Hi,

I am trying to pass the Data from C# to Telerik Report. Initially i created a Web Project and I added Telerik Report to the Project. I followed a tutorial to create a Report and assign a Dataset to the Report. Here i will be designing a Report. I need to assign a Data To Report through a Datatable, which need to be populated in Report where we need to Map The Columns. On Page Load i am Trying to do this,

In My Page Load i written by Code as

   Report2 objReport2 = new Report2();
                objReport2.DataSource = GetAllData();
                ReportViewer1.ReportSource = objReport2;
                ReportViewer1.DataBind();
                ReportViewer1.RefreshReport();

From the above code, i am seeing the blank Report wihtout Data.
In Desinger i created a table, But i failed to create  a Mapping between Report And Dataset Column? May i know how do i do this? Or else can any one suggest me a scenario to resolve this?   
Please find the Sample Project Link http://www.mediafire.com/?9hd3apr88j6m17x

Hello Sudhakar,

The code you've provided is not correct and should be modified as follows:

Report2 objReport2 = new Report2();
Telerik.Reporting.Table tableItem = objReport2.Items.Find("table1", true)[0] as Telerik.Reporting.Table;
Telerik.Reporting.ObjectDataSource obds = (Telerik.Reporting.ObjectDataSource)tableItem.DataSource;
obds.DataSource = GetAllData();
obds.DataMember = "Product";
Telerik.Reporting.InstanceReportSource irs = new Telerik.Reporting.InstanceReportSource();
irs.ReportDocument = objReport2;
ReportViewer1.ReportSource = irs;
ReportViewer1.RefreshReport();

Please note a few important things:
  • the Table item is a separate Data Item that has its own data source, so you should find the data item in question and get the DataSource from it.
  • a single data item can be bound to a single data source and a data source can be bound to a single datatable. Since your query returns 3 tables, you should use the DataMember property of the data source component to specify which DataTable to bind to.
  • the ReportSource property of the viewer expects a reportsource type, not report.

In general whenever your data comes from a database server, it is recommended to use the SqlDataSource Component as datasource instead. I have attached your modified working project, you can see Report1 which binds directly via the SqlDataSource component.

All the best,
