DataSourceExpressionCollection()

Initializes a new instance of the DataSourceExpression class.

Properties

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

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(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.
Equals(Object)	Determines whether the specified object is equal to the current object. (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.
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(Int32, Object) or IList.Add(Object) 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(Int32, Object) or IList.Add(Object) 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(Object) or IList.RemoveAt(Int32) 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(Object) or IList.RemoveAt(Int32) 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.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

ICollection.Count	Gets the number of elements contained in the StateManagedCollection collection. (Inherited from StateManagedCollection)
ICollection.IsSynchronized	Gets a value indicating whether the StateManagedCollection collection is synchronized (thread safe). This method returns `false` in all cases. (Inherited from StateManagedCollection)
ICollection.SyncRoot	Gets an object that can be used to synchronize access to the StateManagedCollection collection. This method returns `null` in all cases. (Inherited from StateManagedCollection)
IEnumerable.GetEnumerator()	Returns an iterator that iterates through the StateManagedCollection collection. (Inherited from StateManagedCollection)
IList.Add(Object)	Adds an item to the StateManagedCollection collection. (Inherited from StateManagedCollection)
IList.Clear()	Removes all items from the StateManagedCollection collection. (Inherited from StateManagedCollection)

IList.IndexOf(Object)	Determines the index of a specified item in the StateManagedCollection collection. (Inherited from StateManagedCollection)
IList.Insert(Int32, Object)	Inserts an item into the StateManagedCollection collection at the specified index. (Inherited from StateManagedCollection)
IList.IsFixedSize	Gets a value indicating whether the StateManagedCollection collection has a fixed size. This method returns `false` in all cases. (Inherited from StateManagedCollection)
IList.IsReadOnly	Gets a value indicating whether the StateManagedCollection collection is read-only. (Inherited from StateManagedCollection)
IList.Item[Int32]	Gets the IStateManager element at the specified index. (Inherited from StateManagedCollection)
IList.Remove(Object)	Removes the first occurrence of the specified object from the StateManagedCollection collection. (Inherited from StateManagedCollection)
IList.RemoveAt(Int32)	Removes the IStateManager element at the specified index. (Inherited from StateManagedCollection)
IStateManager.IsTrackingViewState	Gets a value indicating whether the StateManagedCollection collection is saving changes to its view state. (Inherited from StateManagedCollection)
IStateManager.LoadViewState(Object)	Restores the previously saved view state of the StateManagedCollection collection and the IStateManager items it contains. (Inherited from StateManagedCollection)
IStateManager.SaveViewState()	Saves the changes to the StateManagedCollection collection and each IStateManager object it contains since the time the page was posted back to the server. (Inherited from StateManagedCollection)
IStateManager.TrackViewState()	Causes the StateManagedCollection collection and each of the IStateManager objects it contains to track changes to their view state so they can be persisted across requests for the same page. (Inherited from StateManagedCollection)

Extension Methods
