ASP模仿asp.net的DataGrid

　　asp.net|datagrid|asp.net|datagrid

自动生成表格，自动完成删除，编辑、填加、分页功能，自定义样式表头样式

代码用两个类来实现

一开始考虑得太多，功能想得太强大，通用性越强，asp类跑起来越慢，做到后来没兴趣，还有很多功能没有完成，如字段类型验证，显示图片、控件等，帖出代码供大这一起学习研究，有兴趣的可以将这些功能加上

示例：

set a = new DataGrid
'a.Connstr="Provider=SQLOLEDB.1;User ID=sa;Password=servser;Initial Catalog=temp_blue;Data Source=server;Connect Timeout=30;Auto Translate=True;Packet Size=4096;"
a.Connstr="Provider=Microsoft.Jet.OLEDB.4.0;"&" Data Source="&server.mappath("test.mdb") '连接ACCSS字符串
a.SQLString="select * from table1" '生成datagrid所显示的记录集的sql语句
a.isAddnew = 1 '是否可以填加新记录
a.Table = "table1" 'datagrid控制的主表
a.UniqueField = "ID" '标志字段，所有记录不重复整型即可
a.PagePosition = "down" '分页显示位置，up上面，down下面 updown上下 ,其它为不显示
a.pagesize = 5 '每页显示记录数
a.Pagenumber = 10 '显示页数

a.BorderColor="#ff0000" '默认为效果图显示

a.BackGround="#00ff00" '默认为效果图显示

a.BorderWidth=1 默认为1

a.
set b1 = new column
b1.Field = "id" '此列所绑定的数据库字段
b1.Title = "标志" '标题
b1.Align = "center" ' 对齐方式
a.AddColumn(b1) '把此列插入到datagrid
set b2 = new column
b2.Field="firstname"
b2.Title="姓"
a.AddColumn(b2)

set b3 = new column
b3.Field = "lastname"
b3.Title = "名"
a.AddColumn(b3)

set b4 = new column
b4.Field = "logintimes"
b4.Title = "登陆次数"
b4.ReadOnly = true '设为只读，不会出现在编辑框中和新增记录中
a.AddColumn(b4)

set b5 = new column
b5.Title="编辑"
b5.Columntype ="edit" '编辑列
b5.EditCommandText = "编辑" '编辑按钮文本
a.AddColumn(b5)

set b6 = new column
b6.align = "center"
b6.Width = 200
b6.Columntype = "delete"
b6.DeleteCommandText = "删除按钮"
b6.Title ="删除"
a.AddColumn(b6)
a.CreateGrid()

set b1 = nothing
set b2 = nothing
set b3 = nothing
set b4 = nothing
set b5 = nothing
set b6 = nothing
