I am trying to implement the Demo Code given at :  http://demos.telerik.com/aspnet-ajax/htmlchart/examples/drilldownchart/defaultcs.aspx
I am using same Column names in my database.
It only works for "years" but when i clicked on "2004" or any other year it gives following Error. 

An exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll but was not handled in user code

Additional information: Index was out of range. Must be non-negative and less than the size of the collection.

This error occurs at  the code line :- 

 SqlDataSource2.SelectParameters[0].DefaultValue = Year.ToString();


I am really confused about this. Please help me out in this. 

Looking forward for a quick response. 
Thank you.

Hi,

This issue is not directly related to the RadHtmlChart control but the select parameter of the SqlDataSource. As long as the right data source is passed to the chart it is supposed to render it properly.

You can make a test by replacing the RadHtmlChart with an ASP control (e.g. GridView). If the issue is still reproducible then it is not related to the chart control and possible cause must be searched somewhere else (e.g., in the select parameter of the SqlDataSource).
