    XML DataSource - General information

    The XmlDataSource control is a data source control that presents XML data to data-bound controls. The XmlDataSource control can be used by data-bound controls to display both hierarchical and tabular data.

    This article is taken from JavaScript @ Wikibooks.

But when you code, you have to make sure that you are getting the right type at the right time. Variable declaration Variables are commonly explicitly declared the var statement, as shown below: var c; .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The above variable is created, but has the default value of undefined.

    So if you’re like me, you’re on board with Silverlight and looking to get the most out of your RIA development.  I’ve taken all the advice offered for creating Silverlight apps with WCF services- this video by Tim Heuer has been indispensable, but now we can create a Silverlight Enabled WCF service to avoid the modifications in web.config.
