NoError No error.
UnknownError Error is unknwon.
InitializeError Error occurred during initalization.
ParserError Error occurred during the parsing of XAML content, at a level before the object model was incorporated. For example, tag mismatches in XML.

See Silverlight Application Scripting Error Handling to learn more about using values of this enumeration.

Examples

The following JavaScript example shows how to create an onError event handler that displays error information specific to the type of error that occurred. The ErrorType property on the ErrorEventArgs is used to determine the type of error.

JavaScript 
function OnErrorEventHandler(sender, errorArgs)
{
    // The error message to display.
    var errorMsg = "Silverlight Error: \n\n";
    
    // Error information common to all errors.
    errorMsg += "Error Type:    " + errorArgs.errorType + "\n";
    errorMsg += "Error Message: " + errorArgs.errorMessage + "\n";
    errorMsg += "Error Code:    " + errorArgs.errorCode + "\n";
    
    // Determine the type of error and add specific error information.
    switch(errorArgs.errorType)
    {
        case "RuntimeError":
            // Display properties specific to RuntimeErrorEventArgs.
            if (errorArgs.lineNumber != 0)
            {
                errorMsg += "Line: " + errorArgs.lineNumber + "\n";
                errorMsg += "Position: " +  errorArgs.charPosition + "\n";
            }
            errorMsg += "MethodName: " + errorArgs.methodName + "\n";
            break;
        case "ParserError":
            // Display properties specific to ParserErrorEventArgs.
            errorMsg += "Xaml File:      " + errorArgs.xamlFile      + "\n";
            errorMsg += "Xml Element:    " + errorArgs.xmlElement    + "\n";
            errorMsg += "Xml Attribute:  " + errorArgs.xmlAttribute  + "\n";
            errorMsg += "Line:           " + errorArgs.lineNumber    + "\n";
            errorMsg += "Position:       " + errorArgs.charPosition  + "\n";
            break;
        default:
            break;
    }
    // Display the error message.
    alert(errorMsg);
}
