Appian Community and Appian Academy are being upgraded. As a part of the upgrade, Appian Community is currently in read-only mode, and user registration is disabled until August 3. We apologize for any inconvenience this may cause, but a more secure, stable, and performant Community experience is coming soon!
The new Appian Community launches August 3, followed by Appian Academy on August 7. During the migration, Appian Community Edition, Appian Academy, Documentation, Certifications, Instructor-led Customer Training, Partner Sales Training & Accreditation, and Forum (for Appian Partners and Customers only) will remain available.
I want to perform this validation after clicking on submit button.

There are many examples in the documentation:

Hi , I already added the validation as like document but I want to show the validation message through submit button.
Can I set the validation condition on submit button?
primaryButtons: { a!buttonWidget( label: "Submit", submit: true, style: "PRIMARY", loadingIndicator: true, validate: { } ) },
What do you mean with "validation message through submit button"?
And no, the file validation only works inside the file upload field. There are some unsupported dirty hacks to do this in a different way, but I do NOT recommend this.
Okay
