Using a Store from Code-Behind after DataBinding

[csharpdev]

Hi,

i want to access a Store "if its possible" via the code behind, instead of passing the ExtraParams.

ASPX

            
<ext:ComboBox ID="cbMonthTheme" runat="server" Editable="true" TypeAhead="true" Mode="Local"
                AnchorHorizontal="100%" ForceSelection="true" TriggerAction="All" SelectOnFocus="true"
                DisplayField="NAME" ValueField="ID_GUI">
                <DirectEvents>
                    <Select OnEvent="UpdateAreaModuleSize" />
                </DirectEvents>
                <Store>
                    <ext:Store runat="server" ID="storeMonthTheme">
                        <Reader>
                            <ext:JsonReader>
                                <Fields>
                                    <ext:RecordField Name="NAME" Type="String" Mapping="NAME" />
                                    <ext:RecordField Name="ID_GUI" Type="String" Mapping="ID_GUI" />
                                </Fields>
                            </ext:JsonReader>
                        </Reader>
                    </ext:Store>
                </Store>
            </ext:ComboBox>

Whats workings: .DataSource and .DataBind with LINQ then DirectEvent:

                    <Select OnEvent="UpdateMonthTheme">
                        <ExtraParams>
                            <ext:Parameter Name="AreaModuleData" Value="#{storeAreaModule}.getAt(#{cbAreaModule}.selectedIndex).data"
                                Mode="Raw" Encode="true" />
                        </ExtraParams>
                    </Select>

and Deserialize it again in Code-Behind:

protected void UpdateMonthTheme(object sender, DirectEventArgs e)
        {
            ZSD_GDA_MOD data = JSON.Deserialize<ZSD_GDA_MOD>(e.ExtraParams["AreaModuleData"]);
      }

Question: What we've trying to do is instead of deserialzing to access to object in the store directly from binding again.
We have the .SelectedIndex of a Combobox, now with the Index to receive back the Item/Object from the Store.

Something like this, would be very powerful:

protected void UpdateMonthTheme(object sender, DirectEventArgs e)
        {
            ZSD_GDA_MOD data = (ZSD_GDA_MOD)storeMonthTheme.Items[cbMonthTheme.SelectedIndex];
      }

Sure this makes only sense on static select data of combo boxes, not for ajax edit/changes postbacks.
We dont want to keep extra arrays or lists only with id and value because, we straight want to stick to the Stores with our OR Mapping (Linq-to-SQL).

Hi,

There is no collection like Items on server side.
