Microsoft - Please enable an option to set a Text Input in Power Apps to default to UPPER case

(1) ShareShare

Posted on by RhysWilliams 27

I've seen a few solutions on the internet, but nothing to solve the exact problem.

 

I have a Power App where one of the Text Inputs is to enter the Registration Mark of a vehicle (Number plate / Licence plate etc depending on your location).

I want this to show in upper case as the user types.

 

I know I can set a variable to change the input text to Upper OnChange but it still shows as lower case until the input is typed.

I know I can put text label below the input and set the visibility of the Text Input to false but then you cannot see the cursor for the Text Input.

 

Is there a solution out there?

 

Microsoft - why isn't this an option for the Text Input properties? Can be done relatively easily in JavaScript or HTML.

    Hi,
     
    You have to configure it with trigger output property to 'Key press' on the TextInputCanvas (modern one, not classic). Here it is:

     
    To make sure you reset value on screen visible, you set variable to null on the 'OnVisible' property of the screen:

    Then, you set a variable on the property 'OnChange' of the text input:

     
    You set Value property to:

     
    And it should works!
     
     
    I hope it helps!
