Constructors

	Name	Description
	DataSourceExpressionCollection()	Initializes a new instance of the DataSourceExpression class.

Properties

	Name	Description
	Context	Gets the HttpContext instance of the DataSourceExpressionCollection class.
	Count	Gets the number of elements contained in the StateManagedCollection collection.(Inherited from StateManagedCollection.)
	Item[Int32]	Gets or sets the data source expression object at a specified index.
	Owner	Gets the owner control.

Methods

	Name	Description
	Add(DataSourceExpression^)	Adds a data source expression object to a DataSourceExpressionCollection object at the specified index.
	Clear()	Removes all items from the StateManagedCollection collection.(Inherited from StateManagedCollection.)
	Contains(DataSourceExpression^)	Determines whether a DataSourceExpressionCollection object contains a specific data source expression object.
	CopyTo(Array^, Int32)	Copies the elements of the StateManagedCollection collection to an array, starting at a particular array index.(Inherited from StateManagedCollection.)
	CopyTo(array<DataSourceExpression^>^, Int32)	Copies elements of the DataSourceExpressionCollection object to an array, starting at a particular index.
	CreateKnownType(Int32)	Creates an instance of a data source expression object.(Overrides StateManagedCollection::CreateKnownType(Int32).)
	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.)
	GetEnumerator()	Returns an iterator that iterates through the StateManagedCollection collection.(Inherited from StateManagedCollection.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetKnownTypes()	Gets an array of data source expression objects that the DataSourceExpressionCollection object can contain.(Overrides StateManagedCollection::GetKnownTypes().)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	IndexOf(DataSourceExpression^)	Gets the index of a specified data source expression object in the DataSourceExpressionCollection object.
	Insert(Int32, DataSourceExpression^)	Inserts a data source expression object into an DataSourceExpressionCollection object at the specified index.
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	OnClear()	When overridden in a derived class, performs additional work before the Clear method removes all items from the collection.(Inherited from StateManagedCollection.)
	OnClearComplete()	When overridden in a derived class, performs additional work after the Clear method finishes removing all items from the collection.(Inherited from StateManagedCollection.)
	OnInsert(Int32, Object^)	When overridden in a derived class, performs additional work before the IList::Insert or IList::Add method adds an item to the collection.(Inherited from StateManagedCollection.)
	OnInsertComplete(Int32, Object^)	When overridden in a derived class, performs additional work after the IList::Insert or IList::Add method adds an item to the collection.(Inherited from StateManagedCollection.)
	OnRemove(Int32, Object^)	When overridden in a derived class, performs additional work before the IList::Remove or IList::RemoveAt method removes the specified item from the collection.(Inherited from StateManagedCollection.)
	OnRemoveComplete(Int32, Object^)	When overridden in a derived class, performs additional work after the IList::Remove or IList::RemoveAt method removes the specified item from the collection.(Inherited from StateManagedCollection.)
	OnValidate(Object^)	When overridden in a derived class, validates an element of the StateManagedCollection collection.(Inherited from StateManagedCollection.)
	Remove(DataSourceExpression^)	Removes the first occurrence of the specified data source expression object from the DataSourceExpressionCollection object.
	RemoveAt(Int32)	Removes a data source expression object at a specified index from the DataSourceExpressionCollection object.
	SetDirty()	Forces the entire StateManagedCollection collection to be serialized into view state. (Inherited from StateManagedCollection.)
	SetDirtyObject(Object^)	Marks a specified data source expression object as having changed since the last load or save operation from view state.(Overrides StateManagedCollection::SetDirtyObject(Object^).)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)
