How can I add a particular column q this selected, via java-script? I am using ext.net.

        <script>
        var sumCheck= function () {
            var resultSum;

          /* todo loop selectedrows
             resultSum += column(field_value); */;

            alert(resultSum);
        };
    </script>

 <ext:GridPanel runat="server" ID="grid1" Height="250px" Frame="true" StoreID="dsGrid1">
                        <ColumnModel runat="server">
                            <Columns>
                                <ext:NumberColumn runat="server" DataIndex="field_value" Format=",0.00" Align="Right"/>                             
                            </Columns>
                        </ColumnModel>
                        <SelectionModel>
                            <ext:CheckboxSelectionModel runat="server" Mode="Multi">
                                <Listeners>
                                    <SelectionChange Fn="sumCheck()" />
                                </Listeners> 
                            </ext:CheckboxSelectionModel>
                        </SelectionModel>                       
</ext:GridPanel>

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            this.Store2.DataSource = new object[]
            {
                new object[] { 'A', 20 },
                new object[] { 'B', 52 },
                new object[] { 'C', 36 }
            };
            this.Store2.DataBind();

        }
    }
