I changed your app. I set AutoGenerateFields to True and HeaderPrefixAreaDisplayMode="FieldChooserButton". City in Person class has attrb Browsable to False so when I first launch app City is not in grid (as it shouldn't) but open field chooser city is there to be shown.

HI,

 Add this xaml to your project:

 <igDP:Field Name="City">

 <igDP:Field.Settings>

 <igDP:FieldSettings AllowHiding="Never"/>

      </igDP:Field.Settings>

  </igDP:Field>

I know that from the thread I mentioned on the OP. I was hoping for a solution more dynamic then hard code in every grid and every field. 

See my classes about 50 all have an Id property (and other properties) which the end user should not see nor should they care, so putting the Browsable attrib was supposed to not expose the property to end user at all (at least in my mind) which is a good solution one place to change and property is still public so outside classes can use property. Also I like the grids to autogenerate fields that way all changes happen in the business layer and the presentation layer just exposes elements it should.

Only solution I can think of now is create a function using reflection to set AllowHiding to Never if Browsable = false. that will require me to make sure every grid is run through that function.

I'll post what I come up with.

Here is what I came up with quickly. Note I programmed this to work with my classes. For example all my grids dataSources inherts a class which inherts BindingList<T>.

/// <summary>
/// Sets AllowHiding = "Never" to properties that have the Browsable attribute set to false
/// </summary>
/// <param name="grid"></param>
public static void SetupAllowHiding(XamDataGrid grid)
{
if (grid == null)
throw new ArgumentNullException("grid", "Parameter grid must not be null");
if (grid.DataSource == null)
throw new ArgumentNullException("grid.DataSource", "DataSource must be assigned");

object o = grid.DataSource;
Type t = o.GetType().BaseType.GetGenericArguments()[0]; //Datasource usally derives from dbObjBaseCollection<T>. Get T the generic Argument.
Field field;

foreach (PropertyInfo pi in t.GetProperties(BindingFlags.Instance | BindingFlags.Public))
{
field = null;

try
{
field = grid.FieldLayouts[0].Fields[pi.Name];
}
catch (Exception)
{
//throw;
}

if (field != null)
{
System.ComponentModel.BrowsableAttribute[] attrbs = pi.GetCustomAttributes(typeof(System.ComponentModel.BrowsableAttribute), true) as System.ComponentModel.BrowsableAttribute[];
if (attrbs != null && attrbs.Length > 0)
{
if (!attrbs[0].Browsable)
field.Settings.AllowHiding = AllowFieldHiding.Never;
else
field.Settings.AllowHiding = AllowFieldHiding.Default;
}
}
}

}
