Apply symbology to featureclass added via button addin

DerekSalinas

Good Afternoon Everyone,

So I have a button created and it is adding a feature class to my map via a FileGeodatabaseConnectionPath. As seen below.

 

            // Add this in your OnClick code-behind for the button
            if (MapView.Active?.Map == null) return;
            ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
            {
                // using the community sample dataset
                using (Geodatabase geodatabase = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(@"U:\environmental\envgist.gdb"))))
                {
                    using (FeatureClass addFeatureClass = geodatabase.OpenDataset<FeatureClass>("counties"))
                    {
                        LayerFactory.Instance.CreateFeatureLayer(addFeatureClass, MapView.Active.Map, 0, "Counties");
                    }
                }
            });

 

What information do I need to add to apply symbology from a lyr/lyrx file to this feature class? The layer files are in a folder stored on the same location as the gdb. 

Any help in the right direction is much appreciated.

Thank You,

Good Afternoon Gin!

Thanks so much for getting back to be so quick. That example worked out wonderfully! I did have to make a few edits to the code, as seen below. 

if (MapView.Active?.Map == null) return;
  QueuedTask.Run(() =>
  {            
  // add lyr/lyrx to map
  var featureLayer = (FeatureLayer)LayerFactory.Instance.CreateLayer(new 
                      Uri(@"layerpath"), MapView.Active.Map, 0, "TOC Name");

  CIMDataConnection currentDataConnection = featureLayer.GetDataConnection();
  CIMStandardDataConnection updatedDataConnection = null;
  WorkspaceFactory wf = WorkspaceFactory.FileGDB;

// FileGeodatabaseConnectionPath does not contain a constructor that takes two arguments

     var dbGdbConnection = new FileGeodatabaseConnectionPath(new Uri(@"gdb 
     Path"));

// provide a replace data connection method

     updatedDataConnection = new CIMStandardDataConnection()
     {
       WorkspaceConnectionString = new 
       Geodatabase(dbGdbConnection).GetConnectionString(),
       WorkspaceFactory = wf,
       Dataset = "FeatureClassName",
       DatasetType = esriDatasetType.esriDTFeatureClass
      };

       featureLayer.SetDataConnection(updatedDataConnection);
       featureLayer.ClearDisplayCache();
  });

 

The main correction was that FileGeodatabaseConnectionPath does not need to have a Uri type to be determined as it does not allow for more than one argument, which is the actual connection path. Maybe something different should be used there instead, but this seems to work all the same.

Once again, thank you for your help. It is very much appreciated.
