DevExpress DataGrid's ColumnChooser

Question

I use AutoPopulateColumns system to display my structure on DataGrid. is there any propertie's Attribute to show Property on ColumnChooser window, not on the grid?

Thanks.

Answer 1

Ok, I can't find such default attribute, so I've created my own empty attribute, call it "ShowInColumnChooserAttribute".

Mark all properties, that I don't need on dataGrid, but need on ColumnChooser with this attribute

And in dataGrid's event "ColumnsPopulated" do the next:

        var hiddenList = new List<string>();
        var r = dataTable.ItemsSource.GetType().GetGenericArguments()[0];
        foreach (var prop in r.GetProperties())
            if (prop.GetCustomAttributes(typeof(ShowInColumnChooserAttribute), true).Length > 0)
                hiddenList.Add(prop.Name);
        foreach (var column in ((DevExpress.Xpf.Grid.GridControl)sender).Columns)
                column.Visible = !hiddenList.Contains(column.FieldName);

I think that this is very easy and beautiful solution! Hope this'll help!
