Hi,

I have to buttons which can't be both in the same time positive.

I want that if one is true the other will be false, and the opposite.

I have tried to set the default value with:

If (DataCardValue10=true,false,true)

But I receive error.

Can someone help me please?

BTW I want to have the option for both to be false

(So the options are: 1. true, false 2. false, true 3. false, false)

Hi @moshem ,

Firstly, you cannot base them off each other or you will have a circular reference, so set a Variable on the OnChange of each = Radio 1

UpdateContext({varRadio1: !Self.Value})

and the other Radio 2

UpdateContext({varRadio2: !Self.Value})

and the Default of Radio1

varRadio2

and the Default of Radio2

varRadio1

make sure at Screen OnVisible to initiate the Variables

UpdateContext( { varRadio1: false, varRadio2: false } )

Thank you @WarrenBelz Now it is the opposite, but I need to have the option for false and false, and now if the user once chose true for one of the options he can't make both false again (it is false only in the default view)

1) false true - you have answered
2) true false - you have answerd
3) false false - which you have made as the defualt but a user can't go back to this option if he by mistake chose one of the other options

@moshem ,

Run the code I provided for Screen OnVisible - it will set both values to False

I have tried to uplaod a vid of the issue but it is an invalid file type here.

I'll put screen shots:
1) I have the code on screen:
2) Now one of them is always false:

3) Even when I press reset form it doesn't help:
4) I have tried to add a button with the code of both to false and it didn't help:

create two variables (var_radio1, var_radio2)
- set default value of radio button with these variables
- use 'OnSelect' function in Radio1 and paste:
Set(var_radio1,Self.Selected.Value);Set(var_radio2,If(Self.Selected.Value = "Yes","No","Yes"))
- use 'OnSelect' function in Radio2 and paste:
Set(var_radio2,Self.Selected.Value);Set(var_radio1,If(Self.Selected.Value = "Yes","No","Yes"))

Hi @moshem ,

I had a chance to test it this time - try the following (replace all of the first one) - and they are toggles, not Radio buttons and note the change to OnSelect from OnChange

Toggle1 OnSelect

UpdateContext( { varToggle1: !Self.Value, varReset: false } ); Reset(Toggle2)

Toggle2 OnSelect

UpdateContext( { varToggle2: !Self.Value, varReset: false } ); Reset(Toggle1)

Default of Toggle1

If( varReset, false, varToggle2 )

Default of Toggle2

If( varReset, false, varToggle1 )

Reset button and Screen OnVisible

UpdateContext( { varToggle1: false, varToggle2: false, varReset: true } ); Reset(Toggle1); Reset(Toggle2)

As below
