Recently came across a requirement where the user expected the currency formatting at runtime. Power Apps does not inherently support any currency input for a text box. We currently have the input formats as Number and Text as represented below:

We need to keep the input text field format as Number to prevent the user from inserting non-numeric values in the said field. Now the question arises as how we can display formatting at runtime.

Option 1 : From the text box input , the event that we can capture is the OnChange , so while tabbing out the formatting is enabled and user can see the formatted value in the text box itself. For this we need to set a variable with the formatted value on the OnChange Event as shown:

Code :

Set( FormattedCurrency, Text( Value(txtUnitPrice.Text), "$#,##0.00", Language() ) )

We need to do one additional step, i.e set this Variable - FormattedCurrency defined above as the Default attribute of the TextBox input.

This enables near runtime formatting, with the formatting enabled on the tab event.

Options 2 : If the user is expecting formatting while typing itself and not willing to wait for the tabbed event, we can add a label adjacent the text box and set its Text property as below :

Code :

Text( Value(txtUnitPrice.Text), "$#,##0.00", Language() )

With these settings we can generate our desired output :

Step 1 : While typing the numbers in the Currency text box field :

Step 2 : OnTabbing out

You can replace the textbox controls with the data card controls in case you are working in an integrated SharePoint PowerApps solution.
