Help on Arcgis Api for silverlight

[IvanKarlsson]

A month ago I and my partner started a final project, we building information system for a farm that is based on Arcview 9.3. It is going to be a web site at the end (hopefully). We already have a database and maps, and we're trying to establish connection between the data base that we have and silverlight app. And we're little bit lost on it. Any help will be usefull.

Have you looked at the Interactive SDK/Demo? It's should be helpful. Here's the link: http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/samples/start.htm

Also some description of what your trying to do would help in getting responses.

What i'm trying to do is toconnect some data base that i have(an access data base) to the map and build an form where i could choce a poligon on a map and when ever i chose one I'll be able to manipulate the data from a db.I saw the demo and it was usefull but i couldn't fint any apropriate help file that explains how can i work with the api . I'm kind of lost in GIS jungle :(.

I'm still new to this is as well. We are doing something similar to what you're asking.

I'm sure there are ways to do what your talking about via ArcGIS, but I've not gone that route, primarily due to me not knowing anything at all about spatial things.

You'll need to write some type of web service that acts as middle man to the database and the Silverlight client.  For this, we are using WCF RIA to get data in and out of our SQL database. When I get my lat/lon values from my database, I build ESRI Graphic objects and add them to the GraphicsLayer of my map. Sometimes I build my own custom MarkerSymbols in the XAML if I need something more than a point or polygon.

You don't need to use WCF RIA to access your Access ;), you can use "plain" WCF, or by using the WebClient/HTTPRequest in Silverlight to access pretty much any HTTP based service to pass data and requests in and out of your database.

Quite frankly coming from a .NET developer standpoint, ESRI's approach is not the most intuitive at first, but you can get the hang of it. But if you're coming from a GIS background, I sure it makes more sense.

These are good responses and if I may add, please also visit our Concepts page, this includes GettingStarted document. http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/help/index.html

If you are using 9.3, you should visit: esriurl.com/slsdk, for 10, you should visit esriurl.com/slsdk2.

Let me add to Jennifers comment by saying that the v2.0 of the API is fully compatible with ArcGIS 9.3.x, so you don't have to use the old v1.x of the API.
