GridViewRowCollection Class

 

Represents a collection of GridViewRow objects in a GridView control.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

System.Object
  System.Web.UI.WebControls.GridViewRowCollection

public class GridViewRowCollection : ICollection, IEnumerable

NameDescription
System_CAPS_pubmethodGridViewRowCollection(ArrayList)

Initializes a new instance of the GridViewRowCollection class using the specified System.Collections.ArrayList object.

NameDescription
System_CAPS_pubpropertyCount

Gets the number of items in the GridViewRowCollection object.

System_CAPS_pubpropertyIsReadOnly

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

System_CAPS_pubpropertyIsSynchronized

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

System_CAPS_pubpropertyItem[Int32]

Gets the GridViewRow object at the specified index.

System_CAPS_pubpropertySyncRoot

Gets the object used to synchronize access to the collection.

NameDescription
System_CAPS_pubmethodCopyTo(GridViewRow[], Int32)

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

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetEnumerator()

Returns an enumerator that contains all GridViewRow objects in the GridViewRowCollection.

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodICollection.CopyTo(Array, Int32)

This API supports the product infrastructure and is not intended to be used directly from your code. For a description of this member, see CopyTo.

NameDescription
System_CAPS_pubmethodAsParallel()

Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)

System_CAPS_pubmethodAsQueryable()

Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)

System_CAPS_pubmethodCast<TResult>()

Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)

System_CAPS_pubmethodOfType<TResult>()

Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)

The GridViewRowCollection class is used to store and manage a collection of GridViewRow objects in a GridView control. Each row in a GridView control is represented by a GridViewRow object. The GridView control stores all of its data rows in the Rows collection.

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

  • Use the Item indexer to directly retrieve a GridViewRow object 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 System.Array object, 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

The following example demonstrates how to iterate through the Rows collection of a GridView control and display the values of a column on the page.

      int count = AuthorsGridView.Rows.Count;

      // If the GridView control contains any records, display 
      // the last name of each author in the GridView control.
