Convert mailmerged RadDocument to RadFlowDocument

Hi,

I try to do the following:

1. Load .docx document into the RichTextBox

2. Let the user edit the document

3. Perform MailMerge on the document

4. Export the result as PDF witha compliance level PdfComplianceLevel.PdfA1B

Only the WordsProcessing library supports the compliance level, so I need to convert the RadDocument to a RadFlowDocument.

When I export the RadDocument from the RichTexBox back to .docx I somehow loose all the styles (See WordBefore.png, WordAfter.png).

When I export the RadDocument to .rtf, it keeps the correct styles, but when I import it using the Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider, I get the following Exception:

Message: The document element is already associated with a parent.

Parametername: item

StackTrace:   bei Telerik.Windows.Documents.Flow.Model.Collections.DocumentElementCollection`2.VerifyDocumentElementOnInsert(T item)

bei Telerik.Windows.Documents.Core.Data.DocumentElementCollectionBase`2.Add(T item)

bei Telerik.Windows.Documents.Flow.FormatProviders.Rtf.Import.RtfDocumentImporter.DoVisitGroup(RtfGroup group)

bei Telerik.Windows.Documents.Flow.FormatProviders.Rtf.Import.RtfElementIteratorBase.VisitElement(RtfElement element, Boolean recursive)

bei Telerik.Windows.Documents.Flow.FormatProviders.Rtf.Import.RtfElementIteratorBase.VisitGroupChildren(RtfGroup group, Boolean recursive)

bei Telerik.Windows.Documents.Flow.FormatProviders.Rtf.Import.RtfDocumentImporter.ImportRoot(RtfGroup rtfGroup)

bei Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider.ImportOverride(Stream input)

bei Telerik.Windows.Documents.Common.FormatProviders.FormatProviderBase`1.Import(Stream input)

...

Do you have any proposal for me how I can accomplish this?

Import a PDF exported rom GridView ExportToPdf

Hello,

I am trying to:

1 - Open a PDF created from Gridview's ExportToPdf function

2 - Draw a title on the page

3 - Save the PDF

When I run my code everything executes, but the final PDF is a blank page, but with the same length as the original PDF.

If I only open the page and then immediately save the PDF without attempting to draw on the page, the result is the same.

First, can PDFProcessing do this? I've heard that not all of your various PDF exports are compatible with all of the imports yet.

If that is the case, do you have an alternate way for me to get some title text on the PDF file generated by GridView's ExportToPdf function?

Thanks in advance,

Scott

Table Headers & Page numbers

I really like the Telerik DPL and I'm using RadFlowDocument with PdfFormatProvider to produce some much need PDFs, but I've got 2 major issues:

1). The tables (Table table = section.Blocks.AddTable();) don't seem to support any sort of Table Headers, I want it to simply repeat the table headers when it flows onto another page. Much like itextsharp's setHeaderRows(). Is this possible?

2) There doesn't seem to be any support for pages numbers in the footer?

Thanks,

PDF Missing images in Internet Explorer.

Hi there!

So I'm using kendo.drawing.drawDOM() to Export a <div> area on page to a PDF, this works great in my versions of Firefox and Chrome. However in IE 11, its not grabbing the backgrounds of a few divs in the area. This chart area is created problematically, and the "water bottle" columns are being shown based on a height that is calculated by the values...anyway.

While testing, I determined it was most likely the background-image that isn't getting pulled correctly. I added a new div with the same class and that one too, failed to be copied into the PDF. I tried swapping out the div with an <img> tag, and while that worked for the pdf export...I lost a bunch of the flexibility of having the image in a div. The image came out streched and generally not what I wanted.

Any ideas for what I can do to make this work in IE?

The html for each column looks something like this:

The CSS:

div.WaterBottleColumn {
background-repeat: no-repeat;
background-position: center top;
margin-left: auto;
margin-right: auto;
}

I did have the background-image declared in the CSS class, but I moved it when I was troubleshooting.

Thanks!

Looking for workable zip example.

Hi,

I red all documentation and all forum's threads and didn't find a complete workable example that compress/decompress a stream . Every founded examples did not work well. Is it possible to have a complete example closer to a cut and paste?

Regards,

I put my code here. It compresses but the decompression is not functionnal:

Public Class Class1

Dim msCompress As Stream

Public Function Compression(arg As String) As String

Dim encoding As New System.Text.UTF8Encoding()

Dim B() As Byte = encoding.GetBytes(arg)

msCompress = New MemoryStream()

Dim method As ZipCompression = DirectCast([Enum].Parse(GetType(ZipCompression), ZipCompression.Deflate64, False), ZipCompression)

Dim zipOut As New ZipOutputStream(msCompress, method)

Dim sWriter As New StreamWriter(zipOut)

sWriter.Write(B)

sWriter.Flush()

Return ("Compress: " & zipOut.CompressedSize.ToString & ", Uncompress:" & zipOut.UncompressedSize.ToString)

End Function

Public Function Decompression(arg As String) As String

Dim encoding As New System.Text.UTF8Encoding()

msCompress.Position = 0

Dim inputStream As New ZipInputStream(msCompress, False)

Dim s As String

Dim Reader As New StreamReader(inputStream.BaseStream, encoding)

s = Reader.ReadToEnd()

Return s

End Function

End Class

Adding page number to footer of RadFlowDocument

Hi,

I am working on a project to programmatically create reports using RadFlowDocument. I could not find a way to add page number to footer of the document.

I came across this link: http://www.telerik.com/forums/adding-page-number-in-the-footer. But it shows how to add page number from the RadRichTextBox using RadDocument.

I would appreciate if you can help me with this.

Thanks,

Sujan

Telerik.Windows.Documents.Flow.Model.Table newTable = editor.InsertTable(1, 2);

newTable.Rows[0].Cells[0].Borders = new TableCellBorders( new Telerik.Windows.Documents.Flow.Model.Styles.Border(1, Telerik.Windows.Documents.Flow.Model.Styles.BorderStyle.Single, ThemableColor.FromArgb(100, 0, 100, 0)), new Telerik.Windows.Documents.Flow.Model.Styles.Border(1, Telerik.Windows.Documents.Flow.Model.Styles.BorderStyle.None, ThemableColor.FromArgb(100, 0, 100, 0)), new Telerik.Windows.Documents.Flow.Model.Styles.Border(1, Telerik.Windows.Documents.Flow.Model.Styles.BorderStyle.Single, ThemableColor.FromArgb(100, 0, 100, 0)), new Telerik.Windows.Documents.Flow.Model.Styles.Border(1, Telerik.Windows.Documents.Flow.Model.Styles.BorderStyle.Single, ThemableColor.FromArgb(100, 0, 100, 0)));

how to start insert text in a new DOCX page A4 ?

I use there code to make a docx file

RadFlowDocument document = new RadFlowDocument();

RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);

editor = new RadFlowDocumentEditor(document);

editor.insertText("this is page 1 ");

// but the problem is I want to insert text in another A4 page like

editor.insertText("this is page 2 ");

According to the document telerik I found that we can set up "section" for A4 page

http://docs.telerik.com/devtools/aspnet-ajax/controls/wordsprocessing/model/section#rotating-a-section

but I think I don't understand how to use it please help !!

Section section = new Telerik.Windows.Documents.Flow.Model.Section(document);

document.Sections.Add(section);

section.PageMargins = new Telerik.Windows.Documents.Primitives.Padding(40, 10, 40, 10);

section.PageSize = PaperTypeConverter.ToSize(PaperTypes.A4);//WindowsBase assembly should be referenced.

editor.InsertSection();

editor.InsertText(("Page 2 !!"));

and is it possible that we know what is the current page number before "insertText" ?
