第一次接触Ext.Net控件,想实现以上功能,但是我试了几天都不行,求高手指点下

功能如下:

问题项是根据问题类型来加载数据的

 

部分代码:

        //-------
                    Html.X().ComboBox().ID("CbType").Name("CbType").FieldLabel("问题类型").Editable(false).LabelWidth(60).Items(
                    new ListItem { Value = "0", Text = "内部" },
                    new ListItem { Value = "1", Text = "外部" }
                    )
                    .SelectedItems(Html.X().ListItem().Value("0").Text("内部"))
                    .Listeners(l => l.Select.Handler = "#{HidType}.setValue(this.getValue());Ext.getCmp('TreePanel1').setRootNode()"),
                    Html.X().Hidden().Name("Type").ID("HidType").Value("0"),
        //-------
                    Html.X().DropDownField().Name("Level").ID("CBLevel").FieldLabel("问题项").LabelAlign(LabelAlign.Left).LabelWidth(60).AllowBlank(false).Editable(false).Mode(DropDownMode.ValueText).EmptyText("请选择...")
                    .Component(c =>
                        c.Add(Html.X().TreePanel().ID("TreePanel1").Shadow(false).UseArrows(true).MaxHeight(250).MinHeight(50).Width(500)
                                .AutoScroll(true).Animate(false).RootVisible(false).Header(false).Root(new Node { NodeID = "-", Text = "Root" })
                                .Store(
                                    Html.X().TreeStore().ID("TreeStore1")
                                    .Root(new Node
                                            {
                                                NodeID = "-",
                                                Text = "Root"
                                            })
                                    .Proxy(new AjaxProxy
                                            {
                                                API = { Read = Url.Action("GetLevel") },
                                                ActionMethods = { Read = HttpMethod.GET }
                                            })
                                   .Parameters(ps => ps.Add(new StoreParameter("type", "0")))
                                )
                                .Listeners(l =>
                                {
                                    l.ItemClick.Handler = "if(record.childNodes.length>0){Ext.Msg.alert('错误','请选择子节点');}else{this.dropDownField.setValue(record.data.id,record.data.text,true);}";
                                })
                              )

自己换种方式实现了,数据库设计成3层即可
