That is to slick, even though I picked a .doc file the upload button still shows but when I click it nothing happens. That will work, thank you guys for your help.

I think the point Stefan is trying to make is, what you describe is design and not requirement. As in, the fact that you can validate against a .csv file being uploaded, means the user will be unable to submit the form, regardless of whether the button is disabled - and thus the end result will be exactly the same.

They are asking for the submit button to stay disabled until a valid csv file is dropped into the upload box. So when a valid csv file is dropped in the upload box the button can be pressed, if no file picked yet disabled, if they pick a .docx keep it disabled until .csv file is picked...

Why do you "need" to do that? Is that a requirement? If yes, why?

The code you're trying to execute here is invalid in a few different ways.

find("CSV", a!fileUploadField(value: upper(document(ri!csvFile_txt, "extension"))))

And even if you did correct that to do what I assume you're trying to do, it's still unsupported functionality.

[quote userid="90333" url="~/discussions/f/user-interface/25309/file-upload-validate-extension-on-button-disabled"]The passed parameter(s) are of the wrong type. Received the type Text. [/quote]

This is because you're trying to pass in a "value" for the File Upload Field, but the "value" you're passing is text. The value for the File Upload Field must be document, not text.

I am using the validation feature on the upload file component, when you pick a file that is not a csv file it tells the user the file is invalid and to remove it and pick a csv file. But I need the submit button to stay disabled until they pick a csv file.

The best way to add a validation to your form is to use the validation feature of each input component. Is there a specific reason for not using that?
