Hello,

In our base we save FlowDocument as Text. And i have to display it on Report.
I found this Topic http://forum.stimulsoft.com/viewtopic.p ... ent#p12393.
So i've code this on GetValueEvent :

Code: Select all

byte[] byteArray = System.Text.Encoding.Default.GetBytes(ListeDesMouvementsCaisse.Commentaire);
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);

string str = Stimulsoft.Report.Wpf.StiRtfHelper.ConvertFlowDocumentToRtf(stream); 
e.Value = System.Xml.XmlConvert.EncodeName(StiRichText.PackRtf(str));

But when i made an preview of my report in the designer i have this Report rendering message:

Expression in Text property of 'RichText1' can't be evaluated! Root element is missing.

My FlowDocument is valid because i can display it in my application on a WPF RichTextBox with a string to FlowDocument convert :

Code: Select all

var flowDocument = new FlowDocument();
var valeur = myStringOfFlowDocument;

if (!string.IsNullOrEmpty(valeur))
{
      var stringReader = new StringReader(valeur);
      var xmlTextReader = new XmlTextReader(stringReader);
      flowDocument = (FlowDocument)XamlReader.Load(xmlTextReader);
}

Can you hel me?

Regards,
Morgan SOULLEZ

Hello.

There is Null value in your data in the first report.
Please, try to check it before trying to convert to RTF.

Thank you.

Hello.

We use next code:

Code: Select all

byte[] byteArray = System.Text.Encoding.Default.GetBytes(ListeDesMouvementsCaisse.Commentaire);
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
FlowDocument doc = new FlowDocument();
TextRange documentTextRange2 = new TextRange(doc.ContentStart, doc.ContentEnd);
documentTextRange2.Load(stream, System.Windows.DataFormats.Xaml);

This code load text from FlowDocument. But we don't see any text in the Debug mode.

Thank you.

Hi,

I've resolved my problem !

With this source code :

Code: Select all

if (!string.IsNullOrEmpty(ListeDesMouvementsCaisse.Commentaire))
{
      var flowDocument = new System.Windows.Documents.FlowDocument();
      var stringReader = new System.IO.StringReader(ListeDesMouvementsCaisse.Commentaire);
      var xmlTextReader = new System.Xml.XmlTextReader(stringReader);
      flowDocument = (System.Windows.Documents.FlowDocument)System.Windows.Markup.XamlReader.Load(xmlTextReader);
      var tr = new System.Windows.Documents.TextRange(flowDocument.ContentStart, flowDocument.ContentEnd);
      var stream = new System.IO.MemoryStream();
      tr.Save(stream, System.Windows.DataFormats.Xaml);
      var str = Stimulsoft.Report.Wpf.StiRtfHelper.ConvertFlowDocumentToRtf(stream);
      e.Value = System.Xml.XmlConvert.EncodeName(Stimulsoft.Report.Components.StiRichText.PackRtf(str));
}

And with this ReferencedAssemblies :

Code: Select all

System.Dll
System.Drawing.Dll
System.Windows.Forms.Dll
System.Data.Dll
System.Xaml.dll
System.Xml.Dll
PresentationCore.dll
PresentationFramework.dll
WindowsBase.dll
Stimulsoft.Controls.Dll
Stimulsoft.Base.Dll
Stimulsoft.Report.Dll
Stimulsoft.Report.Wpf.dll
