So, how can you use GridView with callback paging without postbacks? What's
missing from the code and why shouldn't the code work? And where is the
documentation for avoiding this problem?

Hi,
The GridView disappers because it is empty. If you want to use a
callback to change the page set GridView's datasource in the page load
event handler. You don't need to process PageIndexChanging event, it
is not raised.

<asp:GridView ID="AuthorsGridView" runat="server" AllowPaging="True"
EnableSortingAndPagingCallbacks="True" PageSize="3">
......
</asp:GridView>

Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
If Not IsPostBack Then
bindDataToGridView()
End If

If Not IsCallback Then
......
AuthorsGridView.DataSource = ds
'AuthorsGridView.DataBind() Don't bind here!
End If
End Sub

Regards
