Hi,

how to draw a polyline between two points

Thanks Robert,

I got to work with following code

function init() {

dojo.connect(map, "onLoad", function () {

debugger;
dojo.connect(dijit.byId("map"), "resize", map, map.resize);
var p1 = new esri.geometry.Point(217370.447, 1172344.449, map.spatialReference);
// var p2 = esri.geometry.geographicToWebMercator(new esri.geometry.Point(-90, 40, map.spatialReference));
line = new esri.geometry.Polyline();
line.addPath([p1]);
// lineGraphic = map.graphics.add(new esri.Graphic(line, new esri.symbol.SimpleLineSymbol()));
// map.graphics.add(new esri.Graphic(p1, new esri.symbol.SimpleMarkerSymbol()));
// map.graphics.add(new esri.Graphic(p2, new esri.symbol.SimpleMarkerSymbol()));

dojo.connect(map, "onClick", addPt);
});

}

function addPt(e) {
debugger;
// create a new path using the current line endpoint and the click point
//var p2 = esri.geometry.geographicToWebMercator(new esri.geometry.Point(e.mapPoint.x, e.mapPoint.y, map.spatialReference));
//line.addPath([p2]);
var pathCount = line.paths.length;
line.addPath([line.paths[pathCount - 1][line.paths[pathCount - 1].length - 1],[e.mapPoint.x, e.mapPoint.y]]);
lineGraphic = map.graphics.add(new esri.Graphic(line, new esri.symbol.SimpleLineSymbol()));
lineGraphic.setGeometry(line);
map.graphics.add(new esri.Graphic(e.mapPoint, new esri.symbol.SimpleMarkerSymbol()));
}

 dojo.ready(init);
