How to keep an Image in the Spreadsheet Header?
currently in the RadSpreadDocuments.HeaderFooterSettings only it supports text in the Page Header but want to display the Image in the Header.
Can anyone know how to keep the image in the Header of the excel workbook?


I have a word doc that i created using RadFlowDocument and i want to convert this to a pdf. i have tried couple of ways and it never worked.
'Exporting the Rad Document to Word Document
Using output As Stream = File.OpenWrite(directoryPath + "FlexFab.docx")
Dim provider As DocxFormatProvider = New DocxFormatProvider()
provider.Export(document, output)
End Using
'Convert word to PDF
Dim fileFormatProvider As IFormatProvider(Of RadFlowDocument) = New DocxFormatProvider()
Using input As FileStream = New FileStream(filePath, FileMode.Open)
document = fileFormatProvider.Import(input)
End Using
fileFormatProvider = New PdfFormatProvider()
Using output2 As Stream = New FileStream(directoryPath + "FlexFab.pdf", FileMode.OpenOrCreate)
fileFormatProvider.Export(document, output2)
End Using
The Error that i am getting is :
Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider' to type 'Telerik.Windows.Documents.Common.FormatProviders.IFormatProvider`1[Telerik.Windows.Documents.Flow.Model.RadFlowDocument]'.
I also tried the below method and that dosent work either, is there a way i can achieve this.
Dim document As RadFlowDocument = CreateRadFlowDocument
Dim provider Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
Dim fixedDocument As RadFixedDocument = provider.ExportToFixedDocument(document);
I am having trouble positioning text using text fragment. I'm not sure if its a scaling issue during import or what
Below is an extract that failes
I created a PDF completely gray with a black box starting at 100x100 pixels from the top left corner (https://www.pastefile.com/sjKGiJ)
The Original PDF was created by printing a blank page from work through adobe acrobat (for sizing) and then edited in illustrator to add the image.
Via the processor
The file is the imported using PdfStreamWriter and result written to a memory stream
The memorystream is the imported using RadFixedDocument and then text is added at 100x100 position.
Result is written to a file
Resulting file (https://www.pastefile.com/4HZwvR)
The text does not appear at 100x100 but at at ~ 74x70ish
the text font is not Helvetica but Arial
the font size is not 10pt but 5.63 pt
Code below (result is test4.pdf)

Hi,
We have a threaded service where we export excel documents to PDF documents (using Telerik.Windows.Documents.Spreadsheet.FormatProviders.Pdf.PdfFormatProvider.Export) and then merge the PDF with other PDF documents (using Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider.Import and RadFixedDocument.Merge). We make sure to dispose the Workbook of the excel document and the MemoryStream from exporting to PDF.
After some time we start getting the following error, until we restart the service.
One or more errors occurred. at System.Threading.Tasks.Task.WaitAll(Task[] tasks, Int32 millisecondsTimeout, CancellationToken cancellationToken) at Telerik.Windows.Documents.Utilities.TasksHelper.DoAsync(Action[] actions) at Telerik.Windows.Documents.Spreadsheet.Layout.RadWorksheetLayout.CalculateCellContentSizes(List`1 cellsToCalculateContentSize, CellProperties[] cellsFontProperties) at Telerik.Windows.Documents.Spreadsheet.Layout.RadWorksheetLayout.UpdateCellContentSizesCache() at Telerik.Windows.Documents.Spreadsheet.Layout.RadWorksheetLayout.Measure() at Telerik.Windows.Documents.Spreadsheet.Model.Workbook.UpdateWorksheetLayout(RadWorksheetLayout worksheetLayout, Worksheet worksheet, Boolean isForPrinting) at Telerik.Windows.Documents.Spreadsheet.Model.Shapes.ShapeCollection.GetTopLeftPoint() at Telerik.Windows.Documents.Spreadsheet.Model.Shapes.ShapeCollection.GetTopLeftCellIndex() at Telerik.Windows.Documents.Spreadsheet.Model.Shapes.ShapeCollection.RecalculateUsedCellRange() at Telerik.Windows.Documents.Spreadsheet.Model.Worksheet.get_TotalUsedCellRange() at Telerik.Windows.Documents.Spreadsheet.Layout.PageLayout.AddPages(Worksheet worksheet, Boolean ignorePrintArea) at Telerik.Windows.Documents.Spreadsheet.Layout.PageLayout.PreparePages(Workbook workbook, Boolean ignorePrintArea) at Telerik.Windows.Documents.Spreadsheet.FormatProviders.Pdf.PdfFormatProvider.ExportOverride(Workbook workbook, Stream output) ... ...

Any help on why this happens and how we can fix it would be appreciated.

I am trying to export my document but I am getting the error attached to the thread.
I can fix this by going into the properties of the document and checking the unblock box. Is there a way to do this in the export to be able to just open the document without having to go into its properties? I get the same error on the demo page for generating word documents https://demos.telerik.com/aspnet-ajax/wordsprocessing/generate-documents/defaultcs.aspx
Here is my code for export
RadFlowDocument document = report.GenerateDoc();
DocxFormatProvider provider = new DocxFormatProvider();
MemoryStream ms = new MemoryStream();
provider.Export(document, ms);
byte[] byteArray = ms.ToArray();
ms.Dispose();
return File(byteArray, "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "AAR.docx");

Hello, tell me please, can I do such a thing as merge/group cells in table with the same values when I export datatable from SQL base to word document
