Datagrid Paging

[LauraCairns]

I've got the below datagrid set-up below and Im trying to get the paging wired up. The correct numbers are coming back based on the amount on pages there should be however the on-click event of each page number isn't working. Does anyone know which event I use and what code I need to add to achieve this? Thanks for your help.

<asp:datagrid id="dgAppForms" runat="server" Width="600px" CssClass="reg" BackColor="White" DataKeyField="Id"
CellPadding="4" BorderColor="White" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"
Font-Names="pages">
<AlternatingItemStyle ForeColor="#061444" BackColor="#E4E4E4"></AlternatingItemStyle>
<ItemStyle ForeColor="#061444" BackColor="#EEEEEE"></ItemStyle>
<HeaderStyle Font-Names="Verdana" Wrap="False" ForeColor="White" CssClass="regtitle2" BackColor="#0D257B"></HeaderStyle>
<FooterStyle Wrap="False" ForeColor="White"></FooterStyle>
<Columns>
<asp:BoundColumn Visible="False" DataField="Id" HeaderText="VacancyChangeID">
<HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle"></HeaderStyle>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle"></ItemStyle>
<FooterStyle Wrap="False"></FooterStyle>
</asp:BoundColumn>
<asp:BoundColumn DataField="FileName" SortExpression="AppFormName" ReadOnly="True" HeaderText="Application Form Name">
<HeaderStyle Font-Bold="True" HorizontalAlign="Center" CssClass="regtitle" VerticalAlign="Middle"></HeaderStyle>
<ItemStyle HorizontalAlign="Left" VerticalAlign="Middle"></ItemStyle>
<FooterStyle Wrap="False"></FooterStyle>
</asp:BoundColumn>
</Columns>
<PagerStyle VerticalAlign="Middle" HorizontalAlign="Center" ForeColor="White" BackColor="#0D257B"
Wrap="False" Mode="NumericPages"></PagerStyle>
</asp:datagrid>
