Constructors
| OfTypeExpression() |
Initializes a new instance of the OfTypeExpression class. |
| OfTypeExpression(Type) |
Initializes a new instance of the OfTypeExpression class using a specified type. |
Properties
| 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) |
Methods
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetQueryable(IQueryable) |
Returns the query that the OfTypeExpression was performed on. |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| LoadViewState(Object) |
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(Control, HttpContext, IQueryableDataSource) |
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) |
Explicit Interface Implementations
| 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(Object) |
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) |
