How To - TextInput.OnChange without pressing ENTER key

Hi all,

Anyone would have an idea of how to trigger the OnChange event of a TextInput control wihtout pressing the ENTER key but by just modifying its content.

I want to use this TextInput control as a filter for a gallery and I want the gallery to filter as the user types characters in the text input control (wihtout having to press the ENTER key).

If the Items property of your gallery references the content of the text input control directly, then it will be filtered based on when the user is typing on it. For example, if you have your gallery Items property set to

Filter(MyDataSource, StartsWith(MyColumn, TextInput1.Text))

then you should achieve what you want.

Hope this helps!

Hi @CarlosFigueira,

Yes of course, I know this is possible. But in some cases, we can't reference the label text value directly in the gallery datasource property.

My post here is rather to outline that some controls don't have their events triggered when they should be as their meaning is clearly specified in the PowerApps editor.

Here is the example of the checkbox control:

  • the Checked event of a checkbox control is described as is: Behavior run when the visual is checked
  • the event IS triggered when clicked -> OK
  • but if you check it through another control (say, a button using a variable), then the event IS NOT triggered even though IT IS checked!

I'm having a hard time finding some sense in this behavior... What's your (or others) opinion on this ?
