Click image hide another image

Hello

I'm quite new to powerapps so this might seem like a really silly question, but I have 2 screens called

Screen1

Screen2

in screen1 I have an image which is called "visualDemo" and in screen2 I have another image called "imgAction"

Both the visualDemo image and imgAction are set to visible, so they can be seen

What I want to do is use the "onSelect" field on "imgAction", so when it is clicked, the image "visualDemo" simply becomes invisible

I tried adding the following to the "onSelect" field in "imgAction" to

Set(visualDemo;false)

but that produced an error

Any ideas?

Thanks

Unless you are in a different country, then the it should be with a comma Set(visualDemo, false)

If you set VisualDemo false that creates a variable called VisualDemo. You then need to set the Visible property of the VisualDemo control to VisualDemo. Then when VisualDemo is set to false the VisualDemo control will disappear. But I recommend not using the same exact name for the control that you use for the variable.

Oh ok @Pstork1 thanks, so I set the name of the variable in the "Visible" property of the image

So could you explain, when I do this, the image seems to become hidden, how can you set the variable name in the "Visible" property of the image, but tell it to make the image visible upon load?

I tried

VisualDemo = true

but that didnt seem to work

Thanks

Add a Set(VisualDemo, true) in the onVisible property for the screen or the OnStart for the app. That will set the initial value of the variable to true. Let me explain what is happening. Power Apps is a declarative system so you can't manually change object properties at runtime. But you can change the value of variables. So you set the variables to the values you want to use and then set the properties to be equal to whatever the variable is.

@Pstork1 I just tried that, but for some reason the image remains hidden, am I doing something wrong?

By the way, for ease, I renamed "VisualDemo" to "GV"

Thanks in advance

What do you mean it remains hidden? Setting the variable to true should show the image until Image2 is clicked. After that it will stay hidden until you do something that sets the variable back to true. App.OnStart and Screen.OnVisible only run the first time they are encountered when starting the program. You would need something else to reset the variable to allow the image to appear again.
