如何在服务器端处理treepanel单击的节点详细信息（id，text，tag或Ext.Net.Node对象）？

Question

我试过下面的代码。

我正在使用该版本https://www.nuget.org/packages/Ext.NET.MVC/3.2.0

TreePanel treePanel = new TreePanel();
treePanel.ID = "TreePanel1";
treePanel.RootVisible = false;
treePanel.DirectEvents.ItemClick.Url = "/Menu/TreePanelClickHandler";
treePanel.DirectEvents.ItemClick.Method = HttpMethod.POST;
treePanel.DirectEvents.ItemClick.ExtraParams.Add(new Parameter("param1", "value1", ParameterMode.Value));
treePanel.DirectEvents.ItemClick.ExtraParams.Add(new Parameter("param2", "value2", ParameterMode.Value));

控制器

public class MenuController : Controller
{
   public ActionResult TreePanelClickHandler(string param1,string param2)
   {
      X.Msg.Alert("server-side:", param1 + "\n" + param2).Show();
      AjaxResult r = new AjaxResult();
      return r;
   }
}

任何想法？

Answer 1

create table so_gibberish.fred1
(
    id int auto_increment primary key,
    what varchar(40) not null
);

insert so_gibberish.fred1 (what) values ('this'),('that');


insert into newdb789.fred1 select * from so_gibberish.fred1;

-- failed, error code 1146: Table 'newdb789.fred1' doesn't exist

create table newdb789.fred1
(
    id int auto_increment primary key,
    what varchar(40) not null
);

insert into newdb789.fred1(id,what) select id,what from so_gibberish.fred1;
insert into newdb789.fred1 (what) values ('a new thing');

select * from newdb789.fred1;

+----+-------------+
| id | what        |
+----+-------------+
|  1 | this        |
|  2 | that        |
|  3 | a new thing |
+----+-------------+

当Ext.Net.Node创建

时

TreePanel treePanel = new TreePanel();
treePanel.ID = "TreePanel1";
treePanel.Border = false;
treePanel.RootVisible = false;

treePanel.DirectEvents.ItemClick.Before = "o.extraParams.param1 = record.data.id; o.extraParams.param2 = record.data.text; o.extraParams.param3 = record.raw['tag'];";
treePanel.DirectEvents.ItemClick.Url = "/Menu/ClickMeHandler";
treePanel.DirectEvents.ItemClick.Method = HttpMethod.POST;

控制器

subNode.CustomAttributes.Add(new ConfigItem("tag", "testdata"));
