Hello,

I'm looking for a recommendation on the best way to create some buttons that zoom in / zoom out the map.  I found this post  (https://community.esri.com/message/590700?commentID=590700#comment-590700?q=zoomasync ) which talks about how to do it with ZoomAsync in the 10.X version of the runtime but I am using 100.2.1 and ZoomAsync does not seem to be there anymore.  Is there a replacement for ZoomAsync or a different recommended way to accomplish this? I was not able to find any examples of this in the provided samples or docs.

Thanks,

Mark

Mark,

The MapView has some methods on it that you could use; try looking into MapView.SetViewpointCenterAsync, or MapView.SetViewpointScaleAsync.

Doc on these methods can be found at: https://developers.arcgis.com/net/latest/wpf/api-reference/html/Methods_T_Esri_ArcGISRuntime_UI_Cont...

A sample code can be found at: https://developers.arcgis.com/net/latest/wpf/api-reference/html/M_Esri_ArcGISRuntime_UI_Controls_Map...

Hope this helps.

Tony
