我有一个30行的gridview。我想打印3页，每行10行。我试过这段代码。
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowIndex % 10 == 0 && row.RowIndex != 0)
{
row.Attributes["style"] = "page-break-after:always;";
}
}
但是它打印整个页面没有任何分页符。我曾经使用javascript调用打印函数（如下所示）。
function PrintGridData() {
var prtGrid = document.getElementById('<%=GridView1.ClientID %>');
prtGrid.border = 0;
//GridView1.Attributes(style) = "page-break-after:always"
var prtwin = window.open('', 'PrintGridViewData', 'left=100,top=100,width=1000,height=1000,tollbar=0,scrollbars=1,status=0,resizable=1');
prtwin.document.write(prtGrid.outerHTML);
prtwin.document.close();
prtwin.focus();
prtwin.print();
prtwin.close();
}
帮助???

我用ie10和firefox 22测试了page-break-after: always; - 它适用于两者;在Chrome 30中，它不起作用。所以很难说它为什么在firefox 22中不适合你。
如果您的用户群主要是IE和Firefox（就像我们公司一样）。这将有效：
.pagebreak {
page-break-after: always;
}
显然对css分页功能的支持并不理想：
search for chrome issues引导我发出99124 - Printed table content does not respect page-break CSS properties; 2011年10月4日报道，仍然没有受到影响：Confirmed, not reviewed for priority and assignment。印刷似乎并不重要。
添加此css也无济于事：
@media print
{
table tr.pagebreak {page-break-after:always}
}
解决方法可能是将表拆分为多个表 - 对于每个页面。用户点击按钮后，此 demo breaks a single table into n tables 。你也需要这个css hr {page-break-after: always;}。
我更新了javascript以在每个页面之间加入<hr />，甚至强制Chrome添加分页符。
function printTable(){
var tables = createTables(2);
$("#printTables").html(tables);
}
function createTables(rowsPerTable){
var rowsInParentTable = $( "tbody tr" ).toArray();
var subTable = "<table>", subRows=[], sr = 0;
for(i=0; i < rowsInParentTable.length; i++){
subTable += "<tr>" + rowsInParentTable[i].innerHTML + "</tr>";
if( i % rowsPerTable === 0 && (i > rowsPerTable || i +1 > rowsPerTable ){
subTable += "</table> <hr /><table>";
}
}
return subTable;
}
和html
<div>
<table id="sourceTable">
<tbody>
<tr><td>1 Browser</td>
<td>Version</td>
<td>Support for 'page-break-after' </td></tr>
<tr><td>2 Internet Explorer</td>
<td>10</td><td>works for table rows</td></tr>
<tr><td>3 Fire Fox</td><td>22</td>
<td>works for table rows</td></tr>
<tr><td>4 Chrome</td><td>30</td>
<td>does not work</td></tr>
<tr><td>5 Safari</td><td>?</td><td>?</td></tr>
<tr><td>6 Opera</td><td>?</td><td>?</td></tr>
</tbody>
</table>
<button onclick="printTable()">print table</button>
</div>
<div id="printTables">
</div>
我会创建一个单独的aspx页面来处理打印页面。这样你就可以拥有完整的服务器端控制，并且可以使用转发器来创建你需要的html输出。

if (!IsPostBack)
{
var sb = new StringBuilder();
string s;
show();
for (int i = 0; i < GridView1.PageCount; i++)
{
GridView1.FooterRow.Visible = false;
GridView1.PageIndex = i + 1;
sb.Clear();
GridView1.RenderControl(new HtmlTextWriter(new StringWriter(sb)));
s = sb.ToString();
Response.Write(s);
if (i != GridView1.PageCount - 1)
{
Response.Write("<p></p>");
}
show();
}
GridView1.Visible = false;
}
public override void VerifyRenderingInServerForm(Control control)
{
}
I have used this method to solve the case..I have applied paging to the **gridview** and it works!!!
