GridViewRowCollection Class

Note: This class is new in the .NET Framework version 2.0.

Represents a collection of GridViewRow objects in a GridView control.

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

public class GridViewRowCollection : ICollection, IEnumerable
public class GridViewRowCollection implements ICollection, IEnumerable
public class GridViewRowCollection implements ICollection, IEnumerable

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.

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

<script runat="server">

  void AuthorsGridView_RowCreated(Object sender, GridViewRowEventArgs e)
    if (e.Row.RowType == DataControlRowType.Footer)
      // Get the number of items in the Rows collection.
      int count = AuthorsGridView.Rows.Count;

      // If the GridView control contains any records, display 
      // the last name of each author in the GridView control.
      if (count > 0)
        Message.Text = "The authors are:<br>";
        foreach (GridViewRow row in AuthorsGridView.Rows)
          Message.Text += row.Cells[0].Text + "<br>";


    <form runat="server">
      <h3>GridViewRowCollection Example</h3>

            <asp:gridview id="AuthorsGridView" 
                <asp:boundfield datafield="au_lname"
                  headertext="Last Name"/>
                <asp:boundfield datafield="au_fname"
                  headertext="First Name"/>
            <asp:label id="Message" 
      <!-- This example uses Microsoft SQL Server and connects -->
      <!-- to the Pubs sample database.                        -->
      <asp:sqldatasource id="AuthorsSqlDataSource"  
        selectcommand="SELECT [au_lname], [au_fname] FROM [authors] WHERE [state]='CA'"
        connectionstring="server=localhost;database=pubs;integrated security=SSPI"
