There is a sample that shows how to dynamically join feature classes or tables: https://github.com/Esri/arcgis-pro-sdk-community-samples/tree/master/Geodatabase/DynamicJoins ... View more

We have a 'migration' write-up here:  https://github.com/esri/arcgis-pro-sdk/wiki/ProConcepts-2.0-Migration-Guide Some of the API changes are documented here: https://github.com/esri/arcgis-pro-sdk/wiki/ProSnippets-Migrating-to-2.0 ... View more

Here is a snippet that explains how to get the path: QueuedTask.Run(() =>   {          using (Geodatabase defaultGeodatabase = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(Project.Current.DefaultGeodatabasePath))))          {            FileGeodatabaseConnectionPath connectionPath = (FileGeodatabaseConnectionPath)defaultGeodatabase.GetConnector();            MessageBox.Show($@"Path: {connectionPath.Path}");          }   });‍‍‍‍‍‍‍‍ You can paste this into the OnClick of a button Add-in to test it out. Hope this helps, Wolf ... View more

Hi Fayu,  You can use this code snippet:  return QueuedTask.Run(() => {   var activeMapView = MapView.Active;   MapPoint zoomToPnt = MapPointBuilder.CreateMapPoint(coord.Longitude, coord.Latitude, SpatialReferences.WGS84);   var projectedXY = GeometryEngine.Instance.Project (zoomToPnt, activeMapView.Map.SpatialReference) as MapPoint; });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ There are multiple samples among the community samples that use projection, just search for "Instance.Project" on the community samples GitHub repo for a list of usages. ...

I usually use this snippet of code knowing that through a selection I get a dictionary with the MapMember as key and a list of object ids as the value for each MapMember.  I am using a single mapmember and the corresponding objectId list as input for my sample method below (I am using similar code but this snippet is only pseudo code):     // this in only pseudo code     // call from MCT     public RowCursor GetRowCursor(MapMember mapMember, List<long> objectIds)     {       var basicFeatLayer = mapMember as BasicFeatureLayer;       if (basicFeatLayer == null) return null;       // Create a query filter to fetch the appropriate rows for this mapmember       QueryFilter queryFilter = new QueryFilter()       {         ObjectIDs = objectIds       };       return basicFeatLayer.Search(queryFilter);     }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Hi Luke,  You can look at this sample: OverlayExamples on how to construct line symbology and a 'graphic' object, and you can then use AddOverlayAsync to add the line to your MapView.   Hope this helps. Wolf ... View more

Your snippet looks correct, see here.  The error message unfortunately is not very descriptive as to the cause.  So I would look at the input parameters, especially the path: sPrjDB + "\\Map\\Map.gdb\\Pipe" I would make sure that this path matches the path (and the feature class name) of the manually added layer.  You can find the path by going to the content Dockpane, right-click on the feature layer, select properties, and then source.   ...

Hi M,  I think that your Camera is not properly initialized.  A Camera requires more than just X and Y.  Try to initialize your camera like this  var newPosition = MapView.Active.Camera;‍ ... View more

Hi Sree,  You can take a look at this sample and see if it has what you need: AddInInfoManager It displays version information about add-ins - the 'Version' string is probably what you are looking for: ... View more

Hi Chao,  I am not sure if you are looking for the actual 'datasource' of the Layer.  If so: Layer inherits MapMember and you can use MapMember properties and methods to gain access to CIMDataConnection  Once you have the CIMDataConnection you have to check what type of specific connection you are dealing with (i.e. CIMStandardDataConnection ) as shown this this Button 'OnClick' sample snippet: protected override void OnClick() {   // Arbitrarily, pick the first feature layer - just assuming there is one!   var layer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().ToList()[0];   QueuedTask.Run(() =>   {     CIMDataConnection currentDataConnection = layer.GetDataConnection();     // check the specific type:     if (currentDataConnection is CIMStandardDataConnection)     {       var standardDC = currentDataConnection as CIMStandardDataConnection;     MessageBox.Show($@"WorkspaceConnectionString: {standardDC.WorkspaceConnectionString} Dataset: {standardDC.Dataset} DatasetType: {standardDC.DatasetType}");     }           }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ When I run this on my map (which geodatabase layers on the top), I get this output: with this Map: ...

If the API doesn't expose a method or property for your needs you can usually try the underlying 'Cartographic Information Model' (CIM) for that class.  So specifically for the Map class you can find a BackgroundColor property in the corresponding CIMMap class.  This code snippet will work for you: if (MapView.Active?.Map == null) return; QueuedTask.Run(() =>    {        var cimMap = MapView.Active.Map.GetDefinition();        cimMap.BackgroundColor = CIMColor.CreateRGBColor(0, 0, 255, 138);        MapView.Active.Map.SetDefinition(cimMap);    });‍‍‍‍‍‍‍ Hope this helps. ...
