Is there a way through ArcObjects to run the “Find –Linear Referencing” command? I don’t want to use the locate features tool because I don’t want to create a table. I just want the user to user to change a couple comboboxes on my form and search for a match, then give them the option to flash the location or draw a graphic at that location. Like is done in the bottom of the Find Dialog though I want to use my own form and not the Find Dialog. If this cannot be done in C# and .Net is it possible in Python? Thanks, Craig

I normally use the Silverlight SDK so I understand the map layers and the QueryTask and zooming to the returned features. What I would like to do is have a URL of a java script map that if I pass it the VALUE of a feature in a layer it would open it and zoom to it. I would like a URL something like this "http://myarc.server.com/map?StateName=Texas" In the above example the map would open and then zoom in to the state with the Name = Texas. Is this even possible in java script and if so is there code to show how to achieve this. Thanks for the help, Craig

Thanks you. That sure worked better than my way and you were correct I didnt not need to make a call to the server since i already new the ObjectID. Thansk, Criag

Hello, I have a button that creates a query task and finds a graphic. Now this works fine and on the QueryTask complete I asign the feature to a graphic. Then i try to remove this graphic from the FeatureLayer but it does not remove it. I can break the code and see the new graphic is the right one I want to delete from the feature layer but it does not delete it. Is there something im doing wrong? Thanks for the help, Craig private void btnUploadDelete_Click(object sender, RoutedEventArgs e) { queryTask = new QueryTask(_clientInfo.PlanPointFeatureLayer); queryTask.ExecuteCompleted += QueryTask_ExecuteCompleted; Query query = new Query(); query.Where = "UniqueID = '" + uniqueID + "'"; query.ReturnGeometry = true; query.OutSpatialReference = new SpatialReference(102100); query.OutFields.Add("*"); queryTask.ExecuteAsync(query); } private void QueryTask_ExecuteCompleted(object sender, QueryEventArgs args) { FeatureSet featureSet = args.FeatureSet; Graphic graphic = new Graphic(); if (featureSet != null && featureSet.Features.Count > 0) { foreach (Graphic feature in featureSet.Features) { graphic = feature; } } FeatureLayer fLayer = MyMap.Layers["FeatureLayerPoint"] as FeatureLayer; fLayer.Visible = true; fLayer.Graphics.Remove(graphic); fLayer.SaveEdits(); fLayer.Visible = false; }

Thank you, This is the line of code I needed. "polyline.Paths.Add((e.Geometry as Polyline).Paths[0]);" Craig

Hello All, I???m trying to create a multipart polyline and I am having trouble with it adding connection lines when I add it to the feature layer. I start by adding the line graphic to a PointCollection. ObservableCollection<PointCollection> lpc = new ObservableCollection<PointCollection>(); PointCollection PC = new PointCollection(); void LineDrawingSurface_DrawComplete(object sender, DrawEventArgs e) { GraphicsLayer linegraphicsLayer = MyMap.Layers["LineDrawGraphicsLayer"] as GraphicsLayer; ESRI.ArcGIS.Client.Graphic graphic = new ESRI.ArcGIS.Client.Graphic() { Geometry = e.Geometry, Symbol = MyLineSymbol }; linegraphicsLayer.Graphics.Add(graphic); Polyline PL = graphic.Geometry as Polyline; for (int i = 0; i < PL.Paths.Count; i++) { foreach (var mp in PL.Paths) { PC.Add(mp); } } lpc.Add(PC); } Next I draw two lines on the graphic layer. This shows two separate graphics like I want. Now when I???m done and press the save button I create a polyline and set it to the pointcollection. Then I create a graphic and set is geometry to the polyline. Finally I add the graphic to the featurelayer and save edits. private void btnSave2_Click(object sender, RoutedEventArgs e) { GraphicsLayer linegraphicsLayer = MyMap.Layers["LineDrawGraphicsLayer"] as GraphicsLayer; linegraphicsLayer.ClearGraphics(); Polyline pl = new Polyline(); pl.Paths = lpc; pl.SpatialReference = MyMap.SpatialReference; Graphic graph = new Graphic(); graph.Geometry = pl; FeatureLayer fLayer = MyMap.Layers["FeatureLayer"] as FeatureLayer; fLayer.Graphics.Add(graph); fLayer.EndSaveEdits += Insert_EndSaveEdits; fLayer.SaveEdits(); } Now this all works fine but the problem is the polyline is one continuous line and not two separate lines as a multipart record as originally draw on the graphic layer. I have attached a image of what it is doing. So how can get it to skip the line in the middle when I???m writing the record? Thanks, Craig

Ok this is what i tried it looks like it tries to save it but it doesn't. ESRI.ArcGIS.Client.Geometry.PointCollection point_collection = new ESRI.ArcGIS.Client.Geometry.PointCollection(); ESRI.ArcGIS.Client.Geometry.MultiPoint mp = new ESRI.ArcGIS.Client.Geometry.MultiPoint(); private void btnSaveEdits_Click(object sender, RoutedEventArgs e) { foreach (var p in point_collection) { mp.Points.Add(p); } Graphic graph = new Graphic(); graph.Geometry = mp; graph.Geometry = graph.Geometry; FeatureLayer fLayer = MyMap.Layers["FeatureLayer"] as FeatureLayer; fLayer.Graphics.Add(graph); fLayer.EndSaveEdits += Insert_EndSaveEdits; fLayer.SaveEdits(); } Thanks for your help.

I can use the following code to add a single point to the single point feature layer. private void DrawingSurface_DrawComplete(object sender, ESRI.ArcGIS.Client.DrawEventArgs args) { GraphicsLayer graphicsLayer = MyMap.Layers["DrawGraphicsLayer"] as GraphicsLayer; graphicsLayer.ClearGraphics(); ESRI.ArcGIS.Client.Graphic graphic = new ESRI.ArcGIS.Client.Graphic() { Geometry = args.Geometry, Symbol = MyMarkerSymbol }; graphicsLayer.Graphics.Add(graphic); Graphic graphic2 = new Graphic(); Graphic2.Geometry = graphic.Geometry; FeatureLayer fLayer = MyMap.Layers["FeatureLayer"] as FeatureLayer; fLayer.Graphics.Add(graphic2); } private void btnSave_Click(object sender, RoutedEventArgs e) { FeatureLayer fLayer = MyMap.Layers["FeatureLayer"] as FeatureLayer; fLayer.EndSaveEdits += Insert_EndSaveEdits; fLayer.SaveEdits(); } Now I can change the code to store each point i add to the graphic layer to ESRI.ArcGIS.Client.Geometry.MultiPoint mp = new ESRI.ArcGIS.Client.Geometry.MultiPoint(); point_collection.Add(args.Geometry.Extent.GetCenter()); This give me the collection of my points but i dont know how to save that to a single record in my feature layer. So how do i get my colletion of points to save in the Multipoint feature layer? Thanks, Craig

Thank you Jennifer that is exactly how i set my symbol rotation. I'm sorry to hear its not supported because i use it alot, but thanks for looking into it for me. Craig

I am using a point featureLayer on my map that has symbols matched to a style and rotated on a field. I can see all the symbols just fine on my map but they are not rotated like they were in ArcMap. Does the FeatureLayer not support the rotation on the Rest service? I really dont want to create images of all my fonts in my style to create a unique value renderer. Thanks, Craig
