Public Class TabDataModel

    <Tab>
    <Icon(GetType(Resources), NameOf(Resources.OffsetImage))>
    Public Class TabControl1
        Public Property Field1 As String
    End Class

    Public Property Tab1 As TabControl1

End Class

using CodeStack.SwEx.Common.Attributes;

using CodeStack.SwEx.Properties;

public class TabDataModel
{
    [Tab]
    [Icon(typeof(Resources), nameof(Resources.OffsetImage))]
    public class TabControl1
    {
        public string Field1 { get; set; }
    }

    public TabControl1 Tab1 { get; set; }

}

Tab with nested groups

Controls can be added directly to tabs or can reside in the nested groups:

Public Class TabControl2
    Public Class Group1
        Public Property Field2 As Integer
    End Class

    Public Property Group As Group1
    Public Property Field3 As Boolean
End Class

<Tab>
Public Property Tab2 As TabControl2

public class TabControl2
{
    public class Group1
    {
        public int Field2 { get; set; }
    }

    public Group1 Group { get; set; }
    public bool Field3 { get; set; }
}

[Tab]
public TabControl2 Tab2 { get; set; }
