Grouping by column does not work correctly when exporting to pdf

[Régis]

When I export the grouped grid to by columns in pdf, in pdf the groupings that have a lot of data split and generate several equal smaller groupings, when the right thing would be that the groupings remain independent of the amount of data.

Hi Regis,

Thank you for sharing the two screenshots along with the information on the PDF export.

Indeed, it is rather expected as when the grid is configured to export all pages, some groups are split across 2 or more pages. Therefore, when a group continues on the next page, its group header is repeated at the top. Since the grid exports what it "sees", the same group header is exported multiple times as well.

The only alternative that you could undertake is to handle the PDF export on your own. You should request all of the data of the grid and load it in a single page - this ensures that there will be not group split across multiple pages. After that, export the content to PDF, apply custom page breaks and after the export, return the old page size of the grid so that it becomes pageable once again. 

You could make use of our Drawing API for the PDF export, you could find more information and examples here:

I hope you find this helpful.

 

Kind regards,
