问题 I have created a sample app where I have a grouped ListView and while scrolling through the listview I want to get the top visible group in the UI (first visible group). But when I keep scrolling on a touch based device, it starts showing the next group (next to the top visible group) for as long as I keep my finger on the device.

问题 I created a simple web app and a simple UWP app. In the web app, I've added a link to my uwp app. But after clicking on the link, the error comes " Error in parsing the app package. ". The . appxbundle is reachable, because if I remove ms-appinstaller:?source= from url, the downloading starts. Also, I've configured web app for MIME types. The package seems to be valid, because if I double click on downloaded file, the installation completes. Here some code samples: Web.config: <system

问题 I'm suffering from a file access problem. The main problem is I can't write a ZipFile in a folder which is acquired by the Folder Picker. While I've been working on this project, until I encountered this ZipFile problem, I did lots of jobs associated with creating files, with deleting files, with creating folders in that folder. It doesn't seem to matter for this problem. As the file-access documentation says, I have access permission on a folder which is chosen by the user when using the
