Hello PMac,

Thank you for posting in our forums!

You can handle the XamDataGrid's ContextMenuOpening event and edit the MenuItems from there.

Below, you can see a C# code snippet of how to achieve this.

private void XamDataGrid_ContextMenuOpening(object sender, ContextMenuEventArgs e)
{
    DataRecordPresenter drp = Utilities.GetAncestorFromType((DependencyObject)e.OriginalSource, typeof(DataRecordPresenter), true) as DataRecordPresenter;
    DataRecord dr = drp.Record as DataRecord;
    Cell cell = dr.Cells["Name"];

    if (cell != null)
    {
        XamDataGrid xdg = sender as XamDataGrid;
        MenuItem deleteMenuItem = xdg.ContextMenu.Items[2] as MenuItem;
        deleteMenuItem.IsEnabled = ("Computer" != cell.Value.ToString());
    }
}

If you have any further questions or concerns with this, please let me know and I will be glad to help.

Sincerely,
