My organization is working on a new version of our software using ArcGIS Engine. Previous versions of the software (running on ArcGIS Engine 9.3) displayed MapTips fine as long as they were enabled in the mxd. Our new version running on ArcGIS Engine 10 doesn't display MapTips (and they are fine in the mxd).

Is there any code or setting to enable MapTips, or any known reasons that would cause them to not display in an ArcGIS Engine 10 application? I have already discovered that layers within a Basemap layer won't display MapTips, so that is not the cause. Thank you for any advice.


We tried what iterationx suggested, but the MapTips wouldn't display regardless of the state of that flag. The suggestion brenth made was what we needed:

mapControl.ShowMapTips = true;

Is the ShowMapTips property on your map control set to True? My tips are still going and there is no code required other than that property. –  brenth Dec 12 '11 at 21:06
Thank you! That is exactly what we needed. You should post this as an answer so I can accept it. –  Tanner Dec 15 '11 at 21:41

IFeatureLayer thisFeatureLayer = thisLayer as IFeatureLayer;

An anonymous user notes, "This will programmatically set MapTips to display, but in the case described, the MapTips don't display regardless of the state of this flag." –  whuber Dec 15 '11 at 19:15
