Is it possible to use datatables as datasource for reportviewer component? Can you provide refference or simple steps how to do that?

Answer 1

Try something like this.

this.reportViewer.LocalReport.DataSources.Clear(); 
DataTable dt = new DataTable(); 
dt = this.inputValuesTableAdapter.GetData();     

Microsoft.Reporting.WinForms.ReportDataSource rprtDTSource = new Microsoft.Reporting.WinForms.ReportDataSource(dt.TableName, dt); 

this.reportViewer.LocalReport.DataSources.Add(rprtDTSource); 
this.reportViewer.RefreshReport();
