how reference boolean custom renderer?

you need store isfirehazard passed constructor in custommap object member. in custommaprenderer can access

protected override void onelementchanged (elementchangedeventargs<xxx> e)     {        base.onelementchanged(e);         if (e.newelement != null)        {           var formsmap = (cusommap)e.newelement;           if(formsmap.isfirehazard)           {           }        }     }
