Question

I am using Ext.Net I have a form with a ComboBox which I have just changed to a MultiCombo.

Previously I used “SelectEnquiry.getValues()” to retrieve the selected item and pass it into a parameter used with a Button Direct Event.

How do I get the selected values when using the MultiCombo?

Combo Box Bit

    <ext:MultiCombo runat="server" ID="SelectEnquiry" FieldLabel="Enquiry" AnchorHorizontal="95%" Editable="false" ValueField="Id" DisplayField="ProviderName" TypeAhead="true" Mode="Local" ForceSelection="true" TriggerAction="All" EmptyText="Select Enquiry" ValueNotFoundText="Select Enquiry" ItemSelector="div.list-item" SelectOnFocus="true" AllowBlank="false">

Button form submit bit

 <ext:Button runat="server" ID="ButtonEmailTaskAccept" Text="OK">
        <Listeners>
            <Click Handler="if (PanelUnlinked.isVisible() && !$form.validate( [SelectProject, SelectEnquiry])) return false;">
            </Click>
        </Listeners>
        <DirectEvents>
            <Click Url='<%# Url.Action("CompleteEmailTask") %>' AutoDataBind="true"
            Success="window.$messageBus.publish('task-admin', 'inbox-changed');
            window.$messageBus.publish('task-admin', 'task-changed');
            WindowAssignEmail.close()" Failure="$shell.requestFailedHandler(response, null)"
                Json="true">
                <EventMask ShowMask="true"></EventMask>
                <ExtraParams>
                    <ext:Parameter Name="emailResponseId" Value="<%# Model.EmailResponse.Id %>" Mode="Value"
                        AutoDataBind="true" />
                    <ext:Parameter Name="enquiryId" Value="SelectEnquiry.getValues()" Mode="Raw" />
                    <ext:Parameter Name="documentList" Value="buildSelectionList()" Mode="Raw" />
                </ExtraParams>
            </Click>
        </DirectEvents>
    </ext:Button>

Answer 1

The problem seemed to be that it could not locate the control I was try to get the value from.

So managed to solve it by doing:

#{SelectEnquiry}.getSelectedValues()
