ObjectDataSource Disappearing and Report not displaying table rows as per data

[Rajiv]

I have created a sample project here, please download it and let me know what is the issue?
https://www.dropbox.com/s/98ufwhrgnj19bdw/SampleReportTest.zip

I need help in generating a sample report can you please help?
I create a design report file and assign it a ObjectDataSource where its datasource is a class.

In my code behind, I give a datatable with the same fields as of the class to render on my report, but its just doesn’t display the rows? Any ideas what I might be doing wrong?

See sample project from my dropbox link above. Also, note once I build the dataexplorer shows no fields/properties of the objectDataSource1.

Hi Rajiv,

In the provided demo you use a Table item, which is a data item having its own DataSource property. Thus at run-time you need to get the Table item from the report instance's Items collection and set its data source e.g.:

// Creating and configuring the ObjectDataSource component:
         Telerik.Reporting.ObjectDataSource objectDataSource = new Telerik.Reporting.ObjectDataSource();
         objectDataSource.DataSource = tempdt; // GetData returns a DataTable

         // Creating a new report
         Report1 report = new Report1();

         (report.Items.Find("table1", true)[0] as Telerik.Reporting.Table).DataSource = objectDataSource;

         Telerik.Reporting.InstanceReportSource reportSource = new Telerik.Reporting.InstanceReportSource();
         reportSource.ReportDocument = report;

         reportViewer1.ReportSource = reportSource;
         reportViewer1.RefreshReport();

More information about setting report's data at run-time is available in the Changing the connection string dynamically according to runtime data KB article.


I hope the above information helps you.
