How could I get the value in code behind and show the text in dropdownlist?

[Dalen]

Hi,everyone.
I want to show the text in the dropdownlist and get the value which was selected in the code behind.
I write the code like this,but it doesn't work.
EXT.NET 2.5.2

@model Sys.Sys_Organization
 @(X.FormPanel()
        .ID("PanelList")
        .Frame(true)
        .AutoScroll(true).JsonSubmit(true)
        .BodyPadding(10)
        .Layout(LayoutType.Fit)
        .FieldDefaults(fd => { fd.LabelWidth = 110; fd.LabelStyle = "color:green;padding-left:4px;"; })
        .Items(
            X.Container()
                .Layout(LayoutType.HBox)
                .Items(
                    X.FieldSet()
                        .Flex(1)
                        .Title("Information")
                        .Layout(LayoutType.Anchor)
                        .DefaultAnchor("100%").MarginSpec("0 0 10")
                        .Defaults(X.Parameter().Name("HideEmptyLabel").Value("false").Mode(ParameterMode.Raw))
                        .Items(
                            
                            X.DropDownFieldFor(model => model.ParentId,true)
                                    .Text(Model.ParentOrg.FullName)
                                    .FieldLabel("parentTree")
                                    .EmptyText("--- select ---")
                                    .Editable(false)
                                    .Mode(DropDownMode.ValueText)
                                    .TriggerIcon(TriggerIcon.SimpleArrowDown)
                                        .Component(treePanel => 
                                            treePanel.Add(Html.X().TreePanel()
                                                .Height(300)
                                                .Width(500)
                                                .MinWidth(500)
                                                .RootVisible(false)
                                                .SelectionModel(selectionmodel => selectionmodel.Add(Html.X().TreeSelectionModel().Mode(SelectionMode.Single)))
                                               
                                                .Store(
                                                        Html.X().TreeStore()
                                                            .Proxy(
                                                                Html.X().AjaxProxy()
                                                                    .Url(Url.Action("GetNodes"))
                                                            )
                                                            .Root(
                                                                Html.X().Node().NodeID("Root")
                                                            )                    
                                                    )
                                                    .Listeners(l => {
                                                        l.ItemClick.Handler = @"this.dropDownField.setValue(record.data.id, record.data.text, true);";
                                                            l.AfterRender.Handler = "this.getRootNode().expand(true);";
                                                            l.AfterRender.Delay = 50;
                                                        })
                                                )          
                                            
                                            )
                          
                           
                            ) 
                   
                     )
                 )
        
        .Buttons(
            X.Button()
                .ID("Button1")
                .Text("Save")
                .Icon(Icon.Disk)
                .DirectEvents(de =>
                    {
                        de.Click.Method = HttpMethod.POST;
                        de.Click.Url = Url.Action("Save");
                        de.Click.Success = "saveHandler('EditWindow','PanelList')";
                    }),
            X.Button()
                .Text("Cancle")
                .Icon(Icon.Cancel) 
                .Handler("parent.Ext.getCmp('EditWindow').close()")
        )
    )

controller:
 public ActionResult Save(Sys_Organization entity)
        {
            ServiceFactory.Instance.Get<Sys_OrganizationService>(Sys_Organization).Save(entity);
            return this.Direct();
        }

I try like this :
1、 X.DropDownFieldFor(model => model.ParentId,true)
.Text(Model.ParentOrg.FullName)
In the entity,I can't get the "ParentId" value

2、 X.DropDownFieldFor(model => model.ParentOrg.FullName,true)
In the entity,I can't get the "ParentId" value ，but I can get "ParentOrg.FullName" value

I want to get the "ParentId" value in code behind,and show "ParentOrg.FullName" text in dropdownlist.
How could I do?

Hi @Dalen,

Welcome to the Ext.NET forums!

I think you might need to implement a ModelBinder. Here is some information about that.

Thank you @Daniil
The example you provided make me confused,I try like that but it doesn't work.
I have another way to solve it
I put a hiddenvalue and bind it to "ParentId", the dropdownlist is still bind "ParentOrg.FullName"
when I click the treepanel's item and set the value to it,just like this:

 X.HiddenFor(model=>model.ParentId).ID("hideParentID"),
X.DropDownFieldFor(model => model.ParentOrg.FullName,true)
 . ....
  .Listeners(l => {
      l.ItemClick.Handler = @"getValues(this,record);";
  })

 function getValues(_this,record)
        {
            var Id = Ext.getCmp("hideParentID");
            _this.dropDownField.setValue(record.data.id, record.data.text, true);
            Id.setValue(record.data.id);
        }

If it can bind smartly in the code behind,it will be better..
