使用vb.net 对 Windows Form 按列排序 ListView 项目使用 Windows Form 按列排序 ListView 项目摘要：说明如何根据所单击的列在 Microsoft .NET 中的 ListView 控件提供项目排序。简介ListView 控件是显示文件系统信息和显示 XML 或数据库数据的非常好的方式。ListView 控件通常用于显示表示项目以及项目文本的图形图标。此外，ListView 控件还可以用于显示有关子项目中项目的其他阅读详情

VB.NET中ListView加载数据和排序功能的实现

        平时我们在VB.NET中开发数据库相关的程序都会用到DataGrid来显示数据，它的使用相对简单，也有排序的功能，基本能满一般的要求。但有时它并不能满足项目的功能需求，这时我们就想到了用ListView,虽然它的功能正是我们所要的，必竞它不是一个数据库的控件，不能像DataGrid那样通过简单的设置就可以显示数据，同时也没有排序的功能，这些就要我们自已用程序代码来实现了。前些天在开发一个项目时就写了一段使用ListView显示数据并实现排序的代码，简单地说一下它的实现原理：显示数据是通过循环读取数据记录，用ListView的Add方法将数据添加到ListView中；排序的功能是通过ListView列的点击事件来得到要排序的字段，再使用ORDER BY关键字组合SQL重新加载数据来实现排序的。欢迎使用VB.NTE的朋友一起交流，我的EMAIL是ztqas@126.com。

    以下是程序所使用的数据库及控件的设置信息：

数据库名：Northwind(SQL SERVER 2000中自带的,如果没有此数据库请先建立)
表名：Products(如果没有这个表，请使用后面附带的SQL语句建立)

窗体名：frmListViewDb

所用控件

Label 1个
属性：Text=ProductName:

-----------------------------------------------------

TextBox 1个
属性：Name=txtProductName

-----------------------------------------------------

Button 5个
(1) 属性：Name=btnFilter、Text=过滤
(2) 属性：Name=btnShowAll、Text=全部
(3) 属性：Name=btnSelAll、Text=全选
(4) 属性：Name=btnCancelSelAll、Text=取消全选
(5) 属性：Name=btnInsteadSel、Text=反选
(5) 属性：Name=btnInfo、Text=查看

ListView 1个
属性：Name=ListViewDb、View=Details、Sorting=None、GridLines=True，FullRowSelect=True，CheckBoxs=True，Size=856,416、Columns添加10个列，Width=150,Text分别为:ProductID,ProductName,SupplierID,CategoryID,QuantityPerUnit,UnitPrice,UnitsInStock,UnitsOnOrder,ReorderLevel,Discontinued
