asp.net - Accessing gridview from infile javascript aspx.net, paging issue -


so here's situation:

i've got grid:

    <asp:gridview id="productgrid" runat="server" allowsorting="true"      allowpaging="true" pagesize="20"      onpageindexchanging="pageindexchanged" pagersettings-visible="false"     autogeneratecolumns="false" onsorting="sort">

and i'm accessing this: 

    var grid = document.getelementbyid("<%= productgrid.clientid %>");

which works, that's fine, problem is, when go grid.row.length, 21, grid bound several hundred elements, problem it's looking @ first page, how @ rest of data?

i want iterate through whole table. yes i'm sure table has been loaded values before javascript executed, values on page load , script on button click.

thanks help
