[CLOSED] GridPanel - CheckboxSelectionModel - Set selected rows in a DirectEvent

[jamesand]

Hi again, I have a GridPanel with a CheckboxSelectionModel. When the gridview is loaded no row is setted to selected.
But, I have a button to set the selected rows.

Here is the gridpanel:

<ext:GridPanel 
                            runat="server" 
                            ID="GridPanel1" 
                            Frame="true"
                            MaxHeight="600"
                            MinHeight="300" >
                            <Store>
                                <ext:Store 
                                    ID="Store1" 
                                    runat="server" 
                                    RemoteSort="true" ClearOnPageLoad="true"

                                            <Fields>

                                                <ext:ModelField Name="ID_CLIENTE" Type="Int" />

                                </ext:GridFilters>

                            <SelectionModel>
                                <ext:CheckboxSelectionModel ID="CheckboxSelectionModel1" runat="server" Mode="Multi" />
                            </SelectionModel>       
                            <Buttons>
                                <ext:Button ID="btnRecuperarListaCorreo" runat="server" Text="Recuperar clientes en la lista de correo" Icon="EmailOpen">
                                    <DirectEvents>
                                        <Click OnEvent="RecuperarListaCorreo"></Click>
                                    </DirectEvents>
                                </ext:Button>
                            </Buttons>
                        </ext:GridPanel>

And the direct event:

Public Sub RecuperarListaCorreo(ByVal sender As Object, ByVal e As Ext.Net.DirectEventArgs)

        Dim sm As CheckboxSelectionModel = GridPanel1.GetSelectionModel()

        Try

            Dim InterfazBD As New Negocio.InterfazClientes()

            Dim listaCorreoGuardada As Object = InterfazBD.RecuperarListaCorreo()

            For Each cliente In listaCorreoGuardada
                CheckboxSelectionModel1.SelectedRows.Add(New SelectedRow(cliente.ID_CLIENTE.ToString))
            Next

        Catch ex As Exception
            MostrarPanelMensaje("alert alert-error", "Error enviando el newsletter. Error: " & ex.Message)
        End Try

    End Sub

But no rows are checked. The thing is that I put that code in the page_load, it set the selected rows fine.

Any ideas?

Hi @jamesand,

If you change a SelectedRows collection during a DirectEvent, please call a CheckboxSelectionModel's UpdateSelection method to get the changes applied. As here:

Ok it works fine now. Thank you Daniil.
