We want to get flexible component dimension and set new dimension from app UI, So please can we know how to do that.
From above snap we want handle for new value i.e. 25 and set new updated value as per user input.
There is a "Flexible Components" paragraph under the Assembly: Basic Assembly Access chapter of the user guide. I guess that should put you on the right track.
Sorry I can't be more specific but I didn't had the chance to work with flexible components from TK application.
