I'm trying to merge several files into one document, in order to produce a dynamic report.

I can load data into a RadRichTextBox, however after using the code in another forum post, to load another file into a RadDocument object, and then use the Selection.SelectAll method to insert a fragment into the RichTextBox.

private void button2_Click(object sender, RoutedEventArgs e)
        {
            try
            {
  
                RadDocument document2 = new RadDocument();
  
                document2 = ImportRTF();
                document2.Selection.SelectAll(); 
                this.radRichTextBox1.Document.InsertFragment(document2.Selection.CopySelectedDocumentElements());
                }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

The ImportRTF function is:- (and works fine, as it loads a file into the RichTextBox perfectly)
public RadDocument ImportRTF()
{
    try
    {
        RadDocument document = null;
        IDocumentFormatProvider provider = new RtfFormatProvider();
        OpenFileDialog openDialog = new OpenFileDialog();
        openDialog.Filter = "Documents|*.rtf";
        openDialog.Multiselect = false;
        bool? dialogResult = openDialog.ShowDialog();
        if (dialogResult == true)
        {
            //MessageBox.Show(openDialog.File.FullName);
            using (FileStream stream = openDialog.File.OpenRead())
            {
                document = provider.Import(stream);
            }
        }
        return document;
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
         
        return null;
    }
}

However, when calling the SelectAll function on a RadDocument (which isn't a RichTextBox contents) , it doesn't return anything (IsEmpty is True).

Modifying the code to look at the existing RichTextBox contents, and the selection code works fine.

Please help, as it's crucial I can combine document files together.

Thanks

Also, even when working around the issue with an unsatifactory bodge, (by loading the second document into a RadRichTextBox, and calling the UpdateEditorLayout method, and then doing a SelectAll on the RichTextBox's Document), I can't get the fragment to insert at the end of the document.

I have tried using :-
radRichTextBox1.Document.CaretPosition.MoveToLastPositionInDocument();

and also :-

DocumentPosition position = new DocumentPosition(this.radRichTextBox1.Document);
position.MoveToLastPositionInDocument();
radRichTextBox1.Document.InsertFragment(fragment,position);

And neither works, the insertion takes place where the caret is on the UI, regardless of what code-behind does.

Hello AP,

Here how you should modify the code in order to achieve what you want:

private void button2_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                RadDocument document2 = new RadDocument();
 
                document2 = ImportRTF();
 
                //We have to do the following before working with the API of RadDocument
                document2.Measure(RadDocument.MAX_DOCUMENT_SIZE);
                document2.Arrange(new RectangleF(PointF.Empty, document2.DesiredSize));
                document2.Selection.SelectAll();
 
                using (var previousPos = new DocumentPosition(document2.CaretPosition, true))
                {
                    this.radRichTextBox1.Document.CaretPosition.MoveToLastPositionInDocument();
                    //Unfortunately there is problem with the other overload of the method so we have to workaround
                    this.radRichTextBox1.Document.InsertFragment(document2.Selection.CopySelectedDocumentElements());
                    this.radRichTextBox1.Document.CaretPosition.MoveToPosition(previousPos);
                }
 
                this.radRichTextBox1.Focus();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

Let us know if this works for you.

Hi,

We are evaluting RadRichTextBox Control for usage in our project. We are currently using 2011.3.1116.1040 version. Issue is when we try to merge documents, formating is not getting preserved. Font and Size of fonts are rollback to Verdana. Any help?

Thanks,
Shrenik

Hello Shrenik,
You can use the new DocumentFragment constructor:
// you can use other format providers as well
XamlFormatProvider provider = new XamlFormatProvider();
 
List<RadDocument> documents = new List<RadDocument>()
{
    // this will create some test documents that will be merged
    provider.Import(xaml1),
    provider.Import(xaml2),
};
 
RadDocument mergedDocument = new RadDocument();
foreach (var document in documents)
{
    mergedDocument.CaretPosition.MoveToLastPositionInDocument();
    mergedDocument.InsertFragment(new DocumentFragment(document));
}
 
// set the document to RadRichTextBox
this.radRichTextBox.Document = mergedDocument;
If this doesn't help, could you please specify what is the format of the documents (HTML, docx, XAML), or even send it to us so we can investigate the issue further?
