Toggle checkboxes (2 sets)

[sirch2020]

Hi guys, I have two checkbox in 2 columns that will act like a radio button

Example:

column 1        column 2

CboxOne         CboxTwo

So, if CboxOne is tick or check. CboxTwo will be unchecked.

Likewise, if CboxTwo is check, Cboxone will be unchecked.

Basically, each checkbox has a group of checkboxes that will appear only if either CboxOne or CboxTwo is ticked.

Any ideas on how to do this? Thank you.

Hi @sirch2020 ,

Put this on both the OnCheck and OnUncheck of both checkboxes

UpdateContext({vCheck:!vCheck})

On the Default of one box put

vCheck

and on the other 

!vCheck

You will find that they will "toggle" on and off if you change either.

Hey @sirch2020 ,

Lets say you have 4 checkbox One, two, three & four.

I would recommend you to take two global variables varCheckBoxThree & varCheckBoxFour.

(These are two different checkboxes that will become visible & invisible based upon CheckboxOne & CheckboxTwo input respectively. If checboxOne is checked CheckboxThree will be visible & if unchecked CheckboxThree will be unvisible. Similarly, If checboxTwo is checked CheckboxFour will be visible & if unchecked CheckboxFour will be unvisible).

Step - 1: Set them both 'false' OnApp Start functionality.

Syntax: Set(varCheckBoxThreeVisibility, false) Set(varCheckBoxFourVisibility, false)

Step - 2: Set the visible property of CheckboxThree and CheckboxFour.

Syntax:

For CheckBoxThree use varCheckBoxThreeVisibility

For CheckBoxFour use varCheckBoxFourVisibility

Step - 3: Set the Oncheck & OnUncheck property for CheckBoxOne

Syntax:

For OnCheck use: Set(varCheckBoxThreeVisibility, True); Set(varCheckBoxFourVisibility, false); Reset(CheckBoxTwo)

For OnUnCheck use: Set(varCheckBoxThreeVisibility, false);

Step - 4: Set the Oncheck & OnUncheck property for CheckBoxTwo

Syntax:

For OnCheck use: Set(varCheckBoxThreeVisibility, false); Set(varCheckBoxFourVisibility, True); Reset(CheckBoxOne)

For OnUnCheck use: Set(varCheckBoxFourVisibility, False);

Now, test your case.

I hope this simplifies your query if any more question let me know.

Warmly

@WarrenBelz sorry for being a noob on this, the default that you mentioned is it on the "advance" tab with the word 'default'? How do I set the default? Thank you.

[WarrenBelz]

@sirch2020 ,

Select the Item and then Default for the drop-down at top left., then type in the value in the box just to the right of this.

You can also set the OnCheck and OnUncheck here.

I actually did change  the default with the method you provided, but I got an error.

Error is: Name isn't valid. This identifier isn't recognized.

What I did is I change the name of the Checkbox to vCheck and the other to !vCheck and it works fine.

I am just using a Checkbox on a screen display no Gallery, no form or whatsoever, but anyway it works with what @WarrenBelz  provided as a solution.

I am still unclear why changing the defaults will result to an error, any ideas guys?  Thanks.

@sirch2020 ,

You may have done it the other way around and referred to the Variable before you put any code in to set it.

Anyway, glad it now works for you.

[sirch2020]

@WarrenBelz , Thanks you could be right, because if we put the variable without any reference then yes there will be an error. Ok got it now, Cheers!
