Do checkboxes have to be connected to a field in a datasource or can it function independently setting a variable to true or false?

Hi,

Do checkboxes have to be connected to a field in a datasource or can it function independently setting a variable to true or false?

Thanks a lot!

Regards,

Hi Daniel,

A checkbox can either update a field in the data source as you mention, or you could use the OnCheck, OnUncheck and OnSelect properties to update a local variable to true/false

For example
Set OnCheck -

UpdateContext({LocalVar: true})

Set OnUncheck - 
UpdateContext({LocalVar: false})

Thanks

Just as a follow on - You can simply refer to a checkbox to determine its value.  You don't need to use consuming variables to determine a checkbox value.

ex.  Checkbox1.Value  will be either true or false when you reference it in your app.  So, for example, if you have a TextInput and a Checkbox1 and you set the Visible of the TextInput to : Checkbox1.Value then the TextInput would only be visible when the checkbox is checked.

I hope this is helpful for you.
