Hello I have implemented the step by step procedure asked. But getting blank data.

HI!!!
i have opened open rdlc report with asp.net web api in custome web view successfully you teach but now i want to downlaod this opened file in pdf in mobile storage.Thanks

Hello good sir!
I'm new to xamarin and I have to finish an important project, how can I pass a path to de view instead of a url. I already managed the download of images to the desired folder, but i'm having trouble working with pdf files. I'm saving the downloaded pdf inside a folder using the FileSystem API and it seems to work, now I just need to be able to view it inside the app itself.
Also, is there a way I could pass the path to the downloads folder from the phone itself, since I managed to download pdf file to there as well.
Thanks in advance for any and all help with this issue, Greeting from Chile!

Hello,

I just tried the sample from GitHub, and updated all Nuget packages.
for IOS, Xamarin forms is now 4.8.0.164

when I try to run it on an iPad, the app crash with that error :
"Object reference not set to an instance of an object"

Hi Gerald!! I'm new on xamarin and i having hard times trying to make it read local files only!! I was trying to reach you on your site post but the comments were disabled!! Ty for the amazing tutorial

Hey,

the pdf.js dont can handle the "pinch-to-zoom"-Action.
You can fake this, with this javascript in the viewer.html, but you can only pinch-to-zoom, but not swipe left/right/up/down.
It's on Android / iOS.

Do you have any idea how to handle a pinch to zoom or generally touch gestures?

<script> let pinchZoomEnabled = false; function enablePinchZoom(pdfViewer) { let startX = 0, startY = 0; let initialPinchDistance = 0; let pinchScale = 1; const viewer = document.getElementById("viewer"); const container = document.getElementById("viewerContainer"); const reset = () => { startX = startY = initialPinchDistance = 0; pinchScale = 1; }; // Prevent native iOS page zoom document.addEventListener("touchmove", (e) => { if (e.scale !== 1) { e.preventDefault(); } }, { passive: false }); viewer.addEventListener("touchstart", (e) => { if (e.touches.length > 1) { startX = (e.touches[0].pageX + e.touches[1].pageX) / 2; startY = (e.touches[0].pageY + e.touches[1].pageY) / 2; initialPinchDistance = Math.hypot((e.touches[1].pageX - e.touches[0].pageX), (e.touches[1].pageY - e.touches[0].pageY)); } else { initialPinchDistance = 0; } }); viewer.addEventListener("touchmove", (e) => { if (initialPinchDistance <= 0 || e.touches.length < 2) { return; } const pinchDistance = Math.hypot((e.touches[1].pageX - e.touches[0].pageX), (e.touches[1].pageY - e.touches[0].pageY)); const originX = startX + container.scrollLeft; const originY = startY + container.scrollTop; pinchScale = pinchDistance / initialPinchDistance; viewer.style.transform = scale(${pinchScale}); viewer.style.transformOrigin = ${originX}px ${originY}px; }); viewer.addEventListener("touchend", (e) => { if (initialPinchDistance <= 0) { return; } viewer.style.transform = none; viewer.style.transformOrigin = unset; PDFViewerApplication.pdfViewer.currentScale *= pinchScale; const rect = container.getBoundingClientRect(); const dx = startX - rect.left; const dy = startY - rect.top; container.scrollLeft += dx * (pinchScale - 1); container.scrollTop += dy * (pinchScale - 1); reset(); }); } document.addEventListener('webviewerloaded', () => { if (!pinchZoomEnabled) { pinchZoomEnabled = true; enablePinchZoom(); } }); </script>
