DetailsViewRowCollection Class

Represents a collection of DetailsViewRow objects in a DetailsView control.


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

public class DetailsViewRowCollection : ICollection, 

The DetailsViewRowCollection type exposes the following members.

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

Public propertyCountGets the number of items in the DetailsViewRowCollection object.
Public propertyIsReadOnlyGets a value indicating whether the rows in the DetailsViewRowCollection object can be modified.
Public propertyIsSynchronizedGets a value indicating whether the DetailsViewRowCollection object is synchronized (thread safe).
Public propertyItemGets the DetailsViewRow object from the collection at the specified index.
Public propertySyncRootGets the object used to synchronize access to the collection.

Public methodCopyToCopies all the items from this DetailsViewRowCollection object to the specified Array object, starting at the specified index in the Array.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorReturns an enumerator that contains all DetailsViewRow objects in the DetailsViewRowCollection object.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodAsParallelEnables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension MethodAsQueryableConverts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension MethodCast<TResult>Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodOfType<TResult>Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)

Explicit interface implemetationPrivate methodICollection.CopyToInfrastructure. Copies all the items from this DetailsViewRowCollection object to the specified Array object, starting at the specified index in the Array.

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.


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.

<%@ page language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<script runat="server">

  void SubmitButton_Click(Object sender, EventArgs e)

    // Use the Count property to determine whether the
    // Rows collection contains any item.
    if (ItemDetailsView.Rows.Count > 0)
      // 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/>";
      MessageLabel.Text = "No items.";
