Hi,

I would like to export some excel files in a zip without writing on disk.

I have seen ZipLibrary example and I would like to adapt it with excel (if possible).

The idea is to do something like this in "OnClick" event for exemple (see code bellow)

Thanks in advance for your help

Do you have any sample code to set a form field with an image so that the image is centered in the form field but keeps it's aspect ratio without going outside the bounding box? Does the image need to be resized first to reduce filesize?

Thanks.

I am placing a image in a table cell and below the image I will be adding 1 to 3 lines of text.   I have it all working, but have 2 questions.

1.  I would like to center the image vertically in the table cell.

2. I want to single space the inserted text (paragraph) 

Below is my code:

 using (Stream firstImage = File.OpenRead(outputFileName))
                            {
                                var inImage = table1.Rows[x].Cells[y].Blocks.AddParagraph().Inlines.AddImageInline();

                                inImage.Image.Size = new System.Windows.Size(colWidth, colWidth);

                                inImage.Image.LockAspectRatio = true;
                                inImage.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(firstImage, "jpg");
                            }
                            table1.Rows[x].Cells[y].Blocks.AddParagraph().Inlines.AddRun(Path.GetFileNameWithoutExtension(h.fileName)); // filename

Hello,

I'm trying to work with Telerik PDF-Processing right now. But an issue appeared, that I have no clue how to solve.

In this current project, time is a very important aspect, so it's necessary for me to save milliseconds everywhere i can. So I logged the time for all of the Processes and, I don't know why, the first time, i use the methods, it needs more time, than the other later runs.

Here's a simple example out of this project:

 private List<RadFixedPage> GetAllAddingPages(List<string> pathList)
        {    
            List<RadFixedPage> AllPages = new List<RadFixedPage>();

            for (int i = 1; i < pathList.Count; i++)
            {
                RadFixedPage read = provider.Import(File.ReadAllBytes(pathList[i])).Pages[0];
                AllPages.Add(read);
            }
            return AllPages;
        }

The method's supposed to read the first pages of every document, that is filled in the "PathList." 

I've stopped the first run and it needed about 150-160ms to execute. The second run is all about 20ms. There are only 3 Files that've been loaded.

So i tested more..

If i only load a document, that has no Image inside, it needs about the same time on the first run. If afterwards a document is loaded with only an Image, it needs long time also (103ms). If I open 3 documents (Vectorgraphics, Images and Text) it needs the 150-160ms. 

Is this a known issue, or can somebody maybe help me with this?

This is only one example, where this problem appears. But if there is a solution for this one, i can maybe apply it to the other methods.

Best regards

Jakob

I have a table that has a variable number of columns (from 2 to 6)

I set preferredWidth  based on number of columns as follows:

 table1.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 100);

I am inserting images into each table cell, but I want specify the size of the image based on the cell width

How do I get the cell width?

var inImage = table1.Rows[x].Cells[y].Blocks.AddParagraph().Inlines.AddImageInline();
                        var cellWidth =??
                         inImage.Image.Size = new System.Windows.Size(cellWidth, cellWidth);

 Hi All,

Hello!
Faced an incomprehensible problem.
When trying to open a workbook, an exception is thrown:
ArgumentOutOfRangeException: Index and count must refer to a location within the string. (Parameter 'count')
At the same time, everything works fine on the working computer during development, there is no exception.
The problem pops up when placing a project on a hosting.

The library from Syncfusion in a similar environment opens the file normally on the hosting.

Library version 2020.3.1019
.net5 Server-side project

Attached a project to demonstrate some issues we're seeing that need resolving in order to use the component.

1. When using a font like Tahoma on a form field, the value no longer displays or contains garbled text.

2. Input file is 24KB, output is 2MB!

3. Rotated field lose their rotation after being flattened.

4. Simulate merging with other files, 100 times the file is now 150MB! It's as though it's not re-using the fonts, but keeps adding the same ones.

5. when merging, but not flattening, the form fields are all lost on pages after page 1.

Good day all.

I am developing an application using C# WinForms and Telerik 2020.1.218.40 that needs to take pre-filled PDF forms and display the page images as static documents. I have been able to read the PDFs and split the documents into individual pages, which when viewed using Microsoft Edge's PDF rendering, displays the forms with data, but when loaded into a RadPdfViewer, only displays the form image without any of the completed data.

Any help in displaying the form data is appreciated.

private static readonly string uploadPath = "H:\\TEMP\\DMSUpload\\";

string splitNameTemplate = Path.Combine(uploadPath, "SplitPage-{0}.pdf");

using (FileStream fs = new FileStream(uploadPath + "TEMP.PDF", FileMode.OpenOrCreate))
{
       RadFixedDocument document = new PdfFormatProvider().Import(fs);
       using (FileStream writeStream = new FileStream(uploadPath + "FOO.PDF", FileMode.OpenOrCreate))
       {
            PdfFormatProvider provider = new PdfFormatProvider();
            provider.Export(document, writeStream);
            using (PdfFileSource fileSource = new PdfFileSource(writeStream))
            {
                 for (int i = 0; i < fileSource.Pages.Length; i++)
                 {
                       using (PdfStreamWriter fileWriter = new PdfStreamWriter(File.OpenWrite(string.Format(splitNameTemplate, i + 1))))
                       {
                            PdfPageSource pageSource = fileSource.Pages[i];
                            fileWriter.WritePage(pageSource);
                       }
                 }
           }
      }
 }
 pdfViewer.LoadDocument(uploadPath + "SplitPage-1.pdf");
