file uploading not working

Hi Prabudevarajan, 

Greetings from Syncfusion support.


By default, we cannot save the file in WASM using FileStream. Please find the below GitHub issue links for your reference.

https://github.com/mono/mono/issues/19907
https://github.com/dotnet/aspnetcore/issues/12186

If you are using core hosted application then we suggest you to save the file by creating controller in the server end app. If you are using normal WASM application instead of core hosted, we suggest you to save the file by creating a web API controller and pass the FileStream to it from Uploader Change event. Please find the sample below.

Uploader Sample Link   : https://www.syncfusion.com/downloads/support/directtrac/157285/ze/Client_Blazor-1995006075 

WebAPI controller Link : https://www.syncfusion.com/downloads/support/directtrac/general/ze/Blazor_Upload_App-220743914 

If this does not meet your requirements,kindly provide the below details to validate this issue further.

1. Code snippet of control rendering and also associated configured APIs and its Callbacks  

2. Video which demonstrates the issue  

3. A simple sample which replicates the issue, if possible.

Jeyanth.
