Hi, I want generate Document with two Section, One Calculate widht Image and one Document from Db.
The Code:

 

RadDocument doc = new RadDocument();

Telerik.Windows.Documents.Model.Section section1 = new Telerik.Windows.Documents.Model.Section();
 

Telerik.Windows.Documents.Model.Paragraph paragraphImage = new Telerik.Windows.Documents.Model.Paragraph();

Stream stream = Application.GetResourceStream(new Uri(@"/AttiDirigenziali;component/Views/Immagini/Stemma.jpg", UriKind.RelativeOrAbsolute)).Stream;

 
Size size = new Size(226, 110);
 

ImageInline image1 = new ImageInline(stream, size, "jpg");
 

paragraphImage.Inlines.Add(image1);

section1.Paragraphs.Add(paragraphImage);

doc.Sections.Add(section1);
 

RadDocument docCorpo = null;

IDocumentFormatProvider provider = new DocxFormatProvider();

Stream s = new MemoryStream(e.Result); //e.result is Document from Db
 

docCorpo = provider.Import(s);

doc.Sections.Add(docCorpo.Sections.First());

 
IDocumentFormatProvider providerPdf = new DocxFormatProvider();

 
MemoryStream output = new MemoryStream();

providerPdf.Export(doc, output);

 

 

Error:
Impossibile eseguire il cast di oggetti di tipo 'Telerik.Windows.Documents.Model.ImageInline' sul tipo 'Telerik.Windows.Documents.Model.Span'.

Hi Luciano,

Unfortunately we were unable to reproduce the problem. It will be helpful if you send us a project that in which the issue is present so we can investigate the problem.

However, I would suggest a simpler solution for you task. You can use the InsertInline method of RadDocument class to insert the image at the beginning of the document. Here is a code snippet:

Stream ImageStream = Application.GetResourceStream(new Uri(@"/MSWordDemo;component/Images/smile.jpg", UriKind.RelativeOrAbsolute)).Stream;
ImageInline imageInline = new ImageInline(ImageStream, new Size(226, 110), "jpg");

docCorpo.InsertInline(imageInline);
docCorpo.InsertInline(new Span(FormattingSymbolLayoutBox.ENTER));

This will add the image in a separate paragraph.

I hope this is helpful. Please let us know if you need further assistance.

RadDocument doc = new RadDocument();

 

 

 

Stream ImageStream = Application.GetResourceStream(new Uri(@"/TestTelerikExportImage;component/Stemma.jpg", UriKind.RelativeOrAbsolute)).Stream;

 

 

 

ImageInline imageInline = new ImageInline(ImageStream, new Size(226, 110), "jpg");

 

doc.InsertInline(imageInline);

/// Error

 

I work on the fly with raddocument for generate document pdf with my wcf.


Thanks, Luciano

Hi Luciano,

Looking at your code, my only suggestion is to check if ImageStream isn't null by any chance, or if Stemma.jpg is an invalid image (may be other image format like bmp, png, or gif that was renamed to jpg). Without looking at the complete solution (not just code fragments), unfortunately, I can't give you any more clues.
Get back to us if you need further assistance, preferably with a sample solution which demonstrates your problem. You can open a support ticket where you will be able to attach a zipped version of your solution.

Best wishes,
Ivailo
