Posted on by Community Power Pla...

Hello i have a qr scanner that scans different value. I want to be able to make a navigation to a next screen upon scan based on the value it scans.
So if the value its 5 then navigate to screen 5 or if value its 3 navigate to screen 3

Any idea ?

Hi @Anonymous!

I would create a hidden TextInput control, then have its default value set to

BarcodeScanner1.Value

Then I would have the OnChange property set to:

If( BarcodeScanner1.Value = 1, Navigate(ScreenName1, transition.none), BarcodeScanner1.Value = 2, Navigate(ScreenName2, transition.none), BarcodeScanner1.Value = 3, Navigate(ScreenName3, transition.none) )

Initially make the TextInput visible so that you can confirm the QR codes are returning the correct values,

Could you give that a try and let me know if that's helped?

Thanks!

my default value its this First(Match(scanValue;"JOBB:(.+)LAGERSTED:";MatchOptions.Contains).SubMatches).Value

Because i have to split the qr value, but it gives me the value 5 so thats correct, but failes on navigation

Hi,

You said if the value equalled, so I used code for a numeric value, if you are using the split text then change your numbers from 1 to "1" to make it equate against the text values.

Additionally, I can see your editor is using ; instead of a comma ,

Please try the following:

If( Self.Text = "1"; Navigate(ScreenName1; transition.none); Self.Text = "2"; Navigate(ScreenName2; transition.none); Self.Text = "3"; Navigate(ScreenName3; transition.none) )

Thanks,

Sancho

alrdy done this.

My default : First(Match(scanValue;"JOBB:(.+)LAGERSTED:";MatchOptions.Contains).SubMatches).Value

My onchange : If(TextInput2.Text = "5"; Navigate([@SKIFT]; ScreenTransition.None); TextInput2.Text = "5"; Navigate(REP; Transition.None))

TextInput2 are the textinput Field itself. I have tried With the barcodescanner1 aswell but nothing. I did read something about this being a bug from Windows side

Thanks, Yes, was able to confirm that OnChange from another source doesnt trigger it, only if you input the text.

A workaround would be to use a timer, set to 50ms repeat autostart, and have its OnTimerEnd have that code that was on the Onchange of the TextInput:

The buttons shown are only setting the value to 4 or 5, which is then picked up by the timer

With Repeat and AutoStart on, it will run continuously, then you just need to make it invisible and users will be none the wiser
