Reset datacard values when Combobox value is changed

Posted on by FranciscoSaba

Hello,

I'm trying to create a formula where DataCard values will reset when the selection in a ComboBox is changed.

Currently, I have a ResetControl = True on all of the DataCard values, for when the Form is submitted, it would reset the values:

In the Edit Form OnSuccess property: Set(ResetControl,true);Set(ResetControl,false)

In the Datacard value Reset property: ResetControl = true

I found a solution by adding this (below) formula to the OnChange property of the ComboBox. Still, it is not working with the ResetControl formula I already had in the Reset property.

ComboBox OnChange formula: UpdateContext({ resetVar: true }); UpdateContext({ resetVar: false })
Error on the Reset property for the DataCard values: ResetControl=true; resetVar

How can I make this work?

Hi @FranciscoSaba ,

Since the Reset property is declarative, you can't chain formulas. Instead you have to use logic operators:

ResetControl || resetVar

*Also you don't need to use "= true" since the value of ResetControl is a boolean in itself and will be accepted as such.

hi @FranciscoSaba,
maybe try to use
ComboBox.OnChange =
Reset(DataCardValue1) ; Reset(DataCardValue2);...;Reset(DataCardValueX)
