Thanks for the feedback, the percentage isn't necessary, a waiting gif will do just fine, any samples or links you could provide me with?

EG showing a message saying loading and a gif. So you could create a behavior that did that and attach it to the dropdown. The thing is if you want something that gives an actual percentage you will need to be able to provide that somehow and use the workerthread approach. regards Nino Kjetil Paulsen wrote: > Hi > > Is there an easy way to show the user that things are loading in the > background when using ajax calls to populate e.g the palette component > based on a selection in a dropdown?
