The method 'OrderBy' must be called before the method 'Skip' Exception

Question

I was trying to implement the jQgrid using MvcjQgrid and i got this exception.

System.NotSupportedException was unhandled by user code         


        

Answer 1

I had the same type of problem after sorting using some code from Adam Anderson that accepted a generic sort string in OrderBy.

After getting this excpetion, i did lots of research and found that very clever fix:

var query = SelectOrders(companyNo, sortExpression);

return Queryable.Skip(query, iStartRow).Take(iPageSize).ToList();

Hope that helps !
