Validation - minimum amount of characters

Hello,

In my app I have a sharepoint list field (multi text) that users need to fill and then send.

I would like to create a validation button, that would prevent going forward when field has less then 40 characters.

I tried to do it like that:

If(DataCardValue2.Text > 39; true; false);Notify("Minimum 40 characters";NotificationType.Error);Navigate(Screen3;Fade)

or 

If(DataCardValue2.Text(Count) > 39; true; false);Notify("Minimum 40 characters";NotificationType.Error);Navigate(Screen3;Fade)

but it spams with unexpected characters, invalid list of arguments.

I know that this DataCardValue2.Text(Count) is stupid, but that was my best effort 😉

Hi @Elitezone

You were close!

Here's how I would do that:

If( Len(DataCardValue2.Text) < 40; Notify("Minimum 40 characters"; NotificationType.Error); Navigate(Screen3;Fade) )

We are checking the Length of the Text, and if its less than 40 characters we notify that it must be minimum 40, otherwise we navigate! 🙂

Cheers,

Sancho
