PowerApps Rule - Set a fields value

[Jon2787]

Hi, I’m looking to replicate some InfoPath rules on PowerApps and hoping someone can please help.

To start with, I’ve built a form in PowerApps that’s linked to a SharePoint list and I’m looking to set a fields value based on another fields value.

For example, if Checkbox 1 or Checkbox 2 are ticked, I would like to populate another fields value, Text Box 1 for example, with a 1.

Also, if Checkbox 1 and Checkbox 2 are then later unticked, I would want this to clear the 1 value from Text Box 1.

This was easy enough to do with InfoPath Rules but can’t seem to work this out on PowerApps.

Any help would be great.

Thanks

Hi @Jon2787 ,

Well the simplest way to achieve this is to assign a value '1' to variable on OnCheck Property of Checkbox 1 & Checkbox 2  and use that variable in textbox field..and reset that value on OnUncheck Property

Checkbox 1/Checkbox 2 OnCheck Property : Set(varTextboxValue, 1)
Label Text Property: $"{varTextboxValue}"
Checkbox 1/Checkbox 2 OnUncheck Property: Set(varTextboxValue, Blank())

Now if you are not going to use this 'varTextboxValue' on another screen then use context variable instead..here is how you can achieve this

Checkbox 1/Checkbox 2 OnCheck Property : UpdateContext({locVarTextboxValue : 1})
Label Text Property: $"{locVarTextboxValue}"
Checkbox 1/Checkbox 2 OnUncheck Property: UpdateContext({locVarTextboxValue : Blank()})

Quick Tip: If variable values are required across screens, use global variable using Set function. But if they are used in same screen, use context variable using UpdateContext method.
