Unfortunately, I can not create it in design mode because the tables and their fields are defined in DB, so in design time I do not know which table and fields will be displayed by the Grid View. I created a sample Class: private Panel doc Panel = new Panel(); private Grid View detail GV = new Grid View(); private Sql Data Source sql Detail DS = new Sql Data Source(); public Label mess Lbl = new Label(); private string connection String = "Data Source=xxxx; Initial Catalog=intranet; Integrated Security=True"; private List My problem is that the Grid View is generated sucessfully but I can not update the modified fields. private Grid View load Dynamic Grid(Grid View Grd Dynamic, Sql Data Source sql DS) { Grd Dynamic.

I think the first must be the command field, 2nd and 3rd are "ID" and "elso_detailed_mezo".
