Follow Mode

Hi,

I'm using ArcGIS Runtime .net 100.9 version. I'd like to know if there's a way of center constantly the map on the movement of an element. What I'm using now is to when moving the element, make a SetViewpointCenterAsync, but it's not a valid approach since the map's center is changed everytime. Map should stay centered all the time on the element without any visual effect.

Regards

Gonzalo

Hi @JoeHershman,

yes as stated in my comment of January I made multiple tests but none of them was succesful.... Have you tried this functionality with a correct behavior?

Thanks

Did you ever play around with WanderExtent to get it to change how quickly it recenters? Setting to 0 should have it continuously recentering

Hi sandiegomonedero,

we are now using the SetViewpoint method and it has improve the performance of the FollowMode, but now graphics are flashing and sometimes there's a lack on the viewpoint and graphics reposition... Any idea on how to proceed? Our costumer has not accepted still the solution.

This example may help

You could also try the non asyncronous SetViewpoint to remove the lag you may have with the asyncronous one.

Thanks @JoeHershman . I've been testing that functionality with the Code Samples (Show Location History) and it's not working correctle as it recenters late and not with each position update. Apart from that, when panning on the mapview, it sems like the functionality is stopped. Is something wrong on the sample or is it a bug? Will this bugs be fixed?

If yes, how can this be used to assign a graphic to be recentered, because from what I've seen you create the symbol on runtime, but I need to assign this recenter mode to a already created graphic.

The MapView has a LocationDisplay property. LocatonDisplay has AutoPanMode.

mapView.LocationDisplay.AutoPanMode = LocationDisplayAutoPanMode.Recenter;
