Question

i sent XElement to my method to convert it to objects

and it result assigned to DataGrid source( method return 832 object )

but gridview doesn’t show any thing

dgv.DataSource = from objselect in Utility.ListXElementToDeclaration(query)
                        select objselect;

Answer 1

1. objselect should have some properties (not fields)
2. dgv.AutoGenerateColumns should be true, or you should have some columns defined
3. You probably need a List<> : dgv.DataSource = (from .. select objselect).ToList();

And it’s not a bad idea to use a BindingSource as a middleman between dgv and the List.
