The file selection popup on iOS does not always open next to the file select popup. This is possible to replicate on the main page for the angular upload component https://www.telerik.com/kendo-angular-ui/components/uploads/upload/ and the stackblitz as well without any modification
Screenshot shows that the photo library/choose files popup opens in a seemingly random spot after the user taps it.
Given a file is selected using the fileselect component
And one or more of the restrictions bound to the control are violated
The error message that is displayed should be configurable
For example, if the maxFileSize restriction has been set to 20mb and a file larger than that is selected, the control currently displays some error text to the user as follows: "File size too large". It would be beneficial if we could override this message so it (for example) could say "File size too large. The maximum file size is 20mb".
Currently, the title of the Select button says always "No file chosen". That is due to the input element being re-rendered with a new one each time a file is selected.
What could be done to set a custom title for the Select button is to set a "title" attribute to the kendo-fileselect tag.
The title could be further enhanced so that it is localizable.
