Can you also show where you set `SendMouseDown` or did you set it in the properties of the control? ---

I have the same problems with mousedown event in my [VB.NET](http://VB.NET) applications. SendMouseDown=true is set when the tool is selected. In the AxMap control itself, SendMouseDown=false. The ShapeHighlighted event also does not work. Empirically, I determined that if replaced in a compiled project AxInterop.MapWinGIS.dll and Interop.MapWinGIS.dll on older versions 4.9.0, everything starts to work. But after rebuilding the project these events cease to be worked out ---

Well, I admit it is perplexing. At first look, it looks appropriate. I wrote a simple [VB.NET](http://VB.NET) app, and it raises the event just as it should ``` Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load With AxMap1 .Projection = tkMapProjection.PROJECTION_NONE .GrabProjectionFromData = True .SendMouseDown = True .CursorMode = tkCursorMode.cmNone End With End Sub Private Sub AxMap1_MouseDownEvent(sender As Object, e As _DMapEvents_MouseDownEvent) Handles AxMap1.MouseDownEvent Debug.WriteLine("MouseDownEvent") End Sub ``` Perhaps I don’t know enough about c# in this case, but why is the following reference using MapEvents? ``` MapEvents.MouseDownEvent += AxMap1MouseDownEvent; ``` I threw together a quick c# app, and set up the event as follows, using axMap1, not MapEvents: ``` public Form1() { InitializeComponent(); axMap1.CursorMode = MapWinGIS.tkCursorMode.cmNone; axMap1.SendMouseDown = true; axMap1.MouseDownEvent += AxMap1_MouseDownEvent; } private void AxMap1_MouseDownEvent(object sender, AxMapWinGIS._DMapEvents_MouseDownEvent e) { throw new NotImplementedException(); } ``` Respectfully, Jerry. ---

Thank you Jerry i did just like the way you’ve done and it work! ![20191129_105413](https://global.discourse-cdn.com/free1/uploads/mapwindow1/original/1X/4473cb3ec8a4b711b35b62a0363da31ebe02ea78.png) ---

I solved my problem too. This is due to the MapWinGis API update. Maybe someone will find it useful. After updating the MapWinGis API in your projects, check the folders …YouProject\bin\Debug and …YouProject\obj\Debug. In that folders remain old versions of AxInterop.MapWinGIS.dll. Replace them with new versions that can be taken from the folder …YouProject\bin\Release or …YouProject\obj\Release. Now after compiling the project all functions will work ---
