How to use dataset of .rdl file in web application ( after converting it to .rdlc visual studio 2008 C# and SSRS 2008 R2


I have a situation where I need to use a report which was created initially in SSRS 2008 R2 and has .rdl extension. Now, I want to use this report on (C#) page.
I have added this report in web application package and changed it's extension to .rdlc and droped reportviewer control on design area and assigned imported .rdlc file to it.
Can you please tell me how to use the existing datasets of the report file. As I could not find any option to use the data source already present in the report.
In the meanwhile if go to report's code in xml view I can see all sql statements which are being used in the dataset!!!!!!!!!!

Your comments and suggestions are highly appreciated.

Rdl and Rdlc are used the same way. There is nothing to chnce in the dataset.
I do not know if this will help you using  but this is the kind of code we use on the web site side to view a rdl report in a PDF format. Can be used in 2005 or 2008

     Try this.But you donot need to do step 1 and Step 2 because you have already included file in project.
You also need to change names in this code
           <LocalReport ReportPath="Report.rdlc">
                    <rsweb:ReportDataSource DataSourceId="ObjectDataSource1" Name="DataSet1" />
        <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData"
