有关用asp.net+vb打印的问题！！！

具体怎么做啊，我刚学.net
我现在在.aspx.vb中编东西
能再给我具体的讲讲么？？？谢谢~~~~~~~~

smx717616(.Net┷我很菜),谢谢了。我也正找这种实现方法

smx717616(.Net┷我很菜)讲的就是一个控件。
我打印时用的就是这个控件，感觉还行。

这是我找到的一个DataGrid控件通用打印类.但是调试老出问题，我把
加在Public Class WebForm1
Private aa As PrintDataGrid.PrintDataGrid
end sub 里
下面的加在button 事件里
        aa = New PrintDataGrid.PrintDataGrid(DataGrid1)
       aa.setPrintFont() = New System.Drawing.Font("宋体", 12)          '打印文本的字体
        aa.setPrintRecordNumber = 30                                      '每页要打印的记录行数
        aa.Print()但是“PrintDataGrid.PrintDataGrid”总出现语法错误，不知道为什么，哪位高手帮我调调~~~
