Hi, is it possible to have popups for a MapImageLayer ? I try with IdentifyTask but it didn't work and instead of FeatureLayer, MapImageLayer seems to not work directly with PopupTemplate. Am I right ? Thanks for your help,
You can open a popup from any map click event and then populate the content with the identifyTask results. See the nice examples here: Get started with popups | ArcGIS API for JavaScript 4.0
