High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement asynchronous file uploads in ASP.NET Core with drag and drop support?▼

Asynchronous file uploads in ASP.NET Core use save and remove endpoints for non-blocking workflows, enabling drag-and-drop file selection and responsive progress feedback without page reloads.

What is the best way to validate file type and size during an ASP.NET Core file upload?▼

File validation in ASP.NET Core uploads enforces file type, file size, and duplicate file checks, providing guardrails that reject invalid files before the asynchronous save action reaches the server.

How do chunked uploads work for large files in an ASP.NET Core uploader?▼

Chunked uploads split large files into smaller segments sent sequentially to the server, allowing reliable transfer of large documents or media with progress tracking and automatic failure recovery.

Can I use Syncfusion EJ2 uploader with TagHelpers for folder uploads in ASP.NET Core?▼

Yes, TagHelper-based setup configures the Syncfusion EJ2 uploader for folder uploads, allowing entire directory structures to be selected and transferred asynchronously alongside standard file selection.

How do I handle upload progress and failure events in an ASP.NET Core file uploader?▼

Client-side event handling captures upload progress, failure responses, and security checks, allowing developers to display real-time status and trigger custom error handling during the file transfer workflow.
