Hi
i am working in mvc and and printing map to pdf
Issue i am facing is i am trying to add scale bar on my pdf after printing …
It adds ShapeOverlay, WorldMap and LayersOverLay correctly
But when i try to add adornment layer and and marker over it gives me error
“The given key was not present in the dictionary.”
how can we loop through in memorymarkeroverlay to make them visible when it goes for printing
Here is the print function
public string MapPrint(Map map, GeoCollection<object> args)
{
PdfGeoCanvas pdfGeoCanvas = new PdfGeoCanvas();
PdfDocument document = new PdfDocument();
PdfPage page = document.AddPage();
page.Orientation = PageOrientation.Portrait;
page.Size = PageSize.A4;
string font = "Roboto";
string Area = "";
List<LayerOverlay> lstlayeroverlay = new List<LayerOverlay>();
List<InMemoryMarkerOverlay> lstmarkeroverlay
= new List<InMemoryMarkerOverlay>();
//AdornmentOverlay adornmentoverlay = new
AdornmentOverlay();
List<LegendResult> lstlegend = new List<LegendResult>();
lstlayeroverlay.Add((LayerOverlay)map.CustomOverlays["WorldMap"]);
lstlayeroverlay.Add((LayerOverlay)map.CustomOverlays["LayersOverlay"]);
lstlayeroverlay.Add((LayerOverlay)map.CustomOverlays["ShapeOverlay"]);
//
lstlayeroverlay.Add((LayerOverlay)map.CustomOverlays["ScaleBar"]);
lstmarkeroverlay.Add((InMemoryMarkerOverlay)map.CustomOverlays["GirlsMarkerOverlay"]);
lstmarkeroverlay.Add((InMemoryMarkerOverlay)map.CustomOverlays["BoysMarkerOverlay"]);
lstmarkeroverlay.Add((InMemoryMarkerOverlay)map.CustomOverlays["MixMarkerOverlay"]);

Please mention if i am wrong somewhere
