Catch changing input

[Tex628]

Hello! 

I'm developing a PowerApp based on PowerBI integration. 

I need to be able to catch whenever the value i'm getting changes. 

So when the input changes from one string to another, i need to automatically change the value of a variable. 

Is there anyone that could give me some advice on how to approach this?

You can for example use the OnChange of a Text input to set the variable:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/controls/properties-core

Set( nameofvariable, valueofvariable )

And set the DisplayMode of the Text input to View if the information is not input of a user, but simply displaying information.

That was my first thought as well but i couldnt get it to work. 

I set the Default of the Text input to:

Last([@PowerBIIntegration].Data).'Dimension'

Then the onChange to:

Set( name, value )

The value clearly changed but the onChange control did not set off and change the variable...
Any clues?

I know this is an old post, but since it hasn't been solved, I thought I'd share what I was able to do. It may be a bug in PowerApps, as I stumbled over this by accident, but a combo box OnChange() event is triggered by a change in PowerBIIntegration.Data change. I added a hidden one that set a few variables when it was changed and it's all working well now.
