I can't add the HTML in a table for wordsporcessing

First I create the table by editor like this

RadFlowDocument tableDoc = new RadFlowDocument();

RadFlowDocumentEditor editor = new RadFlowDocumentEditor(tableDoc);

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)));

and prepare the html string (with convert function) like this

string html = "<p>HTML STR 1234<span style=\"line-height:20px;\">1234 1234 </span></p>";

HtmlFormatProvider providerHtml = new HtmlFormatProvider();

RadFlowDocument document = providerHtml.Import(html);

but I don't know how to put " RadFlowDocument " into table I 'm already try this but it show some error "The document element is associated with another document.
Parameter name: item" . Please Help!!

Paragraph paragraph = new Paragraph(document);

newTable.Rows[0].Cells[0].Blocks.Insert(0, paragraph);

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" ?

Merge operation works to slow

Hi,

I`m playing with Excel export task using SpreadProcessing.

I`ve notice that when i`m using merge for cellSelection - time needed to write to workbook increases dramatically.

I made simple test - cycle with 10000 inserts operations and merges of two cells (horizontal merge).

The results for cycle:

- with merge takes 00:00:06.3593555

- without merge takes 00:00:00.1815065

My code:

var workbook = CreateWorkbook();

workbook.History.IsEnabled = false;

workbook.SuspendLayoutUpdate();

var worksheet = workbook.ActiveWorksheet;

for (int i = 0; i < 10000; i++)

{

CellIndex cellIndex = new CellIndex(i, 0);

worksheet.Cells[cellIndex].SetValue("Data " + i);

worksheet.Cells[cellIndex].SetHorizontalAlignment(RadHorizontalAlignment.Left);

worksheet.Cells[i, 0, i, 2].MergeAcross();

}

workbook.ResumeLayoutUpdate();

workbook.History.IsEnabled = true;

Although, I made test with merge from 0 to 8 column. Result - 00:00:15.4579052.

Is there any workaround of such perfomance issue?

PdfFormatProvider // Exporting multiple HTML pages

A web based application, I am working on, must provide users with the ability to export a collection of articles to one single PDF document. This articles contain HTML code for formatting the text as well as positioning of various parts of the article.

Below is the code which I came up with for Exporting one single article:

var html = File.OpenText(artPath).ReadToEnd();
var buffer = new byte[0];

var pdfProvider = new PdfFormatProvider();
var htmlFormatProvider = new HtmlFormatProvider();

HtmlImportSettings importSettings = new HtmlImportSettings();
importSettings.UseHtmlHeadingStyles = true;

htmlFormatProvider.ImportSettings = importSettings;

var document = htmlFormatProvider.Import(html);
document.LayoutMode = DocumentLayoutMode.Paged;
document.EnsureDocumentMeasuredAndArranged();

buffer = pdfProvider.Export(document);

using (var fs = new FileStream(pdfDocPath, FileMode.Create, FileAccess.Write, FileShare.Read))
{
fs.Write(buffer, 0, buffer.Length);
fs.Flush();
}

However, I am not being able to figure out how to export multiple articles into one single PDF document. Any help would be highly appreciated.

Thanks!

Zip Folders with Subfolders

Is there any way to zip a folder with all sub-folders included?

I can go through each subdirectory and zip its contents - but it doesn't keep the directory structure, and results in all files (from each sub folder) in the one directory

Any help appreciated

PdfDocumentSource can't load the document

Hello everybody

I have a problem with pdf file loading into PdfDocumentSource.

In the OnException handler I have next information:
Value cannot be null.
Parameter name: Pages

at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider.Import()
at Telerik.Windows.Documents.Fixed.PdfDocumentSource.CreateDocumentFromStreamOverride(Stream stream, FormatProviderSettings settings)
at Telerik.Windows.Documents.Fixed.FixedDocumentStreamSource.CreateDocumentFromStream(Stream stream, FormatProviderSettings settings)

This file is a scan of a document and has one page. I can open it in PDF readers.
Unfortunately I can't attach the file because it's confidential (and I don't have such problem with any other file).

Here is it's header and ending:
