I am using a radgrid and some GridDropDownColumns for displaying possible values when the user selects the edit command button. The problem is that the grid is displaying some values as it is supposed and others not, I am binding the grid programmatically at the code behind and sending a dataset with the values for the Master Table and for the drop down columns. The problem is only in the display, in edit mode the grid is working fine, I'm able to show the possible values in the columns as wondered.

here is the code...

aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"

        GridLines="None" MasterTableView-NoMasterRecordsText="No hay registros que mostrar">

        <MasterTableView DataKeyNames="ProductoId" Name="Productos" EditMode="InPlace">

        <Columns>

        <telerik:GridNumericColumn UniqueName="columnProductoId" HeaderText="ProductoId" DataField="ProductoId" Visible="false"></telerik:GridNumericColumn>

        <telerik:GridDropDownColumn UniqueName="columnTipoProducto"></telerik:GridDropDownColumn>

        <telerik:GridDropDownColumn UniqueName="columnPaisMoneda"></telerik:GridDropDownColumn>

        <telerik:GridDropDownColumn UniqueName="columnEstado"></telerik:GridDropDownColumn>

        <telerik:GridDropDownColumn UniqueName="columnOperador"></telerik:GridDropDownColumn>

        <telerik:GridBoundColumn UniqueName="columnDescripcion" HeaderText="Descripcion" DataField="Descripcion">

        </telerik:GridBoundColumn>

        <telerik:GridNumericColumn  UniqueName="columnValor" HeaderText="Valor" DataField="Valor">

        </telerik:GridNumericColumn>

        <telerik:GridDateTimeColumn UniqueName="columnFechaRegistro" HeaderText="Fecha de Registro" DataField="FechaRegistro">

        </telerik:GridDateTimeColumn>

        <telerik:GridEditCommandColumn UniqueName="EditCommandColumn" EditText="Editar">

        </telerik:GridEditCommandColumn>

        <telerik:GridButtonColumn CommandName="Delete" ConfirmDialogType="RadWindow" ConfirmText="Está seguro de que desea eliminar este producto?" Text="Eliminar" UniqueName="DeleteColumn">

        </telerik:GridButtonColumn>

        </Columns>

            <RowIndicatorColumn>

                <HeaderStyle Width="20px" />

            </RowIndicatorColumn>

            <ExpandCollapseColumn>

                <HeaderStyle Width="20px" />

            </ExpandCollapseColumn>

        </MasterTableView>

    </telerik:RadGrid>

vb code behind:

        Try

            'here is where i send the dataset with all the DataTable               needed

1. A couple of dropdown lists in my RadGrid
2. A multilingual application, such that the ViewModel provides an object for each property, but getting the display text requires a translation step to the user's language - can't just display the ViewModel property directly.  I guess I COULD change this to have one property on the ViewModel that returns the string display value and another that returns the integer underlying value, but that seems messy to me - would much prefer a solution like IValueConverter to convert between the ViewModel and the displayed value based on the type of the property.  Is that the "best practice"?  Will that cause extra server round-trips, because the property that the client side form binds to requires server side logic to execute in order to produce its value?
3. A form template for my EditForm
