Lesson 6: Add a ReportViewer control to the application
After you design the child report by using the Report Wizard, your next step is to add a ReportViewer control to the website application. If you're using the ASP.NET Reports Web Site, it adds the ReportViewer control to the default.aspx page.
Add a ReportViewer control to the application
In Solution Explorer, right-click Default.aspx, and then select View Designer.
If default.aspx already has the ReportViewer Control on it, skip to Step 4. Otherwise, From the AJAX Extensions group in the Toolbox window, drag a ScriptManager control to the design surface.
From the Reporting group, drag a ReportViewer control to the design surface below the ScriptManager control.
Open the ReportViewer Tasks window by selecting the arrow in the top right-hand corner of the ReportViewer control.
In the Choose Report box, select the parent report you created.
When you select a report, instances of data sources used in the report are created automatically. Code is generated to instantiate each DataTable (and its DataSet container). An ObjectDataSource control is added to the design surface, corresponding to each data source used in the report. This data source control is configured automatically.
On the Build menu, select Build website.
The report is compiled and any errors such as a syntax error in a report expression appear in the Error List area. Select Error List at the bottom of the Visual Studio window to display the Error List area.
