Property Value

The index of the record being deleted from the data source.

Use the RowIndex property to determine the index of the record being deleted from the data source. The row index corresponds to the page index of the record being deleted.

The following example demonstrates how to use the RowIndex property to determine the index of the record being deleted.


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

<script runat="server">

  void EmployeeFormView_ItemDeleting(Object sender, FormViewDeleteEventArgs e)
  {
    // Get the employee ID, name, and job title from the Keys and Values
    // properties.
    String keyValue = e.Keys["EmployeeID"].ToString();
    String employeeName = e.Values["FirstName"].ToString() +
      " " + e.Values["LastName"].ToString();
    String title = e.Values["Title"].ToString();

    // Cancel the delete operation if the user attempts to 
    // delete a protected record. In this example, records for
    // employees with a "Sales Manager" job title are protected.
    if (title.Equals("Sales Manager"))
    {
      e.Cancel = true;
      MessageLabel.Text = "You cannot delete record " +
        e.RowIndex.ToString() + ". " + employeeName +
        " (Employee Number " + keyValue.ToString() +
        ") is protected.";
    }

  }
