I have been working on a Data-Shapes Multiple Input Form but i would like to add realtime feedback for the end user on selected Model Lines (With and SelectModelElements Data UI, see below:
sadly what you wanna achieve is not possible for datashape package because it requires an event listener, and from what i know datashape UI doesnt provide that function.
But there is a workaround whereby, you can pop up another one datashape UI to show the selected model lines and give the user a double confirmation to do what your script is gonna do. thats the best piece of advice i can give you, i think. Open to hearing any feedbacks from other as im also interested in winforms and WPF
