Remarks

You can use the DataPagerFieldCollection class to programmatically manage a set of DataPagerField objects. Note that it is more typical to define these fields declaratively instead of programmatically.

You can access the properties and methods of the DataPagerFieldCollection class through the DataPager.Fields property. You can add, insert, and remove DataPagerField objects by using the appropriate methods of the DataPagerFieldCollection class. To programmatically retrieve DataPagerField objects from a collection, do one of following:

Use the indexer to get a single DataPagerField object from the collection.
Use the GetEnumerator method to create an object that implements System.Collections.IEnumerator, which you can then use to get items from the collection.

The Count property gets the total number of items in the collection. It is typically used to determine the upper bound of the collection. You can add items and remove items in the collection by using the Add, Insert, Remove, and RemoveAt methods.

Constructors

DataPagerFieldCollection(DataPager)

Initializes a new instance of the DataPagerFieldCollection class.

Properties

Count	Gets the number of elements contained in the StateManagedCollection collection. (Inherited from StateManagedCollection)
Item[Int32]	Gets the DataPagerField object that is at the specified index in the collection.

Methods

Add(DataPagerField)	Appends the specified DataPagerField object to the collection.
Clear()	Removes all items from the StateManagedCollection collection. (Inherited from StateManagedCollection)
CloneFields(DataPager)	Creates a copy of the current collection.
Contains(DataPagerField)	Determines whether the DataPagerFieldCollection collection contains the specified DataPagerField object.
CopyTo(Array, Int32)	Copies the elements of the StateManagedCollection collection to an array, starting at a particular array index. (Inherited from StateManagedCollection)
CopyTo(DataPagerField[], Int32)	Copies the complete DataPagerFieldCollection collection to a one-dimensional Array object, starting at the specified index of the target array.
CreateKnownType(Int32)	Creates a default instance of the DataPagerField type that is identified by the provided index.
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 DataPagerField types that the DataPagerFieldCollection collection can contain.
GetType()	Gets the Type of the current instance. (Inherited from Object)
IndexOf(DataPagerField)	Gets the index of a specific DataPagerField object in the collection.
Insert(Int32, DataPagerField)	Inserts the specified DataPagerField object into the DataPagerFieldCollection collection 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()	Performs additional processing after all items are removed from the collection.
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)	Performs additional processing after an item is added to the collection.
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)	Performs additional processing after an item is removed from the collection.
OnValidate(Object)	Verifies that the specified object is a DataPagerField object.
Remove(DataPagerField)	Removes the specified DataPagerField object from the DataPagerFieldCollection collection.
RemoveAt(Int32)	Removes the DataPagerField object at the specified index from the DataPagerFieldCollection collection.
SetDirty()	Forces the entire StateManagedCollection collection to be serialized into view state. (Inherited from StateManagedCollection)
SetDirtyObject(Object)	Instructs the specified DataPagerField object to record its complete state to view state, instead of recording only changed information.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Events

FieldsChanged

Occurs when the fields in the DataPagerFieldCollection collection change.

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.Contains(Object)	Determines whether the StateManagedCollection collection contains a specific value. (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

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
