PageIndexChanged Event

DetailsView.PageIndexChanged Event

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

Occurs when the value of the PageIndex property changes after a paging operation.

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

public event EventHandler PageIndexChanged
/** @event */
public void add_PageIndexChanged (EventHandler value)

/** @event */
public void remove_PageIndexChanged (EventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The DetailsView control raises the PageIndexChanged event when a pager button (a button with its CommandName property set to "Page") within the control is clicked, but after the DetailsView control handles the paging operation. This allows you to provide an event handler that performs a custom routine whenever this event occurs.

NoteNote

This event is not raised when you programmatically set the PageIndex property.

Pager buttons are usually located in the pager row of a DetailsView control. This event is often used to synchronize a DetailsView control with a GridView control or to set the behavior of the DetailsView control after a paging operation.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use the PageIndexChanged event to return the DetailsView to read-only mode when the user navigates to another record.


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

<script runat="server">

  void CustomerDetailView_PageIndexChanged(Object sender, EventArgs e)
  {
    // By default, if the DetailsView control is in edit mode and
    // user navigates to another page, the DetailsView control
    // remains in edit mode. In this example, the ChangeMode 
    // method is used to put the DetailsView control in read-only  
    // mode whenever the user navigates to another record.
      CustomerDetailView.ChangeMode(DetailsViewMode.ReadOnly);
  }

</script>
