Hi
Thanks for your input - I often come across this problem and ask on the forum, sometimes an expected property is available but deeper down into the class (i.e. visible property CustomListView1.AsView.Visible = False) or not there at all.
I know nothing of the work behind the Designer but I do suggest that there is some more formal documentation for custom views be generated with a breakdown of the properties and methods available. Most of the posts on the formal regarding custom views are informative in regards to usage but can take a lot of searching to find any detail.
Perhaps this information can be extracted from the source code for the class, I am no B4X expert but I have been programming (In various languages) since about 1980 so I can usually find my way around most. I always try to contribute to the forum but unable to help as the questions are either outside my realm of B4X experience or an B4X expert/experience member has beat me to it!
That said - I volunteer to contribute to such a document it would be my way of contributing to B4X - what do you suggest to get started.
Kind regard
Dave
