Hi

I'm trying to create a gridview where the rows are grouped together by sort expressions, like the one on this link:

http://aspadvice.com/blogs/joteke/archive/2006/02/11/15130.aspx

However, I'm getting the error:

"The data source "myobjectdatasource" does not support sorting with IEnumerable data. Automatic sorting is only supported with DataView, DataTable, and DataSet"

My controller class has a function which returns a generic List(Of objects). I can't find a method in the DAL which returns a dataset, so how can I convert this List to a DataSet or DataTable so that it will work with the objectdatasource and the gridview, or is there another method I could use to achieve the same end result?

Thanks

Ryan

Thanks Michael. I added new methods to my code to retreive a dataset instead, and it works now. Looks great.

Yes, I'm using the custom List(Of T) for inserts, updates, and deletes, but this particular gridview is display only, based on a result set pulled from another table joined with the data in the articles table, so i just used a SQLHelper rather than CBO.FillCollection. I can now group my gridview columns by any datacolumn and produce summary rows.

I found your tutorials very useful, and i'm getting the hang of it now using the starter kits. Much easier than under .Net 1.1.
