Create hyperlink for objects on map layout (labels first of all, graphics...) 1/ When we export map pages to one PDF document with Data Driven Page we can have hyperlink on pages to navigate top/bottom/left/right/index page 2/ We can add hyperlink to the site for company name label or logo picture we all use hyperlinks in other types of documents, why not in the map? ...

Thank you, Dmitry! I'll try your solution. I got this problem only on 9.3.1 server. On AGS-10 directions returned with decimals in coordinates.  Maybe this is about different locale(Russian) on server: comma( ",") as decimal separator? But I changed locale settings for SOC user with no result. ... View more

My solution: populate properties of route parameters                _routeParams.DirectionsLengthUnits = esriUnits.esriMiles;                 _routeParams.ImpedanceAttribute = "Minutes";                 _routeParams.OutputLines = "esriNAOutputLineTrueShape";                 _routeParams.OutSpatialReference = new  ESRI.ArcGIS.Client.Geometry.SpatialReference( 4326);                 _routeParams.UseHierarchy = false; // true by default and i have no Hierarchy in my network. Here was an error ... View more

excellent solution! I've read in on-line help "...If you need to change spatial reference on the fly, you can instead create a new map instance, move the layers to this map, and replace the previous map instance..." It has misled me set extent =null and  layers=null is enough ... View more

Hi, Jennifer! I want to continue this thread (or create new one?) In this example we know events of the current map object. But in the general case we don't know about all attached events of the object. So before creating new instance it will be good idea to copy event handlers from old map to somewhere (?) and restore them in new map. How make this? Secondly, in XAML I have event triggers [HTML]            <i:Interaction.Triggers>                 <i:EventTrigger EventName="MouseClick">                     <ei:ChangePropertyAction TargetName="myMenuItems" PropertyName="Visibility">                         <ei:ChangePropertyAction.Value>                             <Visibility>Collapsed</Visibility>                         </ei:ChangePropertyAction.Value>                     </ei:ChangePropertyAction>                 </i:EventTrigger>             </i:Interaction.Triggers> [/HTML] new map also must have triggers. How to restore this part of code? 3/ also the "problem" with Map Properties Eventually we have a problem with cloning of map object (or collections of events, triggers,properties, what else?) in addition. If the reference to the old map is still exists, maybe necessary remove events handlers from it? to prevent raise of events twice. Or kill old map? ... View more

Well, so when i create new map I must give this instance the name of the previous map and set all parameters and attach events. All like in the previous map. Is it correct? thank you very much! ... View more

Thank you Jennifer! this code works nice! I've found that after recreating the map with Mercator projection MyMap.Extention still -180+180 and -90+90. That was my error. I used the wrong variable. Please explain me difference between this.MyMap and this.LayoutRoot.Children[0]. When I must use the first reference? ... View more

Hi, Jennifer! 1/collLayers is the LayerCollection -copy of layers of the map 2/Map.Layers.Clear() don't modify this collection 3/collLayers["BaseLayer"] is the previous tiled layer in the map and lyr - is new tiled layerwith different projection. 4/ lyr has been Initialized, and I set spatial reference to  TileInfo too 5/ I know that I can't mix tiled layers, so i try recreate the map 6/ after this line map.resolution still null, I think this is a problem                 Map = new ESRI.ArcGIS.Client.Map()                 {                     Extent = lyr.FullExtent,                     Visibility=Visibility.Visible,                     MaximumResolution=((TiledMapServiceLayer)lyr).TileInfo.Lods[0].Resolution ,                     MinimumResolution = ((TiledMapServiceLayer)lyr).TileInfo.Lods[((TiledMapServiceLayer)lyr).TileInfo.Lods.Length-1].Resolution                 }; 7/ I've tried add only ArcGISDynamicMapServiceLayer (SR -102100) in the new map, but have the same problem - no layers visible. Do you know public tiled layer somewhere on internet with projection different 102100 to test application with it? Or may be you have correct  code for creating new map instance. Thank you. ...
