Constructors
DataSourceExpression() |
Initializes a new instance of the DataSourceExpression class. |
Properties
Context |
Gets the HttpContext instance of the owner control. |
DataSource |
Gets the data source object that is associated with the owner control. |
IsTrackingViewState |
Gets a value that indicates whether a data source expression object is tracking its view state changes. |
Owner |
Gets the owner control. |
ViewState |
Gets an instance of the StateBag class that contains the current view state information. |
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) |
Evaluates the DataSourceExpression instance using the IQueryable interface. |
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. |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
SaveViewState() |
Saves the current view state of the DataSourceExpression object. |
SetContext(Control, HttpContext, IQueryableDataSource) |
Sets the HTTP context of the DataSourceExpression object that uses the specified owner control, HttpContext instance, and IQueryableDataSource object. |
SetDirty() |
Marks the DataSourceExpression object so that its state will be saved in view state. |
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. |
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. |
IStateManager.LoadViewState(Object) |
When implemented by a class, loads the previously saved view state of the data source expression object. |
IStateManager.SaveViewState() |
When implemented by a class, saves the current view state of the DataSourceExpression object. |
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. |
