Posted on 2014-02-11

Last Modified: 2016-08-29
When I run the pageload in attached file I get the error "The Select operation is not supported by ObjectDataSource 'ObjectDataSource1' unless the SelectMethod is specified."

Of course I know why I am getting this but is there no way to set this programmatically?

Please guys only reply if you know the answer definitely please do not send me to reams of websites I can do that myself.


Thanks.

Try like below. Looks like you are closing the connection early.

protected void Page_Load(object sender, EventArgs e)
        {
            SqlConnection MySQL = new SqlConnection();
            MySQL.ConnectionString = ConfigurationManager.ConnectionStrings["BConn"].ConnectionString;

            SqlCommand command = new SqlCommand();
            SqlDataReader drReport;
            DataSet dsReport = new ReceiptPDS();
 
           

            try
            {
                MySQL.Open();
               
                command.CommandType = CommandType.Text;
                command.Connection = MySQL;
                command.CommandText = "Select DateNo AS Date, TCode AS Test, Price FROM PTest";
               

                drReport = command.ExecuteReader();
                dsReport.Tables[0].Load(drReport);

               
                ReportViewer1.LocalReport.ReportPath = "ReceiptPRep1.rdlc";

                ReportDataSource rds = new ReportDataSource();
                rds.Name = "ReceiptPDS_ReceiptPDS";
                rds.Value = dsReport.Tables[0];
               
                ReportViewer1.LocalReport.DataSources.Add(rds);


            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
            finally
            {
                if (drReport != Null)
                 {
                            drReport.Close();
                 }


                if (MySQL.State == ConnectionState.Open)
                {
                    MySQL.Close();
                }
            }
        }

Your code works just fine as is, I actually tried it (with modifications for my database). And your code does not have and does not need any ObjectDataSource anyways. Maybe it was added by some wizard when you were playing with it, but the code that you posted creates and binds programmatically everything needed for the report. The only thing that is missing is dataset ReceiptRDS with the table ReceiptPDS inside, and report template ReceiptPRep1.rdlc.

Even if you used UI rather than code, it's probably easier to add not ObjectDataSource but SQLDataSource.

Sorry for timelapse guys.

@apeter i see your point however i still get same error even when I fix this.

@vadimrapp1 I deleted ObjectDataSource but now it complains it still needs a datasaource. Could you please let me have your files so I can compare to my code?

Why you are using data reader and then populating dataset, instead directly get dataset using the command object.

@apeter I am following an example from a book on SSRS in c#. If you have a specific code change suggestion that you have gotten to work please let me have it

@vadimrapp1 I am at a loss as to how to see if your code works, first it seems to be in VS2008 and secondly has no solution file, is it not a web app? I can make changes and convert it etc but really I just want to see it working

Ok, I uploaded new sample at https://filedb.experts-exchange.com/incoming/ee-stuff/8343-vrapp1.rarhttps://filedb.experts-exchange.com/incoming/ee-stuff/8346-website.zip


To try it out:
1. download website.zip and extract to folder
2. open visual studio and open website from file system, point it to the folder from #1
3. open code of the webpage and change connection string to connect to your database
4. run it.

But if you are practicing or trying to learn how this plays together, you in fact can have report without a single line of code.

Create new asp.net webform
add report viewer
from smart tag, select "design new report"
go through the wizard, specify connection and your table, move the fields to the right places in the report (page/group/details)
That's all.
