Hi.  I'm creating a series of MapTools to sketch a line on the map that will represent a new feature.  A criteria of the sketch is that the first node of the sketch must intersect a line feature.  So for example, to create a hydrant lateral the first click must intersect a watermain....the second click will represent the hydrant valve and the last the hydrant. I have created a routine for checking for the intersection of the first click to a given layer, but I am getting mixed results.  With certain layers it works (ie.  my sewer layer for my sewer connection tool), but other layers (ie. my watermain layer for my hydrant tool).  Here is the code: public static bool IntersectsLayer(MapPoint point, FeatureLayer layer) { try { SpatialQueryFilter spatialFilter = new SpatialQueryFilter(); spatialFilter.FilterGeometry = point; spatialFilter.SpatialRelationship = SpatialRelationship.Intersects; RowCursor theCursor = layer.Search(spatialFilter); Feature feature; while (theCursor.MoveNext()) { using (feature = (Feature)theCursor.Current) { return true; } } } catch (Exception ex) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(ex.ToString()); } return false; }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And here is the code that calls it: protected override Task<bool> OnSketchCompleteAsync(Geometry geometry) { //use the sketch geometry to create the connectionPoint, valve and hydrant var pointCollection = ((Multipart)geometry).Points; MapPoint connectionPoint = pointCollection[0]; MapPoint hydrantPoint = pointCollection[pointCollection.Count - 1]; MapPoint valvePoint = pointCollection[1]; //start creating the features QueuedTask.Run(() => { if (Global.IntersectsLayer(connectionPoint, waterMainLayer) == false) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(connectionPoint.X.ToString() + ", " + connectionPoint.Y.ToString(), "Error"); ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("The starting point must intersect the WaterMain or Water Service layer.", "Error"); return; } .......‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Can anyone see anything wrong in the code?  For some reason it always returns false when using the watermain layer.  I have snapping turned on, and it always works when using my similarly coded sewer connection tool. Any ideas are appreciated. ... View more

Hi, So in my application the user selects multiple sewer lines to start.  I then have a dockpanel that gets regfreshed to show the ID of the users selection in a listbox.  Now what I want is that when the user selects the ID of one of the lines in the dockpanel, that the selection in the map changes to show only that line as selected.  I am doing all of my coding for this in the _SelectionChanged event of the list, but running into a "The calling thread cannot access this object because a different thread owns it." error. What can I do to get around this?? After clicking on one of the ID's in the listbox below is when the error comes up. Thanks, ... View more

Hi, I've created a tool that draws graphics (Overlay) onto the screen to help identify sewer connections.  It's all working fine....most of the time.  See below for an example.  What I am finding is that in some .aprx files the graphics draw fine, but in others they do not.  I think it may be a case of when the .aprx is created by importing an old .mxd document into ArcGIS Pro.  Does anyone know if that might be the cause??  Or should I be looking something else?? With a 'pure' .aprx file, no problems (ie. the red arrows get drawn): With an imported .mxd to .aprx file, problems (ie. no graphics get drawn): ... View more
