[CLOSED] Load MultiSelectCombobox during button click direct event

[OSYS_FMS]

Hi,
I have a panel with many multiselect comboboxes. I am trying to make this panel delay load itself using a hidden button. Here is how I declared the comboboxes

<ext:Panel ID="OuterPanel" runat="server" AutoHeight="true" AutoWidth="true" border="false" IDMode="Explicit" ClientID="OuterPanel" >
<Content>
<ext:FormPanel runat="server" border="true" LabelAlign="Top" ColumnWidth="1" ID="cntFuelFilter" Title="Filters" ButtonAlign="Center" height="500px" autowidth="true" PaddingSummary="5px 20px 5px 5px">
    <items>       
                <ext:multicombo ID="ddlFleetType" runat="server" Delimiter="," fieldlabel="Fleet Type" IDMode="Explicit" ClientID="ddlFleetType" LabelCls="OSyS_WP_Label OSyS_WP_FuelFilter_Label"
                   AnchorHorizontal="95%" ValueField="IDENTIFIER" DisplayField="IDENTIFIER" Editable="false" Cls="OSyS_WP_DropDownList OSyS_WP_FuelFilter_DropDownList" >
                    <store>
                         <ext:store ID="FleetStore" runat="server" idmode="Explicit" ClientID="FleetStore" >
                            <reader>
                                <ext:jsonreader IDProperty="IDENTIFIER">
                                    <fields>
                                        <ext:recordfield Name="IDENTIFIER" Mapping="IDENTIFIER" />                        
                                    </fields>
                                </ext:jsonreader>
                            </reader>
                         </ext:store>         
                    </store>
                    <listeners>
                      <select Fn="selectListener" />
                    </listeners>
                    </ext:multicombo>

                    .....

I am binding the store to a datatable in code behind on the hidden button click but the list remains empty (it works fine if I load it on page load). Any idea? I am using Content instead of Items in outer panel because I have ASP.NET controls inside this outer panel which I can not add if I use Items.

Hi @OSYS_FMS,

Please demonstrate how you bind a data.

Can you see a new bound data in the response?
