Share Silverlight-based document controls similar to Baidu Library

The general flashpaper supports Word, Excel, and PDF files. Therefore, there are many problems with the support for Silverlight XPS documents. This control provides a visual XPS document display, it provides zoom-in, zoom-out, print-out, search-and-Paging functions, and mainly integrates the open-source document toolkit.

 

1. Document toolkit is used. documentdatasource provides the data source. pagenvaigator provides the following pages:

<DOC: documentdatasourceX: Name= "Datasource"/>

< DOC: documentviewer Grid. Row = "1" X: Name = "Viewer" Documentdatasource =" {Binding elementname = datasource} " Viewmode =" {Binding selectedviewmode, elementname = viewmodepicker} " Borderbrush = "#9fa9a4" Borderthickness = "1" />

< DOC: pagenavigator X: Name = "Navigator" Horizontalalignment = "Center"  
Pagecount =" {Binding pagecount, elementname = viewer} "
Pageindex =" {Binding pageindex, elementname = viewer, mode = twoway} "
/>

< DOC: viewmodepicker Grid. Column = "1" X: Name = "Viewmodepicker" Visibility = "Collapsed" />

 

2. webpackagereader reads local XPS or remote XPS files as the data source

Dotnetzippackagereader load documents based on paging latency

// Loads the sample XPS document from the Web
VaR Url = String . Format ( " /Documentservice. ashx? Id = {0} " , Htmlpage. Document. getelementbyid ( " Entid " ). Getproperty ( " Value " ));
WebClient. openreadasync ( New Uri (htmlpage. Document. documenturi, URL ));

VaRReader =NewWebpackagereader (NewUri (htmlpage. Document. documenturi, URL +"& Part ="));
This. Datasource. packagereader = reader;
VaRXpsclient =NewXpsclient ();
Xpsclient. loadxpsdocumentasync (Reader );

 

3. The server returns the specified file stream based on the requested file ID and current page number.

Private Void Response (httpcontext context, String Xpsfilename, String Partname)
{
Using (Filestream stream = file. openread (xpsfilename ))
{
Zipfile file =New Zipfile (Stream );
Zipentry entry = file. getentry (partname );
If (Entry! = Null )
{
Using (Stream entrystream = file. getinputstream (entry ))
{
// Todo: Set mime-type as defined in XPS package
Context. response. contenttype = " Application/octet-stream " ;
Byte [] Buffer = New Byte [ 2 < 14 ]; // Write blocks of 32768 bytes
Int Read;
While (Read = entrystream. Read (buffer, 0 , Buffer. Length)> 0 )
{
Context. response. outputstream. Write (buffer,0 , Read );
}
}
}
Else
{
// Return 404 not found
Context. response. statuscode = ( Int ) Httpstatuscode. notfound;
}
}

}
