Hello,

I am writing a very specific type of a report, which I have to control line height, dynamically generate content, and fill in a chart object. I'm currently doing this using OpenXML and Microsoft Word. When created, the end result is exported into PDF. This always seemed like overkill for me, and I would have preferred to use Telerik Reporting, except that Reporting doesn't let me set specific line heights.

In any case, I would like to try to dynamically build a web page of the report that I'm doing, which would be formatted exactly as I need it to be, and would also incorporate a RadChart. I would like to use either WordsProcessing or PDFProcessing to take the MemoryStream of this HTML page, and output it to PDF. Is this possible? I don't see any specific examples, although I see there is a conversion demo which can take HTML as input and create a PDF as output.

Thank you,
Alex

TelerikExport / Telerik.Windows.Documents.* Assemblies for .NET 3.5

Hey,

i recently needed to downgrade a project from .NET 4.0 to .NET 3.5

I used the SpreadExportRenderer in TelerikExport.dll for exporting a PivotGrid to Excel and now the code isn't working any more because of some missing dlls. It seems like the whole Telerik.Windows.Documents.* libraries and TelerikExport.dll is not availiable for .NET 3.5. They are located in the Bin40 folder, nut not in regular Bin (i have UI for WinForms Q2 2015 installied).

Is there something i am missing?

Thanks & Cheers,

Jens

Exporting rad combo boxes to PDF

I am trying to get a nice export of may page to PDF. I have several rad combo boxes that control the content of various areas of the page.

All the rad combo boxes are empty in the PDF - is there anyway around this? I was trying to use them a titles and I don't really want to have to repeat the selected value of the radcombobox in to a literal control next to each one - just so I can tell what I'm looking at in the PDF.

Thanks

raddocument and barcode control

I currently have the need to print a large amount of data from a silverlight app. The customer is using a third party pdf printer driver . unfortunately the amount of data is overwhelming that driver.

My first thought to combat this is to create my own pdf file as opposed to using the printer subsystem.

The only truly graphic element in the printout is barcodes. I use your barcode control. The rest is text/columnar data.

So the question :

Can I add your barcode control to the raddocument within a table/cell value so that it will render properly to the pdf file. If so how would I go about doing that.

Any Help would be appreciated

thanks

Using Freeze Panes

Hello,

In the document found on Telerik (http://docs.telerik.com/devtools/aspnet-ajax/controls/spreadprocessing/features/freeze-panes), it shows the ActiveWorksheet has a ViewState property, however I do not find that.

I am using the Workbook class found in the namespace Telerik.Windows.Documents.Spreadsheet.Model. It is my understanding that this is the correct Namespace / DLL(s) to use for processing spreadsheets.

Your help is appreciated,

Chris

Filter Rows of Imported Spreadsheet

We currently have a web application that allows the user to upload (utilizing the RadAsyncUpload control) files of different formats (csv,html,txt,xlsx) where the file stream (using the IWorkBookFormatProvider) is ultimately converted to a PDF and stored in a MSSQL database record. The purpose of this process is so that we can have varying formats of input data and a common datatype that can be displayed in the web application. The problem is that some of the csv, txt and xlsx files can have as many as 750,000 rows of data and for the purpose being discussed, we are only interested in the first 50 rows of the file. I can use RowSelection and Remove the unwanted rows on smaller files. However, this takes a long time to accomplished on large files. How can I:

Filter the worksheet rows so that I only get the first 50, or
Insert the first 50 rows from worksheet A to worksheet B.

Thanks,

Michael

No columns support, any idea how to use with columns?

Does anyone know how to handle columns? it appears that this is not a feature Telerik has added yet which i think is a Big oversight.

Most business related documents i have encountered all have columns which means when i tried to use Telerik's component they get all screwed up and not formatted right. Anyone have a suggestion how to address this short coming in code?

I sure hope Telerik realizes this is a big oversight and for Wordprocessing to be taken seriously they will need this.

In the mean time i either need to move to a different vendor component, or hopefully find a solution here...

any ideas?

Converting from ZipPackage to ZipArchive

I am trying to incorporate the latest build with ZipArchive rather than ZipPackage and am having difficulty getting it to create a valid zip file. Here is what works using the ZipPackage:

Dim VehicleID As Int32 = CInt(ddVehicleList.SelectedValue)

Dim memStream As New MemoryStream()

Dim Package As ZipPackage = ZipPackage.Create(memStream)

If VehicleID <> 0 Then

Dim fileIndex As Int32 = 0

For Each lvItem As ListViewItem In lvImages.Items

Try

Dim cbSelected As CheckBox = lvItem.FindControl("cbSelected")

If cbSelected.Checked Then

fileIndex += 1

Dim url As String = cbSelected.Attributes("url")

Dim photo As ZipData.Photo = GetPhotoWithTagByURL(url, lvItem, fileIndex)

Dim stream As Stream = New MemoryStream(photo.Data)

Package.AddStream(stream, photo.Name)

End If

Catch ex As Exception

End Try

Next

Else

End If

SendZipToClient(memStream, Package

Private Sub SendZipToClient(memStream As MemoryStream, Package As ZipPackage)

Dim FileName As String = ddVehicleList.SelectedItem.Text.Trim.Replace(" ", "_")

Package.Close(False)

memStream.Position = 0

If memStream IsNot Nothing AndAlso memStream.Length > 0 Then

Response.Clear()

Response.AddHeader("content-disposition", "attachment; filename=" + FileName + "_images.zip")

Response.ContentType = "application/zip"

Response.BinaryWrite(memStream.ToArray())

Response.[End]()

End If

End Sub

This is what I have so far with ZipArchive (gives me an invalid zip file):

Dim VehicleID As Int32 = CInt(ddVehicleList.SelectedValue)

Dim memStream As New MemoryStream()

Dim Archive As New ZipArchive(memStream, ZipArchiveMode.Create, False, System.Text.Encoding.UTF8)

If VehicleID <> 0 Then

Dim fileIndex As Int32 = 0

For Each lvItem As ListViewItem In lvImages.Items

Try

Dim cbSelected As CheckBox = lvItem.FindControl("cbSelected")

If cbSelected.Checked Then

fileIndex += 1

Dim url As String = cbSelected.Attributes("url")

Dim photo As ZipData.Photo = GetPhotoWithTagByURL(url, lvItem, fileIndex)

Dim stream As Stream = New MemoryStream(photo.Data)

'Package.AddStream(stream, photo.Name)

Dim lAttachment As ZipArchiveEntry = Archive.CreateEntry(photo.Name)

Using lAttachmentStream = lAttachment.Open()

Using lStreamWriter = New StreamWriter(stream)

lStreamWriter.Flush()

End Using

lAttachment.Dispose()

End If

Catch ex As Exception

End Try

Next

Else

End If

SendZipToClient(memStream, Archive)

Private Sub SendZipToClient(memStream As MemoryStream, Package As ZipArchive)

Dim FileName As String = ddVehicleList.SelectedItem.Text.Trim.Replace(" ", "_")

'Package.Close(False)

memStream.Position = 0

If memStream IsNot Nothing AndAlso memStream.Length > 0 Then

Response.Clear()

Response.AddHeader("content-disposition", "attachment; filename=" + FileName + "_images.zip")

Response.ContentType = "application/zip"

Response.BinaryWrite(memStream.ToArray())

Response.[End]()

End If

End Sub

Can you please tell me what I am doing wrong?

Thanks.
