Hi,
I have the need to obtain the raw text value from a RichtextBox, but I do not have a visual object to use. I have the content of the RTB in DataFormats.XamlPackage (not .Xaml so I can support images), and if I use a visual component I (FlowDocument, TextRange etc) I can reconstitute the RTB and get the raw Text from it (or the textRange).
However, I was hoping to do this non-visually using the DatObject class, as so:
DataObjectxaml=newDataObject(DataFormats.XamlPackage, text);text=xaml.GetText();
I always seem to get an empty string.
The follwing works:
TextRangetr=newTextRange(Document.ContentStart, Document.ContentEnd);MemoryStreammsOut=newMemoryStream(ASCIIEncoding.Default.GetBytes(text));msOut.Seek(0, System.IO.SeekOrigin.Begin);tr.Load(msOut, DataFormats.XamlPackage);
assuming 'this' is a RichTextBox and I can objtain the Text property from the TextRange tr.
The following similar code results in an exception:
FlowDocumentfd=newFlowDocument();TextRangetr=newTextRange(fd.ContentStart, fd.ContentEnd);MemoryStreammsOut=newMemoryStream(ASCIIEncoding.Default.GetBytes(text));msOut.Seek(0, System.IO.SeekOrigin.Begin);tr.Load(msOut, DataFormats.XamlPackage);
the last line generates an "Unable to read beyond the end of the stream" exception.
Does anyone have an idea how I can get the text in this situation?
Cheers,
Radek
