I create a PDF with Syncfusion PDF tools and I use PdfGrid multiple times and then add it to the page. I set the styles of the cells and rows have no border:
public PdfPen noPen = new PdfPen(PdfBrushes.Transparent, 0.5f);
This it comes out perfect in Adobe arobat web viewer, or regular viewer, but I get gridlines everywhere. What's going on?
