The call to the ShowDialog method was not made from user-initiated code.
Use the return value of the ShowDialog method to determine whether the user selected a file.
The ShowDialog method can only be called from user-initiated code, such as a button Click event. If ShowDialog is called from code that is not user-initiated, such as a Page Loaded event, a SecurityException is thrown.
The Silverlight plug-in does not support OpenFileDialog in full-screen mode. In most cases, displaying this dialog box in full-screen mode will cause the plug-in to revert to embedded mode. To avoid issues on some browsers, you should exit full-screen mode before using this class. For more information, see Full-Screen Support.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
