object).) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Returns the hash code for this instance. (Overrides Attribute::GetHashCode().) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsDefaultAttribute | Gets a value indicating whether the current value of the attribute is the default value for the attribute. (Overrides Attribute::IsDefaultAttribute().) |
![]() ![]() | Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() ![]() | DataObject | Indicates that the class is suitable for binding to an ObjectDataSource object at design time. This field is read-only. |
![]() ![]() ![]() | Default | Represents the default value of the DataObjectAttribute class, which indicates that the class is suitable for binding to an ObjectDataSource object at design time. This field is read-only. |
![]() ![]() ![]() | NonDataObject | Indicates that the class is not suitable for binding to an ObjectDataSource object at design time. This field is read-only. |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
![]() ![]() | _Attribute::Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
Use the DataObjectAttribute attribute to identify an object as suitable for use by an ObjectDataSource object. Design-time classes such as the ObjectDataSourceDesigner class use the DataObjectAttribute attribute to present suitable objects to bind to an ObjectDataSource object.

The following code example demonstrates how you can apply the DataObjectAttribute attribute to indicate an object is suitable for binding to an ObjectDataSource object. In this example, the NorthwindData object is intended for use with an ObjectDataSource object.
