Got a problem. I have an asp.net mvc app where I need to display a map zoomed to the extent of a number of features.  So what I did was union all the features together using DbGeometry on the server side, and then passed the envelope object to the client as a WKT and use that to compute the map extent as shown below:  require(["dojo/parser", "dijit/layout/TabContainer", "dijit/layout/ContentPane"]); 　 var mapArgs = { sliderStyle: "small", sliderPosition: "top-right", basemap: "topo" } //get the default extent, if specified var parser = new geometryWktParser(); var defaultBounds = parser.loadPolygonGeographic('@Model.qdArcsExtent'); mapArgs.extent = defaultBounds.getExtent(); 　 //build the map require(["esri/map", "dojo/domReady!"], function (Map) { map2 = new Map("qdMap", mapArgs); Well, this doesn't seem to work real well. The map extent is either off center from where it should be or not big enough to display all the features - or both.  Sometimes it isn't off by much, but other times it's wildly off. So I tried using DbGeography instead of DbGeometry, but DbGeography doesn't have any kind of envelope or extent.  So then I tried SqlGeography.  SqlGeography has EnvelopeCenter and EnvelopeAngle.  How would I use these to compute the map extent on the client side - is it even possible? ...

I have a dbGeometry object in C#.net that is basically a union of several other dbGeometry objects.  I need a way to get the extent of this unioned object.  Any ideas as to the best way to handle this? ... View more

I'm trying to get two maps to work on one page and so far haven't been successful.  The best I have been able to obtain is one map having the basemap loaded and the other map having all the layers loaded.  I've put unique id's on all the div's associated with the maps.  Is there something else that needs to be done to make sure esri can distinguish between them? ...
