Is it just a fact of changing the method name to get the code to add a new map frame to work? For instance, when I had that same code snippet (starting at "//Build Envelope Geometry for Main Map Frame") without the code starting at " protected override async void OnClick()", it worked. When I added the "//Build Envelope Geometry for Main Map Frame"  code above it now it doesn't work. One difference is that it was under the method "protected override async void OnClick()", but now since I added the " private Task<Envelope> SelectStateAsync(Map m)" method, I had to create a new method to place it within, below the " private Task<Envelope> SelectStateAsync(Map m)" method. Thats where I am having a problem. How do I add code after that method? ... View more

I am new to coding, and have used the above code in an ArcGIS Pro button. However, I cannot seem to get any code to work after zooming to the states layer in the private Task<Envelope> SelectStateAsync(Map m) method. For example, if I want to create a new map frame and add it to the layout after that, why won't the code below work? Anything starting at the " public void BuildEnvelopeGeometry()" won't work. protected override async void OnClick() { { Map m = MapView.Active.Map; if (m != null) { var env = await SelectStateAsync(m); if (env != null) await MapView.Active.ZoomToAsync(env); } } } private Task<Envelope> SelectStateAsync(Map m) { return QueuedTask.Run<Envelope>(() => { Envelope selectionEnvelope = null; FeatureLayer fl1 = m.FindLayers("ProjectArea1").FirstOrDefault() as FeatureLayer; if (fl1 == null) return selectionEnvelope; QueryFilter queryFilter = new QueryFilter(); using (ArcGIS.Core.Data.RowCursor rowCursor = fl1.Search(queryFilter = null)) { //Grab the first record (and hopefully only record) while (rowCursor.MoveNext()) { //Grab the features geometry Feature feature1 = rowCursor.Current as Feature; Geometry geo = feature1.GetShape().Clone(); //Set up a spatial query var spatialQuery = new SpatialQueryFilter() { FilterGeometry = geo, SpatialRelationship = SpatialRelationship.Intersects }; //Reference county layer and apply spatial query FeatureLayer fl2 = m.FindLayers("States").FirstOrDefault() as FeatureLayer; if (fl2 != null) { // this selects the feature(s) in fl2 var selection = fl2.Select(spatialQuery); // this get the envelope using (RowCursor rowCursor2 = selection.Search()) { if (rowCursor2.MoveNext()) { // stop with the first extent Geometry geo1 = (rowCursor2.Current as Feature).GetShape().Clone(); selectionEnvelope = geo1.Extent.Expand(1.1, 1.1, true); } } } } return selectionEnvelope; } }); } public void BuildEnvelopeGeometry() { //Build Envelope Geometry for Main Map Frame Envelope mf_env_Main = EnvelopeBuilder.CreateEnvelope(new Coordinate2D(0.5, 2.5), new Coordinate2D(8.0, 10.5)); //Reference map, create MF and add to layout MapProjectItem mapPrjItem_Main = Project.Current.GetItems<MapProjectItem>().FirstOrDefault(item => item.Name.Equals("Map")); Map mfMap_Main = mapPrjItem_Main.GetMap(); MapFrame mfELM_Main = LayoutElementFactory.Instance.CreateMapFrame(LayoutView.Active.Layout, mf_env_Main, mfMap_Main); mfELM_Main.SetName("Main Map"); } } } ...

Also, now that this code has worked, how can I zoom out a bit more, such as a factor of 2? Thanks! ... View more

Thank you! I will try this as well. ... View more

I apologize. I made a mistake. This worked!!! I greatly appreciate your help. One other question though is how I can get this to work if the project boundary crosses two states (I would need to zoom to two states instead of one). ... View more

I greatly appreciate your assistance on this! I tried the above, and am still not getting the map zoomed to the selected state. Here is what I am getting. NY is selected, which is correct, but the map is zoomed to the entire states layer, not just NY. ... View more

Thanks, I can't seem to get this to work with my example. I can't figure out the code after fl2.Select(spatialQuery);  ... View more
