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.
