        columns: grid.Columns(
     grid.Column(header: "", format:  (item) =>

                    Html.ActionLink("Détails", "Details", new { id = item.id_client }, new { @class = "details" }), style: "actions"),

                    grid.Column(header: "", format: (item) => Html.ActionLink("Supprimer", "Delete", new { id = item.id_client }, new { @class = "supprimer" }), style: "actions"),

                    grid.Column("Nom",canSort: true),
                    grid.Column("Prenom", "Prénom",canSort:true),
        grid.Column("Email")));


                        }

Answer 1

You can try add the list of name columns for your webgrid, for example:

var grid = new WebGrid(canPage:true ,canSort:true, rowsPerPage :4);

grid.Bind(Model,columnNames: new[] { "Nom", "Prenom"}); //adding names of columns

grid.Pager(WebGridPagerModes.NextPrevious);
@grid.GetHtml(...

Sometimes web grid can't understand how bind your model with columns.
