Description

The Telerik UI Upload for ASP.NET Core component supports file validation based on their size and extensions.

This demo example shows the AllowedExtensions configuration that accepts the listed types of file that are allowed for upload as an array of strings. The last example demonstrates the MaxFileSize() option which does not allow upload of files that exceed the set limit. In addition, there is also a MinFileSize() option which does not allow files that are less than the set minimum size.

Additional Apps

This Upload example is part of unique collection of hundreds of ASP.NET Core demos, with which you can see all Telerik ASP.NET Core components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for ASP.NET Core or ThemeBuilder.
