Question

Has anyone got this exception thrown when using the the controls databinding methods??

I have a data structure like this

public class ChartData {    public int Year {get;set;}    public decimal Stat {get;set;} } 

Its collection is

List<ChartData> cData; 

So i bind this object as

chart1.BindXY(cData,'Year',cData,'Stat'); 

I get same exception when using other databinding methods too

Answer 1

What is chart1?
Is that an external charting component?

Open the charting component dll using reflector OR see the docs for appropriate method to use.
