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.
Is this still working for any of you, or was it in fact a 'bug' that's been changed? I tried to implement it to no avail.
The app I built at the time is still working with it, you might have me a bit worried that I don't want to change anything and break it though.
It’s very possible that I have a mistake on my end
I can confirm that it still works on 25th of April 2023.
The only thing that i had to add was a value to the "DefaultSelectedItems" Property of the Combobox (fe. First(PowerBIIntegration.Data).
It seems to me that "OnChange" Event of the Combobox Element is only triggered then!
