推荐答案

将DataTable手动绑定到报表查看器

删除报表查看器控件上的所有设计器数据绑定
(请确保< DataSources>元素中没有任何内容，如下所示)

To manually bind a DataTable to a report viewer

Remove any designer data bindings you have on the report viewer control
(make sure there''s nothing in the <DataSources> element as shown below)

<LocalReport ReportPath="Report.rdlc">
  <DataSources>
  </DataSources>
</LocalReport>

在您的App_Code文件夹中添加一个新的虚拟数据集(如果有的话，请使用其中一个).在设计器中放置一个表，并添加要使用的数据表中的相同列(我将假设数据集的名称为DataSet1&DataTable的名称为DataTable1)

准备好数据集后，就可以在报表设计器中添加表或其他对象了.将字段从DataSet拖到它上.

在事件或Page_Load
中，这是将DataTable(或DataSet)中的数据绑定到报表的方法 假设您有一个名为dt的已加载数据表

Add a new dummy DataSet in your App_Code folder (or make use of one if you have). Place a table in the designer and add the same columns you have in your datatable you wish to use (I''ll assume the name of the DataSet is DataSet1 & that of DataTable is DataTable1)

Once you have your DataSet ready, you may add a table or other object in your report designer & drag fields from the DataSet onto it.

Here''s how you bind your data in DataTable (or DataSet) to the report - in a event or Page_Load
Assuming you have a loaded DataTable named dt

ReportDataSource rds = new ReportDataSource("DataSet1_DataTable1", dt);
ReportViewer1.LocalReport.DataSources.Add(rds);
ReportViewer1.DataBind();

记住要为其导入名称空间Microsoft.Reporting.WebForms

我有一个演示页面，展示了如何做-如果您需要它，请问我.我将其发送.

Remember to import namespace Microsoft.Reporting.WebForms for it

I have a little demo page showing how to do it - if you need it, ask me. I''ll send it.
