title: how to use rdl/rdlc in my asp.net project to generate a report?
body: <p>I have a web application which will use MS ReportViewer. I have another team create a rdl file for me. I renamed the rdl to rdlc and added to my project. And I created a DataSet1.xsd to get the data needed by this rdlc. In my aspx page, I added a ReportViewer control, and set its report property to the rdlc file.</p>
  
  <p>My questions are:</p>
  
  <p>(1) Is it possible to edit the rdl/rdlc in vs2008? When I open it, it is opened as a xml file.</p>
  
  <p>(2) how do I assign the dataset1 to the data source property of the ReportViewer control? When I right click the reportviewer, select the choose data sources, the dataset1 was not listed. Do I have to do this in the code behind?</p>
  
  <p>(3) I got following error The report definition is not valid.  Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition' which cannot be upgraded.</p>
