asp.net - OutOfMemoryException Binding ObjectDataSource to GridView -


i'm trying use gridview show table pulled sql server. log of events. i've placed gridview control on page along objectdatasource control. i've configured :

<%@ page language="vb" %>  <!doctype html public "-//w"     "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html> <head>     <title></title> </head> <body>     <form id="form1" method="post" runat="server">     <asp:gridview id="gvhistory" runat="server" datasourceid="dshistory">     </asp:gridview>     <asp:objectdatasource id="dshistory" runat="server" selectmethod="gethistoryrows"         typename="aspdotnetstorefrontadmin.roiimporthistory"></asp:objectdatasource>     </form> </body> </html>

i've created class in app_code folder follows:

imports system.data  namespace aspdotnetstorefrontadmin      public class roiimporthistory          public shared function gethistoryrows() datatable              dim localdatatable new datatable              localdatatable.columns.add()             localdatatable.columns.add()             localdatatable.columns.add()             localdatatable.rows.add(new object() {"hi", "hi2", "hi3"})              return localdatatable          end function     end class  end namespace

however, following exception when try run this:

what going wrong? thought doing pretty basic thing here. i've tried lots of different options , know page works fine if remove either gridview or objectdatasource. if bind datatable directly gridview things work correctly.

my purpose true pagination along filtering. given working more than't want load datatable every time page loads.

i've referenced this , this no avail.

note: found code runs fine loaded site on same server in same application pool. therefore believe has configuration issue.

i think may using objectdatasource incorrectly here.

my understanding of objectdatasource give type records, , "select method" return collection of record data type.

alternately, use entity framework objectdatasource.
