Thanks for your reply.
I want to achieve is hide all the fields and after to see what they want. To view the field I want to use this code:

private void xdgBase_Initialized(object sender, EventArgs e)
        {
           
            XamDataGrid xdg = sender as XamDataGrid;
            try
            {

Field fprova = new Field();
                fprova.Name = "IdLogBook";
                fprova.FixedLocation = FixedFieldLocation.FixedToNearEdge;
                FieldLayout flMy = xdg.DefaultFieldLayout;
                flMy.Fields.Add(fprova);
                FieldLayoutCollection fcoll = xdg.FieldLayouts;

how do I hide them all?
Sorry for not correct English.

Perfect. Resolved:
xdg.ShowFieldChooser ();

Thank you very much.

Hi,

If you want ot hide all Fields, what you have dones is your best option, since the XamDataGrid does not expose a proeprty/setting that will hide all its FIelds.

Let me know if you requir any furhter assistance on the matter.

Regads Petar.

I run to hide in this way:

 private void xdgBase_Loaded(object sender, RoutedEventArgs e)
        {
           foreach (Field colB in xdgBase.FieldLayouts[0].Fields)
            {
                colB.Visibility = System.Windows.Visibility.Collapsed;
            }
        }

and if you want to do? In WinForm there was an option on the grid.

Thanks
