In the documentation, The upload url is specified like this
<RadzenHtmlEditor UploadUrl="upload/image" />
I want to use a url from an external API.
I tried adding absolute url like this
<RadzenHtmlEditor UploadUrl="http://localhost:5000/upload/image" />
but this doesn't work.
Can you elaborate what "doesn't work" means? What is the error message you see in your browser's developer tools during upload? There is a chance your API does not allow CORS which is needed by the upload feature..
The upload dialog doesn't open.
This is the error message in the browser console
Unhandled exception rendering component: target.matches is not a function
This sounds unrelated. The matches function is used in two locations neither of which is the upload.
