I would like to know how to prevent form submission when the kendo upload has a validation error. I know I can disable the submit button, but I would prefer when the button is clicked to run a validation check, if there is validation, return false on something similar.

Hi Benjamin,

You can validate the Kendo UI Upload component on form submit by using the Kendo UI Validator. To validate whether a file is selected and that the selected file has the correct extension, create a custom rule for the Validator.

Please check out the following example demonstrating this in a runnable demo:

Please let me know if you have any questions.
