I think the problem comes from the confusion that ZoomToResolution doesn't center on the point you specify. It only zooms "around" that point. It's for instance the method that is used when you dblclick or mousewheel zoom. Try to do that up in the corner of the map, and you will notice that the map doesn't center on the point you dblclick, however the point instead stays under your mouse cursor. If you need to zoom and center on a point, create an envelope around the point (the envelope must have a width or height>0) and zoom to that using the "ZoomTo" method. ... View more

This is some of the very basic of Silverlight development, so I would suggest you look through the tutorials on Silverlight, especially #3 and #4: http://www.silverlight.net/learn/quickstarts/ and http://weblogs.asp.net/scottgu/pages/silverlight-tutorial-part-6-using-user-controls-to-implement-master-detail-scenarios.aspx On a side note the sample you refer to is a very advanced sample. If this is among your first ventures into Silverlight, you are in for a challenge 🙂 The "sample" is nver built to be reused or customized. It's just a sample that showcases some of the features that the API can do. It's not a very good end-user app. ... View more

Not sure exactly what you want. I can't give you details on the entire application (that would take me half the day). But the gist of it is that I use a QueryTask in a DispatcherTimer that triggers every few seconds and requests all features where TimeStamp>lastRequestTimeStamp in the where clause (there's a timestamp attribute on my features). I then go through each feature in the GraphicsLayer, check its graphics id and see if I got that ID back from the server. If I did, I'll update it's geometry property. ... View more

This is something we are investigating and thinking about, but I can't share any details at this time. ... View more

We will have that available out of the box in our next release. ... View more

I think you can use a string format in the binding too to accomplish that. Ex: Source="{Binding Binding [ProjectID], StringFormat=Images/{{0}}}" ... View more

If you start out with a new ESRI Silverlight Standard Map Template project in Visual Studio or Expression Blend, there is two such type of toolbars under the title box. You can copy that approach to your own toolbar. ... View more

Note that "/Images/IdentifyMapIcon.png" is relative to where the .xap file is, not where the hosting html file is. ... View more

WKT and WKID should not affect this part of the map at all (it's really only the layers that are affected by this). Could you share some code? There could be several reason why nothing happens (ie parsing in the same resolution as the current map resolution, hitting the limit of the min/max map resolution etc). ... View more

I've done this before. Basically I every few seconds request the ID and location of all features that have changed since the last request. I then go through the graphics that matches the returned IDs and update their Geometry property (changing the geometry automatically updates their position on the map). You can even create a little loop that animates X and Y from the old to the new position, to give a sense of "movement". ... View more

Did you reproject the geometries coming from the GeoRSS feed to WebMercator using the ESRI.ArcGIS.Client.Projection.WebMercator class? ... View more

For production setups, you will need to use the geometry service on your own ArcGIS Server instance. ... View more

I would put it this way: If your webapplication uses so much memory that you require to run it on 64bit, your app is doing something very wrong 🙂 ... View more

You can't reference target names across XAML files. If you need a reference, create a property on the controls that you can use as a "binding bridge" between them. ... View more
