Asp.Net 中Report Service (RDLC)动态绑定数据-学习笔记
Asp.Net 中Report Service (RDLC)动态绑定数据-学习笔记
1）托拽ReportViewer控件到aspx页面，此时，系统会自动添加相关引用，修改Web.config设置；
2）修改ReportViewer属性，添加对报表文件的引用：<LocalReport ReportPath="Report.rdlc"></LocalReport>
页面代码：
1
<form id="form1" runat="server">
2 <div>
3 <rsweb:ReportViewer ID="ReportViewer1" runat="server" Height="703px" Width="845px">
4 <LocalReport ReportPath="Report.rdlc"></LocalReport>
5 </rsweb:ReportViewer>
6 </div>
7 </form>
<form id="form1" runat="server">2
<div>3
<rsweb:ReportViewer ID="ReportViewer1" runat="server" Height="703px" Width="845px">4
<LocalReport ReportPath="Report.rdlc"></LocalReport>5
</rsweb:ReportViewer> 6
</div>7
</form>3）新建数据格式文件（.XSD文件），并在xsd文件中新建一个DataTable
4）新建RDLC报表文件，根据我们的xsd文件格式进行报表设计
5）程序中动态绑定数据（dataSource）和参数（Parameter）
