Check if you have implemented the upload as per the documentation. Also check the network tab of your browser to trace the network request to the upload endpoint.
So, i've implemented the UpLoad controller following your documentation.
I don't understand why WebRootPath = null
If I do understand the definition of The web root path is the absolute path to the directory that contains the web-servable application content files. So wwwroot repository, right?
Thanks to the link.
I surprised that I've to create repository wwwroot in app.server wheras I've already wwwroot in my app.client.
Now It's ok the file is uploaded in app.server.wwwroot
Last Question : is it possible to download the xls or pdf file via RadzenHtmlEditor as an attachment file?
