Make field visible depended on other field - Powerapps

Hi,

In the OnVisible property of your screen, create a Context Variable and set it's value to false.

 UpdateContext({cVisible: false})

Then set the calandar controls Visible property to to the context variable, in this example that would be cVisible

On the check box control set the OnCheck property to update the Context variable

 UpdateContext({cVisible: true})

You can reset the context variable in the checkbox OnUnCheck property to reset as well

to get a toggle effect.

 UpdateContext({cVisible: false})

Hope this helps.
