Changing a property with a button

I put a label on the app and decided to get familiar with PowerApps by doing some basic things. Mind you I am not a developer but did ask fellow Devs before coming here with no luck.

After putting a label on the screen, I then selected its "Fill" property and wrote the following formula.

If(Checkbox1!Value = true, RGBA(244, 115, 33, 1), RGBA(0, 0, 0, 0 ))

This works great.

Now, if I put a button on the screen and replace Checkbox1!Value to Button1!Pressed it does not work. Why? I want to be able to have users press buttons and things to change, is this not the expected behaviour?

Also, how can I change the button to use one of my images instead?

Thanks for your time.

Hi

Add a button, say the name remains as Button1. It Works for me.

If(Button1!Pressed, RGBA(244, 115, 33, 1), RGBA(0, 0, 0, 0 )).

Remember, you don't have to be Button1!Pressed = true. Your "Click or Press" action tells it "It is true when Pressed and False when released")

Does not work for me and a friend who also has access to the preview tried it and does not work for him either.

Do you have anything different? I'm on 2.0.320

HI

Apologize for that. As I was offline just now, I used Project Siena to confirm and it really worked.

I tried again on PoweApps now and yup, you are right, nothing changed!

Wish someone else can figure out why PowerApps can't.

Anyway, temporarily I advise to use Pressed Fill and Press Color (as in image) to change color when someone click on the Button with contents or even Label with contents. both work.

Try this on 2.0.340 (released last night):

1. On the Content tab, select Media, and then select Image.

2. Near the upper-right corner, select Browse, select the image that you want to use, and then selectOpen.

3. Press Esc to return to the default workspace.

4. Add an image control, set its Image property to the file that you just added, and set its OnSelectproperty to this formula:

If(BoxColor = "orange", UpdateContext({BoxColor:"white"}), UpdateContext({BoxColor:"orange"}))

5. Add a text box, and then set its Fill property to this formula:

If(BoxColor="white", RGBA(0,0,0,0), RGBA(244, 115, 33, 1))

Going to try it, but not sure I understand where the BoxColor property comes from?

Getting used to PowerApps and it's weird it works by doing a lot of If and a lot of update context to set variables and then using them.

I was expecting something a little more straight forward, I got a button and I want text.nameofproperty to change to x when I press it.

In any case will check it out and it helps me not use a button, seems to be like the Button is not meant to be used except for navigate to another screen or patch my datasource.

You can absolutely use a button instead of an image. I suggested the image only because you said: "Also, how can I change the button to use one of my images instead?"

To use a button, skip the first three steps, and change step 4 to:

4. Add a button, and set its OnSelect property to...

You use a context variable (which I named BoxColor, but you can specify your own name) because, for example, you can change the fill from white to orange when a user selects the button, but what should happen if the user selects the button again? Should the fill stay orange?

Does this topic help?
