Paging is not working at all in the RAdGrid

[Perry]

I have a RADGRID running but it will not do paging. I believe I have the settings.  The ASPX setting are below.

<section id="Grid" class="Grid-container">
    <telerik:RadGrid ID="RadGridInvestigations"
        runat="server"
        AllowPaging="True"
        PageSize="10"
