We have created a KB article where a possible approach to achieve image resizing before the upload is suggested. You can find it at https://www.telerik.com/support/kb/aspnet-ajax/upload-(async)/details/resize-images-client-side-with-html5-before-uploading-with-radasyncupload The article describes a straightforward way on how to change the uploaded image dimensions. You can further improve and modify the logic in the _uploadFile function to allow the user to define the new dimensions or use a tool to allow the users to modify the image.
The user should be able to determine by which criteria the validation failed (size or extension).
Hi Telerik Team, is it possible to implement the feature into the uploadmodule control , that you can open the uploaded files per Double-Click. We want to use the control to create offers and we want to give the users the option to upload files - that works wonderful. But the following editors of the offers don`t have the chance to open the "attached" files. Thank you very much. Best Regards, Jan Brandenburger
Hi, When we upload files using RadAsyncUpload control, will get the uploaded file along with the two images. 1. check image 2. cross image (to delete the uploaded file) my question is can we overwrite these images in our application.
Why not add a "basic mode" to radasyncupload? that saves the selected file(s) in the target folder as soon as the upload is complete without the need for an extra postback? Or facilitate a postback through a popup "upload complete" with an ok button? And a little feedback in general on the documentation nearly all the examples have all the bells and whistles active, which makes them hard to read for programmers with little experience like me. Why not have every control with a absolutely minimalistic example that only shows the core functionality?
