Remarks

The DetailsViewRowCollection class is used to store and manage a collection of DetailsViewRow objects in a DetailsView control. Each row in a DetailsView control is represented by a DetailsViewRow object. The DetailsView control uses the DetailsViewRowCollection class for its Rows property.

Note

The Rows property contains only the data rows. To access the header row, footer row, top pager row, and bottom pager row, use the HeaderRow, FooterRow, TopPagerRow, and BottomPagerRow properties, respectively.

The DetailsViewRowCollection class supports several ways to access the items in the collection:

  • Use the Item[Int32] indexer to directly retrieve a DetailsViewRow object from the collection at a specific zero-based index.

  • Use the GetEnumerator method to retrieve an enumerator that can be used to iterate through the collection.

  • Use the CopyTo method to copy the items in the collection into an array, which can then be used to access the items in the collection.

To determine the total number of items in the collection, use the Count property.

Constructors

DetailsViewRowCollection(ArrayList)

Initializes a new instance of the DetailsViewRowCollection class using the specified ArrayList object.

Properties

Count

Gets the number of items in the DetailsViewRowCollection object.

IsReadOnly

Gets a value indicating whether the rows in the DetailsViewRowCollection object can be modified.

IsSynchronized

Gets a value indicating whether the DetailsViewRowCollection object is synchronized (thread safe).

Item[Int32]

Gets the DetailsViewRow object from the collection at the specified index.

SyncRoot

Gets the object used to synchronize access to the collection.

Methods

CopyTo(DetailsViewRow[], Int32)

Copies all the items from this DetailsViewRowCollection object to the specified Array object, starting at the specified index in the Array.

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetEnumerator()

Returns an enumerator that contains all DetailsViewRow objects in the DetailsViewRowCollection object.

GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()

Returns a string that represents the current object.

(Inherited from Object)

Explicit Interface Implementations

ICollection.CopyTo(Array, Int32)

Copies all the items from this DetailsViewRowCollection object to the specified Array object, starting at the specified index in the Array.

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.

AsParallel(IEnumerable)

Enables parallelization of a query.

AsQueryable(IEnumerable)

Converts an IEnumerable to an IQueryable.
