DocumentViewer上的FlowDocument [英] FlowDocument on DocumentViewer

问题描述

我必须将一个Coded [手段，由C#源代码制作] FlowDocument加载到DocumentViewer

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

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 { }

即使抛出异常，如果我们在Page_Load上调用它，它也可以很好地工作并加载文档.

但是在Button_Click()上不起作用"

我找不到DocumentViewer的任何刷新功能.
Invalidate ...()-函数无济于事.

我正在研究为什么DocumentViewer在设置为Page_Load()而不是Button_Click()时显示FlowDocument的原因.

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?

推荐答案

异常消息告诉您需要一些内容来查看流文档，而不是固定文档....可以使用FlowDocumentScrollViewer，FlowDocumentPageViewer或FlowDocumentReader?

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?
