The Tridion GUI is powered by JavaScript while the backend is powered by .Net and sending a (nice) message from .Net to the GUI has been very challenging – until now. Using SignalR, an open-source product from Microsoft, it is possible to show or ‘echo’ the message from the .Net Event System, Templates or Customer Resolvers and show them in the GUI. Check out the tutorial that Will Price and I wrote published on SDL Tridion World to find out how to implement this yourself. Special thanks to SDL’s Bart Koopman for helping get the article online and embracing the GitHub Gist embed for source code.
