Public Overridable ReadOnly Property Rows As GridViewRowCollection
Dim instance As GridView
Dim value As GridViewRowCollection
value = instance.Rows

Property Value
A GridViewRowCollection that contains all the data rows in a GridView control.
The Rows property (collection) is used to store the data rows in a GridView control. The GridView control automatically populates the Rows collection by creating a GridViewRow object for each record in the data source and then adding each object to the collection. This property is commonly used to access a specific row in the control or to iterate though the entire collection of rows.
.gif) Note |
|---|
| Only rows with their RowType property set to DataControlRowType.DataRow are stored in the Rows collection. The GridViewRow objects that represent the header, footer, and pager rows are not included in the collection. |
The following code example demonstrates how to use the Rows collection to access the row being edited in a GridView control. After a row is updated, a message is displayed to indicate that the update was successful.
<%@ Page language="VB" %>
<script runat="server">
Sub CustomersGridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)
' Clear the message label when the user enters edit mode.
If e.CommandName = "Edit" Then
Message.Text = ""
End If
End Sub
Sub CustomersGridView_RowUpdated(ByVal sender As Object, ByVal e As GridViewUpdatedEventArgs)
' The update operation was successful. Retrieve the row being edited.
Dim index As Integer = CustomersGridView.EditIndex
Dim row As GridViewRow = CustomersGridView.Rows(index)
' Notify the user that the update was successful.
Message.Text = "Updated record " & row.Cells(1).Text + "."
End Sub
Sub CustomersGridView_RowCancelingEdit(ByVal sender As Object, ByVal e As GridViewCancelEditEventArgs)
' The update operation was canceled. Display the appropriate message.
Message.Text = "Update operation canceled."
End Sub
