[CLOSED] Model Binding POSTed combobox values

[peter.campbell]

Hi,

I'm using model binding to automatically map form POST values into my object. This works perfectly, except when comboxes are submitted. They provide an 'xxxxxx_value' key which is the actual ValueField I need to capture. When I bind (using default MVC modelbinder), it doesn't use this _value property; instead (I presume) using the name property I specify, which is a string - and therefore returns 0 in my bound object.

eg:

 <ext:ComboBox ID="cboActionFunction" runat="server" FieldLabel="Function" LabelAlign="Right"
                            StoreID="storeActionFunctions" DisplayField="ActionFunctionTitle" ValueField="Id"
                            DataIndex="ActionFunctionId" AllowBlank="false" X="5" Y="5" Width="200" ForceSelection="true"
                            SelectOnFocus="true" Name="ActionFunctionId" EmptyText="Set function"
                            ListWidth="150" Mode="Local">

Controller:

 public ActionResult SaveAction(Models.Action act, int? hitlistId, int? actionId) {
....
}

The act object looks great, except combo values equal 0, as the _value property is not picked up, the DisplayField part is instead:

        ActionForId    0    int
        ActionFunctionId    0    int
        ActionStatusId    0    int
        ActionSubject    "A test subject"    string
        ActionTypeId    0    int

Apologies if this is more my misunderstanding of the MVC function; I'm not sure if it's an ext.net quirk or not.

Hi,

Please clarify do you use Ext.NET v2?

Ah! I'm sorry, I didn't meant to post in 2x forums. I'm still using 1.3. Sorry.

I've came across a workaround (perhaps not a workaround, maybe ext.net is doing it correctly?) if anyone is interested.

HiddenName="ActionFunctionId" HiddenValue="this.getValue()"

This submits the value I want with just the name ActionFunctionId, which the model expects to be an int and so it binds it correctly.

Yes, you should set up a respective HiddenName.

Also, I think setting

HiddenValue="this.getValue()"

is not required.

Confirmed. The HiddenValue part is not needed. Can you clarify, I have in this same formpanel a TopBar with some comboboxes. These don't appear to be submitted at all, is this the standard behaviour due to being in a toolbar/topBar?

[Daniil]

A field is submitted automatically when it's within a <form> HTML element.

I guess you use

FormPanel1.getForm().submit()

and there is no main

<form runat="server">

on your page.

In this case, FormPanel creates its own <form> HTML element and its TopBar is not within that <form>, so, TopBar fields are not submitted. Only FormPanel Items are submitted in this case.

Hope this helps.
