I see this is online help:
https://www.telerik.com/kendo-angular-ui/components/uploads/upload/how-to/local-file-processing/
As of version 5.2.0 the Kendo UI Upload for Angular features a built-in FileSelect component. You could use this component instead of the approach suggested in the article below.
But I do not see an example of how to do this with fileselect?
Can you please provide an example or point me to the documentation that describes it in detail?
