Hello

I am trying to add second row to GridPanel's rows, the same way it is done in GridPanel-SqlDataSource example. When I copy/paste the following to my GridPanel, I start getting "Only one items available" error:

             <View>
                <ext:GridView ID="GridView1" runat="server" EnableRowBody="true">
                    <GetRowClass Handler="rowParams.body = '<p>'+record.data.MyLongField +'</p>'; return 'x-grid3-row-expanded';" />
                </ext:GridView>
            </View>
The error message highlights the following string:
Line 244:    <ext:GridPanel ID="GridPanel1" runat="server" Height="400" StoreID="" StripeRows="true
I bind GridPanel in my codebehind like this:
                MyStore.DataSource = dao.GetData();
                MyStore.DataBind();
                GridPanel1.StoreID = "MyStore";
                GridPanel1.DataBind();
Can anybody help?
