Guenter Becker Active Member Licensed User Longtime User Nov 10, 2022 #3 Good Morning Erel, it is the code I tried. Anyway I hope I make myself clear In some situation the Developermust or will be able to change the Text and Background (Drawable) Properties by code. To realize it some set/get Subs may be coded to set/change the the Designer (Basae) Properties values. At present I understood that the Designer Text Properties are reflected by the LBL View in the DesignerCreate Sub. But I do not know how to get access to the Drawable Properties. The only one is Background but that is also no way to adress the Properties. The easiest way will be to have all the Properties of the Base acessible via the Base Object but this is not possible at present because Base is an Object and does not have the requested Properties. Therefore my question is still unanswered: How to get access to all of the Properties of the Base especially to the Drawable/Background ones? Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Nov 10, 2022 #4 It doesn't work like this. If you post an irrelevant error message together with irrelevant code then you should expect to an irrelevant answer... Base is a panel. You can get the background with Base.As(Panel).Background. The background can be all kinds of objects. It is not simple to "clone" it. Upvote 0
