Problems with creating PDF file

[Bernhard Höhn]

With the following code I create a PDF document from a grouping control.
For orientation I have set Landscape.
Without header and footer this works.
If I want to work with header (pdfConverter.ShowHeader = true;) only portrait is created and the rest is cut off.
Also, the first page is an empty page (with header). Also between the pages one or more empty pages (with header only) are created.

What can I do?

Here my code:

private static string Caption = string.Empty;
        private static string formName = string.Empty;
        private static GridPDFConverter pdfConverter = null;

        public static void ReportToPDF(GridControlBase grdAnzeige, Form form, string caption, bool landscape = false)

            dlgSave.Filter = "PDF-Dokumente|*.pdf";
            dlgSave.AddExtension = true;
            dlgSave.DefaultExt = ".pdf"; // Default file extension
            dlgSave.Title = "Speichern als PDF-Datei";
            dlgSave.FileName = "Untitled";

            form.Invalidate();
            Application.DoEvents();

            if (dlgSave.ShowDialog() != DialogResult.Cancel)
            {
                form.Cursor = Cursors.WaitCursor;

                pdfConverter = new GridPDFConverter();
                PdfDocument pdfdoc = new PdfDocument();
                PdfLayoutFormat format = new PdfLayoutFormat();

Hi Bernhard, 

 

Thank you for your patience. 

 

We have tested the reported case that the pdf document have extra blank pages when it has ShowHeader as true and the documents are exported properly without adding any pages. So, we suspect that the issue might be occurred due to some other settings of GridGroupingControl or the product version. So, please refer to the below sample and let us know, if we missed anything from the sample to reproduce the issue. If the below sample reproduces the issue at your end, please confirm your product version which will be helpful for us to assist you further.

Hello,

i have updated to version 18.1460.0.52, but i have the same problem here too.
I made a small test project with the corresponding data.
I have attached this as a zip-file, as well as the generated PDF-file.

Hi Bernhard, 

 

Thank you for the update. 

 

We could reproduce the issue that the GridGroupingControl adds additional empty pages when exporting it to pdf at our end and forwarded the query to our development team for further validation and update you with proper details on 01^st July 2020. We appreciate your patience till then.

Hi Bernhard, 

 

Sorry for the inconvenience. 

 

The reported issue is reproduced in the provided sample alone and not in a simple sample. So, we are validating with properties and setting of grid which causes the issue at our end with high priority and we need some more time to validate further and update you with further details on 03^rd July 2020. 

 

We appreciate your patience till then.

Hi Bernhard, 

 

Thank you for your patience. 

 

We have analyzed the sample completely and the reported scenario that the new page is added in pdf document is occurred due to the column width of the parent columns are updated with some higher value than the width of GridGroupingControl. In pdf document, the columns widths are updated based on the grid’s column width. In order to overcome this use case, we would suggest that you to set the column width for parent table with some lower values. We have modified the samples as per your requirement and please make use of the modified sample.
