| Name | Description | |
|---|---|---|
![]() | ParameterDataSourceExpression() | Initializes a new instance of the ParameterDataSourceExpression class. |
| 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.) |
![]() | Parameters | Gets the parameters that are associated with this DataSourceExpression object. |
![]() | 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 the default hash function. (Inherited from Object.) |
![]() | GetQueryable(IQueryable) | Evaluates the DataSourceExpression instance using the IQueryable interface. (Inherited from DataSourceExpression.) |
![]() | GetType() | |
![]() | LoadViewState(Object) | Loads the state of the values in the ParameterDataSourceExpression object that must be persisted.(Overrides DataSourceExpression.LoadViewState(Object).) |
![]() | MemberwiseClone() | |
![]() | SaveViewState() | Saves the current view state of the ParameterDataSourceExpression object.(Overrides DataSourceExpression.SaveViewState().) |
![]() | SetContext(Control, HttpContext, IQueryableDataSource) | Executes the expression by using the specified owner control, context, and data source.(Overrides DataSourceExpression.SetContext(Control, HttpContext, IQueryableDataSource).) |
![]() | 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 ParameterDataSourceExpression object so that the changes can be stored in the StateBag object for the object.(Overrides DataSourceExpression.TrackViewState().) |
| Name | Description | |
|---|---|---|
![]() ![]() | 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.) |
![]() ![]() | 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.) |
