Make field visible depended on other field - Powerapps

Shouldn't it be:

If(Received.Value=false, false, true)

??

I don't think you need the 'Selected' option here and if you inclose the expected value of the toggle in double quotes it means you are expecting the output to be a string while the output of the toggle is actually a boolean. It outputs true or false, not "true" or "false".

Please correct me if I'm wrong.

Older question, new functionality. :) Just wanted to make sure this was on the thread now that it's rolling out: Rules capabilities to show/hide and other.

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.
