Set property of another field when OnSubmit is performed

[FrostedFlake]

I want to change the "Text" property of a Textfield when i submit my form. How can i assign a value to a Textfield out of the OnSubmit property?

In C# i would just assign it like this:

Class.Text = "XYZ"

Thanks!

PowerApps uses values by reference not by assignment.  

I am not sure what the OnSubmit property is that you refer to.  I am assuming you mean the OnSuccess of your form.

If so, you can set a variable in your OnSuccess action.  Either a screen variable - UpdateContext({someVar:"SomeVal"}) or a global app variable - Set(someVar, "SameVal")

You can then set the Text property of your control (presumably a label) to someVar

I hope this is helpful for you.

To expand on @RandyHayes' response, you may be looking to change/set the Update property of the Data Card within the form.

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/working-with-cards#information-flowing-...

In a nutshell:

• Forms are built-in controls which allow to quickly/easily setup a data source and inputs (fields)
• For each field, power apps inserts a Data Card
  • The Data Card is locked by default
  • It has a few controls (based on data type), which are included with the Data Card
  • The Data Card itself has a few properties; including the Update property
    • This is what is actually sent to the DB when you SubmitForm

You can unlock the Data Card and update the individual controls, and the properties of the Data Card itself. In your example, you'd be looking to

1. Use @RandyHayes suggestion of a local variable
2. Set the Default field of the control, with that variable (this is what the Update property of the data card references)
3. OR set the Update property equal to the variable
