winform下拉框控件叫什么（外网使用winform应用程序）

一直以来winform的listview都只是作为数据输出显示来用, 想要实现数据的双向操作比较难

之前都需要用其他表格类控件实现这个双击编辑文本,双击实现下拉列表框选择文本功能, 而且其中有很大一部分是ocx组件,

那么就需要在客户电脑上regsvr32 注册它, 这样就需要管理员权限, 这样操作并不是很好,

于是考虑着手动改造listview使其满足我的需求.

还好, aardio范例里有个数据视图win.ui.grid的库可供参考, 我就是根据这个库内的实现方法来升级改造的.

下面我在原listview grid基础上增加了, 双击指定列 可直接编辑文本 / 弹出下拉框选择文本 功能.

listviewEX.aardio 库代码如下:

//listview 扩展
import win.ui.ctrl.edit;
import win.ui.ctrl.combobox;
namespace win.ui;
class listviewEx{
    ctor( listview ){
        this = listview; 
        this.fullRow = 1;
        this.gridLines = 1;
        this.columnsEditbox = {};//记录编辑框列号
        this.columnsCombobox = {};//记录下拉框列号和列表值
        //添加下拉框模板
        this.addCtrl(
            combobox = { 
                cls="combobox";font = LOGFONT( h = -19 );left = 0;top = 0;
                right = 50;bottom = 50;autoResize = false ;hide = 1;edge = 1;mode="dropdownlist";
                wndproc = function( hwnd, message, wParam, lParam ){
                    var update;
                    var event = owner.event;

                    if( message == 308 ) {
                        update = true;
                    }
                    if( update ){
                        owner.show(false);
                        var t = this.getItemText(event.iItem,event.iSubItem );
                        if( t!= owner.text ){
                            if( this.onEditChanged ) {
                                    if( false === this.onEditChanged(owner.text, event.iItem, event.iSubItem)) 
                                        return;
                            }
                                
                            this.setItemText( owner.text, event.iItem, event.iSubItem );
                        }
                        
                        if(this.onEditEnd){
                            this.onEditEnd(event.iItem, event.iSubItem);
                        }
                    }
                }  
            }
         );
        //添加编辑框模板
        this.addCtrl(

使用的时候也很简单, 直接指定哪一列是需要文本编辑, 哪一列需要下拉框编辑即可.还可以指定下拉框内容哦
