Dynamic data source problem in Chart

[Matthew]

Hi all,

I bind a list object as a data source in my report. I created a group and for every 'id' in detail section i want to show two properties in chart. Think that my class is

public class SurveyListGraphicalCompareModel
    {
        public string Question{ get; set; }
        public Guid? QuestionID { get; set; }
        public decimal? avgScore { get; set; }
        public decimal? avgScoreEx { get; set; }
    }

I produce List<SurveyListGraphicalCompareModel> data source from database and bind it to report in my
page's code behind like that :

Reporting.GraphicalComparison rapor = new Reporting.GraphicalComparison();
 myReport.DataSource = myDataSource;
 this.ReportViewer1.Report = myReport;

I grouped data source by QuestionID. And for every QuestionID i want to display Question and a chart(Avg-Sc
ore, AvgScoreEx) in a horizontal series orientation. But i failed and get "There is no or empty series"
error. I could understand how to identify a series regarding to data source field. Could not find any
tutorial explains how to dynamically data bind in telerik reporting chart. The examples i looked up were always on static data source. Could you please show me some examples about that or help me for this specific problem.

Thanks.

Hi Matthew,

Take a look at the following forum threads that should get you started:

• Graph for each group
• Group with chart
