How to perform form validation when using custom input function?

Hi everyone, 

 

I recently asked a question on this forum regarding passing form data to a custom component.

In the above, the Calculate button is a custom component which has its onSelect and other behavior functions defined within the components section. To pass the values, I used an input custom function which makes use of Form.Updates. This works great! 

 

However, my question is, how do I validate the form using this approach? I require that the fields are not blank. 

 

Any suggestions on how I may implement this please? 

 

Thanks in advance!

A simple solution would be to make the component (calculate button) invisible until all fields are filled, like

 

Visible:

Len(TextInput1.Text)>0
&&
Len(TextInput2.Text)>0

etc for all fields you want to be mandatory and non-blank

 

Cheers,
