RadComboBox row-dependent data on Grid

[archimede]

I have an aspx page with a Grid. Each row on grid is identified by an id (idAzienda).
Each row on grid has also a column with a radComboBox (RepartoRadComboBox). I want this radComboBox to have a datasource (ObjectDataSourceRepartiAzienda) dependent on row parameter idAzienda.
How can I set this "dynamical" datasource?

My grid is:

<telerik:RadGrid ID="RadGridAziendeForUser" runat="server" DataSourceID="ObjectDataSourceAziendeUtente"
                EnableEmbeddedSkins="False" GridLines="None" Skin="MachinaWeb" AllowAutomaticUpdates="True"

                OnItemCommand="RadGridAziendeForUser_ItemCommand" OnItemDataBound="RadGridAziendeForUser_ItemDataBound"
                AllowPaging="True" PageSize="5">

Hello,

If you want to populate RadComboBox based on the field 'idAzienda' (which is DataKeyValue), then one suggestion is storing the keyvalue in a session variable and in ObjectDataSource, populate the RadComboBox  by using SessionParameter which identifies the name stored in the current Session object.

C#:


protected void RadGridAziendeForUser_ItemDataBound(object sender, GridItemEventArgs e)
   {
      if (e.Item is GridEditableItem && e.Item.IsInEditMode)
       {
           GridEditableItem editItem = (GridEditableItem)e.Item;
           Session["idAzienda"] = editItem.GetDataKeyValue("idAzienda").ToString(); // store the DataKeyValue in a Session variable
           RadComboBox combo = (RadComboBox)editItem.FindControl("RepartoRadComboBox");
           combo.DataSourceID = "ObjectDataSourceRepartiAzienda";
           combo.DataTextField = " ";// assign your DataTextField
           combo.DataValueField = "";// assign your DataValueField
       }
   }

DataSource:

<asp:ObjectDataSource ID="ObjectDataSourceRepartiAzienda" runat="server"
                SelectMethod="getAllByAzienda" TypeName="MachinaWeb.Services.BO_Reparto">
       <SelectParameters>
            <asp:SessionParameter SessionField="idAzienda" Name="idAzienda" />
       </SelectParameters>
</asp:ObjectDataSource>

Hope this helps.
Princy.
