public class DetailsViewRowCollection : ICollection, IEnumerable

NameDescription
System_CAPS_pubmethodDetailsViewRowCollection(ArrayList)

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

NameDescription
System_CAPS_pubpropertyCount

Gets the number of items in the DetailsViewRowCollection object.

System_CAPS_pubpropertyIsReadOnly

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

System_CAPS_pubpropertyIsSynchronized

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

System_CAPS_pubpropertyItem[Int32]

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

System_CAPS_pubpropertySyncRoot

Gets the object used to synchronize access to the collection.

NameDescription
System_CAPS_pubmethodCopyTo(DetailsViewRow[], Int32)

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

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 DetailsViewRow objects in the DetailsViewRowCollection object.

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

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 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.

System_CAPS_noteNote

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 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.

The following code example demonstrates how to iterate through the DetailsViewRow objects in the Rows collection of a DetailsView control. The value of each row is then displayed on the page.

    {
      // Iterate through the Rows collection and display
      // the value of each field.
      MessageLabel.Text = "The row values are: <br/><br/>";

      foreach (DetailsViewRow row in ItemDetailsView.Rows)
      {
        // Use the Text property to access the value of 
        // each cell. In this example, the cells in the 
        // first column (index 0) contains the field names, 
        // while the cells in the second column (index 1)
        // contains the field value. 
        MessageLabel.Text += row.Cells[0].Text + " = " +
          row.Cells[1].Text + "<br/>";
      }
    }
    else
    {
      MessageLabel.Text = "No items.";
    }

  }
