The OfTypeExpression type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | OfTypeExpression() | Initializes a new instance of the OfTypeExpression class. |
![]() | OfTypeExpression(Type) | Initializes a new instance of the OfTypeExpression class using a specified type. |
| Name | Description | |
|---|---|---|
![]() | Context | Gets the HttpContext instance of the owner control. (Inherited from DataSourceExpression.) |
![]() | DataSource | Gets the data source object that is associated with the owner control. (Inherited from DataSourceExpression.) |
![]() | IsTrackingViewState | Gets a value that indicates whether a data source expression object is tracking its view state changes. (Inherited from DataSourceExpression.) |
![]() | Owner | Gets the owner control. (Inherited from DataSourceExpression.) |
![]() | TypeName | Gets or sets the type that the filter is based on. |
![]() | ViewState | Gets an instance of the StateBag class that contains the current view state information. (Inherited from DataSourceExpression.) |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from 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 | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetQueryable | Returns the query that the OfTypeExpression was performed on. (Overrides DataSourceExpression::GetQueryable(IQueryable).) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | LoadViewState | Loads the state of the values in the DataSourceExpression object that must be persisted. (Inherited from DataSourceExpression.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | SaveViewState | Saves the current view state of the DataSourceExpression object. (Inherited from DataSourceExpression.) |
![]() | SetContext | Sets the HTTP context of the DataSourceExpression object that uses the specified owner control, HttpContext instance, and IQueryableDataSource object. (Inherited from DataSourceExpression.) |
![]() | SetDirty | Marks the DataSourceExpression object so that its state will be saved in view state. (Inherited from DataSourceExpression.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | TrackViewState | Tracks view state changes of the DataSourceExpression object so that the changes can be stored in the StateBag object for the data source expression object. (Inherited from DataSourceExpression.) |
| Name | Description | |
|---|---|---|
![]() ![]() | IStateManager::IsTrackingViewState | When implemented by a class, gets a value that indicates whether a data source expression object is tracking its view state changes. (Inherited from DataSourceExpression.) |
![]() ![]() | IStateManager::LoadViewState | When implemented by a class, loads the previously saved view state of the data source expression object. (Inherited from DataSourceExpression.) |
![]() ![]() | IStateManager::SaveViewState | When implemented by a class, saves the current view state of the DataSourceExpression object. (Inherited from DataSourceExpression.) |
![]() ![]() | IStateManager::TrackViewState | When implemented by a class, tracks view state changes of the DataSourceExpression object so that the changes can be stored in the StateBag object for the data source expression object. (Inherited from DataSourceExpression.) |
