Resetting a label that has a variable

(0) ShareShare
ReportReport
Posted on by CPGDallas 97

I have a scanning app that uses a 'scanvalue' as the variable to receive the barcode scan.

OnScan set to Set(scanValue,BarcodeScanner2_1.Value)

Label (hidden) has Text value of 'scanValue'.

TextInput control has Default set to '(lbl_ScanValue.Text)'.

 

I have a ResetVar set for all fields with a OnSelect of UpdateContext({ResetVar: true}); UpdateContext({ResetVar: false}).

All fields have Reset set to ResetVar.

 

Working on getting the scanValue to reset when I press the Reset icon.

    OnSelect of Reset:

    Set(scanValue,Blank())

     

    PS: You don't need hidden label. You can directly reference variable value inside textbox

    Set your label text to : BarcodeScanner2_1.Value

    You don't need to use a variable for this.

    I hope this is helpful for you.

    I thought the hidden label might not be needed but after adding the BarcodeScanner2_1.Value to the text field the input remained.  (Next post)

    However, using the method in this post did the trick!

    Set(scanValue,Blank())

     

    Thank you!

    Are you resetting your barcode scanner control??  If you are, there is no need for the variables, or even the labels.

    I am. That's interesting and I'll explore that option.  But there was something about getting the value converted to text to either display or patch to a SQL DB.
