C# 如何在打印某些行后在DataGrid中添加分页符

我有一个显示作业列表的DataGrid。当我打印此列表时，如果它转到另一页，则某些行会被截断。我想在15行之后加一个分页符。因此，一旦DataGrid转到第15行，它将转到下一页进行打印

 <asp:DataGrid  CssClass="tblResults" runat="server" ID="dgDetails" AutoGenerateColumns="false">
                                <HeaderStyle CssClass="tblResultsHeader" />
                                <AlternatingItemStyle BackColor="#EEEEEE" />
                                <Columns>
                                    <asp:TemplateColumn HeaderText="Job">

但是分页符放在哪里？

您可以检查页面索引并将行样式设置为“之后分页符”，它将帮助您在打印某些记录后分页符

DataSet dsTable = null;
            dsTable = DataUtils.GetTableProperties(Company.Current.CompanyID, "InvoicePrint" + q.Job.JobScreen);
            if (dsTable.Tables[0].Rows.Count == 0)
            {
                dsTable = DataUtils.GetTableProperties(Company.Current.CompanyID, "InvoicePrint");
            }
            if (dsTable.Tables[0].Rows.Count > 0)

希望有帮助

您可以检查页面索引并将行样式设置为“打印后分页符”，这将帮助您在打印某些记录后分页符
