I am using a Kendo Grid component with a large variety of data set sizes, so I would like to use auto, but still make it multipage and have the PDF header and footer. I have this working with paperSize of A4 but when I set it to 'auto', then the header/footer templates do not show.

Is this a known issue? Currently using pdf-export 2.0.0, angular-grid 4.8.4

Hi Tylor,

Setting the paperSize to a value different than the default 'auto' is indeed required in order for the repeated table headers to function as expected.

Thank you for the reply.

Then about a feature request: if we could set a page size of [ "auto", "8in" ] and then the PDF export could size the width to fit, but still perform page breaks where needed. Is this something that is supported now, or something that might be possible in future?

Thank you,
Tyler

Hi Tyler,

Providing an array of values for the pagerSize option doesn't seem possible. However, could I ask you to elaborate a bit more on the suggested feature request so that we can discuss it with the dedicated developers and consider adding it to our public Feedback Portal. Thank you.

Thank you for the reply and the hope that we might be able to solve this somehow.

So the situation is as follows: we have a grid control that dynamically loads various data sets. It might be 3 columns, or it could be 15 columns. When we want to export to PDF, if there are many columns, it can be cut off on the right side when set to a defined page size. We can set to 'auto', but then we lose all page breaks - everything gets put on to one page.

My thought above was to be able to specify a paperSize of ["auto","8in"] similar to how we can specify an exact page size of ["20mm", "20mm"]. This would expand the paper width to fit the data, but still divide up the pages into constant heights and thus multiple pages. And this would also allow space for headers and footers.

An alternate approach might be to use a set paperSize like "A4" or "Letter" but have a scale option of "auto" which would size the grid/columns to fit the given width, and break on the given height. Again, with headers and footers available.

I hope that helps. Thank you very much for your time.

Hi Tyler,

Thank you for the provided additional details. We checked the suggestions with the developers but decided not to log a Feature Request due to the following limitations.

Using paperSize="auto" extends the PDF content per page according to the exported content size. Thus the size for the header and footer aren't included in the calculation.

The PDFExport doesn't know when to use one paperSize option over the other. Instead the required option should be set by the developer. You can compute the size of the PDF page according to the size of the exported content as demonstrated on this article:

https://www.telerik.com/kendo-angular-ui/components/drawing/pdf-output/dimensions-css-units/

Based on the size of the exported content you can determine what paperSize option to set.
