How to add a custom uploading filename max length validator to the Upload control?

[Nuttachai]

Hi,

I want to check the uploading filename max length, I could achieve this by checking the uploading filename in the UploadEvent and alert the error message, but I wish to show it in the Upload control like default style (See attached image).

How could I achieve this?


Thanks,

Hello,

Currently the Upload displays the gray warning text only when the file fails any of the built in restrictions (file type, min file size, max file size).

https://www.telerik.com/kendo-angular-ui/components/uploads/upload/restrictions/#toc-types-of-file-restrictions

In the current scenario we could indeed validate the file name length in the appropriate event handlers, however the warning text should be displayed using another approach e.g. dialog, template etc.
