You should follow the steps: 1- Define a asp:ObjectDataSource ID="dgDataSource" for your datagrid. 2- Define a asp:ObjectDataSource ID="cbDataSource" for your ComboBox. NOTE: Each of these 2 data sources are connected to a 2 different Models.

<dx:ASPxGridView ID="myListGridView" ClientInstanceName="myListGridView" DataSourceID="dgDataSource"
    runat="server" AutoGenerateColumns="False" KeyFieldName="**field1Ofdg**"
    OnRowUpdated="myListGridView_RowUpdated">

<Columns>
    <dx:GridViewDataColumn FieldName="**field1Ofdg**" Caption="Code" Width="30%" >
        </dx:GridViewDataColumn>
    <dx:GridViewDataComboBoxColumn FieldName="**field2Ofdg**" ReadOnly="false" >  
        <PropertiesComboBox DataSourceID="cbDataSource" TextField="**LabelOfcb**" ValueField="**IdOfcb**"  >
        </PropertiesComboBox>
    </dx:GridViewDataComboBoxColumn>                   
</Columns>
</dx:ASPxGridView>

thes are the definitions for your data sources:

<asp:ObjectDataSource ID="dgDataSource" runat="server" SelectMethod="GetMyDataForGridFunction" 
        UpdateMethod="UpdateDataForGridFunction" TypeName="namespace1"></asp:ObjectDataSource>

     <asp:ObjectDataSource ID="cbDataSource" runat="server" SelectMethod="GetMyDataForComboBoxFunction"
         TypeName="namespace2"></asp:ObjectDataSource>

NOTE: field1Ofdg and field1Ofdg are properties of Model1 Model of the grid. LabelOfcb and IdOfcb are properties of Model2 model of the ComboBox.

Keep me updated if it works fine to you :)

Have a look at this... it has a simple layout and uses a dropdown rather than combo but can be adapted. If you run into any problems then let us know.... but supplying some code would be easier.
