[CLOSED] Adding FormPanel Items from Codebehind

[debarry]

I need to programatically add items to a FormPanel from code behind, in a DirectEvent.
I have this so far:

<ext:FormPanel ID="FormPanelIndex" runat="server" ButtonAlign="Right" Title="Classifica??o de Documentos">
    <Items>
        <ext:FieldSet ID="FieldSetIndex" runat="server" ColumnWidth="0.4" Title="Classifica??o" MarginSpec="10" ButtonAlign="Right">
            <Defaults>
                <ext:Parameter Name="Width" Value="240" />
                <ext:Parameter Name="LabelWidth" Value="80" />
            </Defaults>
            <Items>
                <ext:SelectBox ID="DDIdClass" runat="server" DisplayField="ClassTitulo" ValueField="IdClass" FieldLabel="Classifica??o" ondirectselect="DDIdClass_DirectSelect" >
                    <Store>
                        <ext:Store ID="Store3" runat="server" DataSourceID="SqlDataSourceClassList">
                            <Model>
                                <ext:Model ID="ModelClass" runat="server">
                                    <Fields>
                                        <ext:ModelField Name="IdClass" />
                                        <ext:ModelField Name="ClassTitulo" />
                                    </Fields>
                                </ext:Model>
                            </Model>            
                        </ext:Store>    
                    </Store>
                </ext:SelectBox>
                <ext:TextField ID="TbIdDoc" Name="IdVersao" runat="server" FieldLabel="#Doc" ReadOnly="True" />
                <ext:TextField ID="TbDocTitulo" Name="DocTitulo" runat="server" FieldLabel="Titulo" />
            </Items>                    
        </ext:FieldSet>
    </Items>
    <Buttons>
        <ext:Button ID="BtSave" runat="server" Icon="Disk" Text="Salvar" OnDirectClick="BtSave_OnDirectClick" />
    </Buttons>
</ext:FormPanel>

AND

<ext:GridPanel ID="GridPanel1" runat="server" ColumnWidth="0.6" MultiSelect="True">
    <Store>
        <ext:Store ID="Store1" runat="server" PageSize="25" DataSourceID="SqlDataSourceDocumentoList">
            <Model>
                <ext:Model ID="Model2" runat="server" IDProperty="IdVersao">
                    <Fields>
                        <ext:ModelField Name="IdVersao"/>
                        <ext:ModelField Name="DocTitulo" />
                        <ext:ModelField Name="VerNomeArquivo" />
                        <ext:ModelField Name="VerTamanho"/>
                        <ext:ModelField Name="VerDataCriacao" />
                        <ext:ModelField Name="VerNumeroVersao" />
                    </Fields>
                </ext:Model>
            </Model>
        </ext:Store>            
    </Store>
    <ColumnModel ID="ColumnModel1" runat="server">
        <Columns>
            <ext:Column ID="Column1" runat="server" Text="#" Width="50" Sortable="true" DataIndex="IdVersao"/>
            <ext:Column ID="Column2" runat="server" Text="Titulo" Width="300" Sortable="true" DataIndex="DocTitulo"/>
            <ext:Column ID="Column3" runat="server" Text="Nome Arquivo" Width="300" Sortable="true" DataIndex="VerNomeArquivo"/>
            <ext:Column ID="Column4" runat="server" Text="Tamanho" Width="100" Sortable="true" DataIndex="VerTamanho">
                <Renderer Format="FileSize" />
            </ext:Column>
            <ext:DateColumn ID="Column5" runat="server" Text="Data Cria??o" Width="80" Sortable="true" DataIndex="VerDataCriacao" Format="dd/MM/Y" />
            <ext:Column ID="Column6" runat="server" Text="Vers?o" Width="80" Sortable="true" DataIndex="VerNumeroVersao"/>
        </Columns>
    </ColumnModel>
    <BottomBar>
        <ext:PagingToolbar ID="PagingToolbar1" runat="server" DisplayInfo="false">
        </ext:PagingToolbar>
    </BottomBar>
    <Listeners>
        <SelectionChange Handler="if (selected[0]) { #{FormPanelIndex}.getForm().loadRecord(selected[0]); } App.direct.DE.CarregaDocumento();" />
    </Listeners>

</ext:GridPanel>

AND finally:

[DirectMethod]
public void CarregaDocumento()
{
    //CODE
}

I can manipulate the database from CarregaDocumento() section, but things like SqlDataSource.Databind() doesnt work...
What am I missing?

Thanks in advance!
