首先对我之前的发表的那篇补充一下:当你在你的建立的工程中要用到我做的那个用户控件的话:声明 Protected DataGridPage1 As DataGridPage,前是你拖进来的控件名,后是你定义用户控件。然后在你代码中要用你的控件就写上:
DataGridPage1.SetTarget(MyDataGrid, New BindDataDelegate(AddressOf binddata)) DataGridPage1.SetStyle(10, False)
下划线部分是你自己写的一个绑定之类的涵数。SUB,FUNCTION 等。
以下是我不做成控件时的代码:

WEB代码:

Finally
'???接
CN.Close()
