User-defined variables and arithmetic transformations.A few available comments denote areas that can be improved. You may want to refactor the code to fit your coding standards.The automatic upload is disabled because the resizing of images on the client is asynchronous.The Upload does not offer such a feature out of the box and the suggested workaround may have side effects or provoke issues, especially with a wider variety of images users can upload.Return an empty string to signify success. The current example is a rudimentary one. Implement the server validation before saving. Using (var fileStream = new FileStream(physicalPath, FileMode.Create)) Var physicalPath = Path.Combine(appRoot, "SavedFiles", fileName) or some other location on your hard drive. Commonly, you may want to use the wwwroot folder through WebRootPath For portability, this will be in the application folder.
Var fileName = Path.GetFileName(().Trim('"')) Only the file name is of interest here. Some browsers send file names with a full path. Var fileContent = ContentDispositionHeaderValue.Parse(file.ContentDisposition) Public async Task SaveAsync(IEnumerable files) Public ResizeFileController(IHostingEnvironment env) needed to get the application root path public class ResizeFileController : Controller The controller is expected only to save the file but you may also add server resizing logic to ensure that the file matches the project requirements. The following example demonstrates how to configure the controller. Replace the original files with the new files.ĭata.rawFile = new File(, data.name) Var files = $("#files").data("kendoUpload").getFiles() Note that the file size that is shown by the Upload will therefore be wrong. A timeout so you do not break the built-in features and throw errors. Once resizing is done, initiate an upload through the upload method so that the files reach the => ev.Select("fileSelectHandler")).When you have the resized blob, create a File from it and replace the data in the Kendo UI Upload with the new data (file and its size).Use a timetout to start the resizing logic and prevent errors with the built-in Upload logic.To achieve client-side resizing of images, use the and Image elements for fetching a blob that will be part of the POST data to the server. How can I resize the photos before they are uploaded to reduce the amount of time it takes to upload them? Is it possible to resize the photos by using JavaScript and the Upload? Solution I am using the Upload for uploading photos that were taken with a phone.
