Draw a line (graphic) between to sets of coordinates?

I have a workflow that generates to sets of coordinates.  I would like to then draw a line between these two points and add it as a graphic to the map.  Adding points to the map is no problem, but I haven't been able to figure out how to create the line.  I've searched for examples, but I haven't found anything.  Does anyone know where I can find examples of adding linear graphics to a map via a workflow?

 

Thank you,

 

Stephanie

  Hello Stephanie,

  This is currently not possible; I'll create a feature request for this behaviour.

   

  It is possible to snap the plotted coordinates to features within a layer, which you could then snap a drawing between the same two locations.

  Thanks, Stefan

  Hi Stefan

   

  are you saying it is not possible to create a straight line between two points or add linear graphics? As I also would like to add graphics to a worklow (e.g my users create a point and I would like to buffer that point within a range of 150m as a graphic as they need to draw the next point 150m away). I cannot work out a way to do this yet.

  You should first create a PointCollection and fill it with the two points.

   

  http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Geometry.PointCollection.html

   

  Create a new PolyLine and add the pointcollection as a path.

  You could add the line to the viewer with e.g. a Run External Command activity with command AddMarkup, or with the Update Graphics Layer activity.

  Hi Sylvia,

  This is possible through workflow, but not directly on the map using existing tools. Thank you Marshall for providing your sample!
