Create Marker on click
posted

Hi,

I've seen the example in your website about markers but it's example with preload markers, and I would know if it's possible to create a marker on the coordonate where I click with the mouse (And clear all markers with button) ?

I've searched but I don't find any example

Thanks and sorry if my question is a little dumb !

    Hello Ezekief,

    You can create a SymbolElement and place it at the location where the end-user clicks. To start, handle the map's MapMouseLeftButtonDown event and track the coordinates where clicked.

    This was previously discussed here:
    https://ko.infragistics.com/community/forums/f/retired-products-and-controls/36373/determine-latitude-and-longitude-on-map-click-event/211645#211645

    Full code example: Placing markers on-click

     private void XamMap1_MapMouseLeftButtonDown(object sender, MapMouseButtonEventArgs e)
            {
                Point mousePosition = e.Position;
                Point mapPosition = xamMap1.Viewport.RootCanvas.RenderTransform.Inverse.Transform(mousePosition);

                SymbolElement element = new SymbolElement()
                { SymbolOrigin = mapPosition, Caption = "Marker", SymbolType = MapSymbolType.Diamond, SymbolSize = 10 };

                xamMap1.Layers[0].Elements.Add(element);
                element.ZIndex = 0;
            }

    Let me know if you have any questions regarding this matter.
