Property Value
The index of the row being edited.
Use the NewEditIndex property to determine the index of the row being edited. The row index is often used to retrieve this row from the Rows collection of the GridView control, which allows you to access the row's properties.
The following example demonstrates how to use the NewEditIndex property to determine the index of the row being edited.
<%@ Page language="VB" %>
<script runat="server">
Sub CustomersGridView_RowEditing(ByVal sender As Object, ByVal e As GridViewEditEventArgs)
' Get the country for the row being edited. For this example, the
' country is contained in the seventh column (index 6).
Dim country As String = CustomersGridView.Rows(e.NewEditIndex).Cells(6).Text
' For this example, cancel the edit operation if the user attempts
' to edit the record of a customer from the United States.
If country = "USA" Then
' Cancel the edit operation.
e.Cancel = True
Message.Text = "You cannot edit this record."
Else
Message.Text = ""
End If
End Sub
