Remove Export Options From ReportViewer Control

I found this method that will remove export options from a server report when called through ReportViewer. I like this one because you dont need to have a web reference to the SQL server to loop though each rendering extension. How do you call this method if for example, if wanted to remove the XML format from a particular report? I have tried ReflectivelySetVisibilityFalse("XML"), but no luck. Any clues?


private void ReflectivelySetVisibilityFalse(RenderingExtension extension)
{
FieldInfo info = extension.GetType().GetField(€œm_serverExtension€?,
BindingFlags.NonPublic | BindingFlags.Instance);
if (info != null)
{
object actualExtension = info.GetValue(extension);
if (actualExtension != null)
{
PropertyInfo propInfo = actualExtension.GetType().GetProperty(€œVisible€?);
if (propInfo != null && propInfo.CanWrite)
{
propInfo.SetValue(actualExtension, false, null);
}
}
}
}
