Hi there,

I have several text input fields in my Canvas app that I don't want the user to be able to skip past when they are using the app.

I would like a message to display in red if they try to select the Next button (which has a Navigate to next page function on it) when the text input box is blank, and prevent them from moving on until this has been infilled.

Is there some code that I can copy and paste somewhere for this?

Thanks

Phil

Re: Error message to display if box empty

1.To display error message based on validation you can use this property on form. Just click on error message. Go to it's "Visible" property. And write your logic there.

2. If you want to prevent them from moving on untill there is some data. Go to "Next" button's "Visisble" property and write logic like. "If!(IsBalnk(Datacarad1) &&if(!IsBlank(Datacarda2),true,false))".
I can't give you the exact code before seeing all the details.

Re: Error message to display if box empty

Thanks for the suggestions.

The Next button is called "Icon3_7" and the text input field is called "DescInput_Inputs_1".

So I want it whereby, if DescInput_Inputs_1 is blank and the user clicks Icon3_7, a message displays saying "Please complete all required fields before continuing"...

Thanks

Phil

Go to " Icon3_7" Visible property. Write
If( !IsBlank(DescInput_Inputs_1),true,false).
Your button will not be visible on screen untill there is some data in "DescInput_Inputs_1".

To display message:
Go to required property of "DescInput_Inputs_1 ". Make it "true".
Then go to ErrorMessage of that card. And write whatever message you want to display.
