Convert a String (Text) value to a formula

[Romsteck]

Hi there,

It is possible to convert a Text value to a formula ?

I need to create a lot of fields in my PowerApps, so I made a list of them.

Now I need to configure the controls to edit my data in D365, but I can't link the good field with it..

Does someone has a solution ?

Don't hesitate to ask me for more details about my App if necessary 🙂

Thanks in advance !

Have a good Day !

What exactly do you mean? Text to formula as in you have a text field such as 

Collect(TestCollection,{Value:"Hello, World!"})

and you want to run that as code from text?

Hi again @EricLott ,

I have misunderstood what you said, sorry..

It's exactly what I mean 😉

My English is very bad 😅

So please do you have a solution ?

Thanks !

Could you please explain again what you're trying to do? Feel free to use your native language if you prefer. I'm sorry, but I just am not understanding your question.

You can add a Data Source from PowerApps, add a Form, and select your Fields, and then you can add fields without having to manually make any fields.

Hi @EricLott,

So in French :

Je dois créer un formulaire comportant 300 champs. Il y a 4 champs par section de formulaire.

Je dois également configurer des contrôle de manières customisée (Utilisations d'Option Sets).

J'ai donc essayé de créer une Collection contenant les champs, je crée un Item pour chaque Sous-Section, et j'ajoute les propriétés "Name", "Display Name" et "Subsection".

Malheureusement, je ne peux pas faire en sorte que mes champs se configure automatiquement car les propriétés "Name" et "Display Name" doivent être entrées en tant que code.

N'hésitez pas à me demander plus d'infos !

Thank you !

Best Regards,

Romain.

Hi @poweractivate,

This is the way I use to create my form, of course, but forms become very slow when there is too much fields.

Best Regards,

Romain.

Yes we understand what you are saying (maybe).

You want Runtime Evaluation in PowerApps. and you are asking how to do it.

You are looking for Eval like functionality in Javascript to use it for PowerApps.

So essentially you want an expression interpreter at runtime, something that can evaluate the text at run time and turn it into a Formula. 

@Romsteck  we believe this is not supported to evaluate the Formula from string, out of the box at this time.

You can try upvote the below submitted idea:

Eval() function 

You can also try looking into PowerApps Component Framework. However, we are not sure that even if you go so far as to develop a custom component, that you can force PowerApps to evaluate a string and turn it into a Formula at run time. 

Was this what you were asking about?
