Hello community.

I would like to make a save button only visible if the content of a text input box differs from a text in a label.

To the background:
I have this screen.

If I click on the pen, a text input box appears below which takes the text from the label 1: 1 above. (Next screen)

Now I can change this text in the textbox. And only when you have changed this text, the save button should appear.

How do I do it?

Best regards
RoScha

Hey @RoScha
the "OnChange" is only triggered after you clicked outside the box like you can make a lot of changes and Power Apps only checks it once. You are correct, you should use an if statement.
You can combine these in your Save buttons "Visible" Property like:
If(varVisible && Label1.Text <> TextInput1.Text,true,false)
So varVisible must be true and Label1.Text <> (not equal) TextInput1.Text then the button is visible otherwise, it is hidden.

@MarvinBangert
OK. I tried it and asked another question about it:
So it is not possible to check whether the text has changed or not while I am writing in the text box. Correct? I always have to click outside the text box to make the savebut visible.

And I have another question. I changed the text back to the original text in the text box and would have thought that the save button would then be invisible again. But he doesn't.
I suspect I have to add an if-then formula to the "Visible" property of the save button, right?

Re: Visibility of the save button depending on

Hey @RoScha

there is a property called "OnChange" for the textbox. You could use the function "Set(varVisible,true)" and add the variable "varVisible" to your buttons "Visible" property. The if the text in your textboxed is changed (and you clicked outside the box) the button would appear.

Hope this will help you!
