关于打印dataGridView

Question

我写的程序有好多dataGridView需要实现打印，但我以前一直用的是报表打印，从来没有直接打印过dataGridView。
现在一点思路也没有，请高手指导指导，

    <script language="javascript">

bdhtml=window.document.body.innerHTML;  
sprnstr="<!--startprint-->";  
eprnstr="<!--endprint-->";  
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);  
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));  
window.document.body.innerHTML=prnhtml;  
window.print();  
}
