I have to load a Coded[means, making by C# source code] FlowDocument to DocumentViewer

C#
reportView.Document = null;

Matrix rpt = new Matrix(); // This is my FlowDocument

try
{
    reportView.Document = rpt; //This part always throws an exception
    //Exception: DocumentViewer supports only FixedDocument or             FixedDocumentSequence documents.
}
catch { }


Even though it throw exception this works fine and load the document, if we call it on Page_Load.

"But its not working on a Button_Click()"

I couldn't find any refresh function for DocumentViewer.
Invalidate...() - functions not helping.

I am digging into the reason why the DocumentViewer showing the the FlowDocument while we set at Page_Load() and not at Button_Click().

Have any Idea?

The exception message kind of tells you that you need something to view a flowdocument, not a fixeddocument....maybe use a FlowDocumentScrollViewer, FlowDocumentPageViewer, or FlowDocumentReader?

but FlowDocumentPageViewer - (1) doesn't have the print option in-built,
(2) wouldn't have the nice look,
(3) options should be on top [like document viewer]

FlowDocumentReader?

I have tried FlowDocumentPageViewer, FlowDocumentReader, FlowDocumentScrollViewer but I like DocumentViewer

for FlowDocumentReader - IsPrintEnabled property I set to true, still I am not getting print option.

DocumentViewer is the documented wrong element for flowdocuments but if you like it use it.

As for the print option, the docs state "The default toolbar UI does not include a Print button". IsPrintEnabled enables the routed command, that's it.

Mark, I am digging into the reason why the DocumentViewer showing the the FlowDocument while we set at Page_Load() and not at Button_Click().
I appreciate your help and time. Thanks
