Grasshopper Visual Studio C# Slider Scripting

Hi all! I have been using Rhino and Grasshopper for a while now so I decided to jump into visual studio in order to edit Grasshopper open source projects or create my own components. I have been using Grasshopper in order to control industrial robots lately and I came across Taco ABB. This Grasshopper plugin sports an interesting feature that consist in a slider (Please find image below) that overlays the Rhino viewport while controlling the script even when the Grasshopper canvas is minimised.

I am trying to script a component that achieves this and can be attached to a Grasshopper slider. I have been going through David’s Grasshopper documentation specially the section based on Grasshopper GUI but I could not find what I am looking for. Would you have any suggestions or does anybody know any documentation or source that I could use as a reference? I just need someone to point me towards the right direction :slight_smile:

Thank you very much in advance!
