Run Report Programatically (Silverlight)

[brigus]

Is there a way to programatically run a report when the parameters change without the user needing to press the preview button.  In my application the users select a row in the datagrid and the report should run and get the corresponding data.  It works the with the first click but it does not run after that because the render begin event is not fired again until preview is pressed.  Also, is there away to change the test on the preview button?

I found the answer.   

 

((

ReportViewerModel)(ReportViewer.DataContext)).ApplyReportParametersCommand.Execute(null);
