File Upload: Overwrite file


I'm using Blazor Webassembly with .Net6 (6.0.9) and Syncfusion 20.3.49.

I use the File Upload component with a remote URL and AllowMultipleFile=false.

I load a first file and it works fine. Then, I load a second file (to overwrite the first one) and the loading is “blocked”.

Why doesn't overwrite work? Is this feature available and how to implement it?

I attached an example project with a video.

Thanks for your help.

Best regards.

Hi François,

We have validated the shared sample on our end. In your scenario, you are trying to upload a single file at a time. So, We suggest you remove the SequentialUpload property or set SequentialUpload as false to resolve the reported issue on your end. When we upload multiple files (AllowMultiple = true) at the same time and If the SequentialUpload property is enabled, the file upload component performs the upload one after the other.

I set  SequentialUpload as false and it works as expected.

Thanks Udhaya Kumar.
