Constructors

ParameterDataSourceExpression()

Initializes a new instance of the ParameterDataSourceExpression class.

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)
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)

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. (Inherited from DataSourceExpression)
GetType()	Gets the Type of the current instance. (Inherited from Object)
LoadViewState(Object)	Loads the state of the values in the ParameterDataSourceExpression 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 ParameterDataSourceExpression object.
SetContext(Control, HttpContext, IQueryableDataSource)	Executes the expression by using the specified owner control, context, and data source.
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.

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)
