@Html.DevExpress().GridView(settings => {

    settings.SettingsCustomizationDialog.Enabled = true;
    ...
    settings.Columns.Add(c => {
        c.FieldName = "ProductName";

    });

        c.FieldName = "CategoryID";
        c.Caption = "Category Name";
        c.SortIndex = 0;
        c.SortOrder = DevExpress.Data.ColumnSortOrder.Ascending;
        c.AdaptivePriority = 1;
        c.Settings.AllowHeaderFilter = DefaultBoolean.True;
        c.Settings.AllowAutoFilter = DefaultBoolean.False;
        c.Settings.SortMode = DevExpress.XtraGrid.ColumnSortMode.DisplayText;
        c.SettingsHeaderFilter.Mode = GridHeaderFilterMode.CheckedList;
        c.EditorProperties().ComboBox(cb => {
            cb.DataSource = NorthwindDataProvider.GetCategories();
            cb.TextField = "CategoryName";
            cb.ValueField = "CategoryID";
            cb.ValueType = typeof(int);
        });
