copied!<p>You can add the <code>DataSourceController</code> as a resource (you'll have to do this from code-behind if you don't have a parameterless constructor) and use the <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.objectdataprovider.objectinstance.aspx" rel="nofollow noreferrer">ObjectDataProvider.ObjectInstance</a> property to get the <code>DataSourceController</code> instance, then you can execute methods on it:</p> <pre><code>private ISQLConnection conn; public ISQLConnection SqlConnection { get { return conn; } } private DataSourceController dataSource; public DataSourceController DataSource { get { return dataSource; } } protected override void OnStartup(StartupEventArgs e) { //------------------------------------------------------- // Initialize connections conn = new OracleSQLConnection("connectionStringHere"); //------------------------------------------------------- // Initialize controllers dataSource = new DataSourceController(conn); this.Resources.Add("myDataController", dataSource); base.OnStartup(e); } </code></pre> <p><code>ObjectInstance</code> can take a resource:</p> <pre><code><ObjectDataProvider ObjectInstance="{StaticResource myDataController}" x:Key="DataSource" MethodName="GetVenues" /> </code></pre> <p>There might be issues if your <code>ObjectDataProvider</code> is in App.xaml where it could be parsed before the <code>DataSourceController</code> resource is added, in which case you'd get an error because the "<code>myDataController</code>" resources wouldn't exist yet.</p>
