[Patch] - printpreviewdialog prevent pdf print?

[The GridLock]

Hi,

If I use these lines then the dialog box appears and I see them, but after dialog hide, pdfviewer is not printed. I get a blank file..

if I delete them (using..end using). Everything will work! but i don't have preview mode.

Using printdialog As PrintPreviewDialog = New PrintPreviewDialog()

            printdialog.Document = pdfviewer.PrintDocument

            printdialog.ShowDialog() 

End Using

pdfviewer.Print(False)

How can i fix this?

Thanks you!

Advanced approach – use only if you have specific needs and can directly replace existing assemblies for your build environment
Please find the patch assemblies alone from below location:
http://syncfusion.com/Installs/support/patch/18.1.0.42/1174432/F154757/SyncfusionPatch_18.1.0.42_1174432_6242020073052178_F154757.zip

Assembly Version: 18.1.0.42
Installation Directions :
This patch should replace the files “Syncfusion.Pdf.Base,Syncfusion.PdfViewer.Windows” under the following folder.

Eg : $system drive:\Program Files\Syncfusion\Essential Studio\9.3.0.61\precompiledassemblies\9.3.0.61\4.0

To automatically run the Assembly Manager, please check the Run assembly manager checkbox option while installing the patch. If this option is unchecked, the patch will replace the assemblies in precompiled assemblies’ folder only. Then, you will have to manually copy and paste them to the preferred location or you will have to run the Syncfusion Assembly Manager application (available from the Syncfusion Dashboard, installed as a shortcut in the Application menu) to re-install assemblies.

Hi Uthandaraja ,

I think your attachment size is too big for the patch.

[Uthandaraja Selva Sundara Kani]

Hi Khanh, 

 

Usually we create patch files compatible for all the .NET frameworks (2.0, 3.5, 4.0, 4.5, 4.5.1 and 4.6) and .NET core 3.0. So that the size of the patch file is more due to the size of the PDF viewer assembly in 18.1.0.42 version. However, the patch file size can be reduced if we create a patch for specific .NET frameworks.  

 

If you need a patch with lesser file size, kindly let us know the .NET frameworks in which you need the patch. We will create a patch file for those specific .NET frameworks and provide you.
