wpf - PageBreak in flow documents at runtime -

this first post.... have problem in task…..iam able text file on flow document have divide contents in proper pagebreaks @ runtime i.e if contents huge shud in number of pages @ runtime.

please help….. iam attaching initial code:

using system; using system.collections.generic; using system.linq; using system.text; using system.windows; using system.windows.controls; using system.windows.data; using system.windows.documents; using system.windows.input; using system.windows.media; using system.windows.media.imaging; using system.windows.navigation; using system.windows.shapes;  namespace textonflowdoc {     /// <summary>     /// interaction logic page1.xaml     /// </summary>     public partial class page1 : page     {         public page1()         {             initializecomponent();             paragraph paragraph = new paragraph();              paragraph.inlines.add(system.io.file.readalltext(@"c:\lis.txt"));             paragraph.fontfamily = new fontfamily("couriernew");              flowdocument document = new flowdocument(paragraph);             // flowdocumentreader rdr = new flowdocumentreader();             flowdocscl.document = document;         }     } } 

now "flowdocscl" flow document , needs breaked pages @ runtime. in advance.

thanks lot advice. have used code in following manner , achieved wanted.

        var pages = ts.split(new string[] { "\f" }, stringsplitoptions.none);          (int = 0; < pages.length; i++)         {             if (i != pages.length - 1)             {                 cmbpagenbr.items.add(i + 1);             }         }          if (cmbpagenbr.items.count > 0)         {             cmbpagenbr.selectedindex = 0;         }         loadpagewisedata(cmbpagenbr.selectedindex);     }      private void loadpagewisedata(int pagenbr)     {         var pages = ts.split(new string[] { "\f" }, stringsplitoptions.none);         flowdocument document = new flowdocument();         document.blocks.add(new paragraph(new run(pages[pagenbr])) { breakpagebefore = true });         document.fontfamily = new system.windows.media.fontfamily("courier new");         document.fontsize = 12;         docviewer.document = document;     }
