Concatenate PowerApps Gallery Items and display in a HTML Textbox with Line breaks

HTML text input box in PowerApps doesn’t recognize Char(10) and Char(13) to provide the space and line breaks. So, I had to use the Substitute function to get line breaks in HTML Text input box.

Substitute( TextInput1.Text, Char(13), “<br/>”)

My scenario was:

Concatenate values (Column1 and Column2) from PowerApps Gallery and display in HTML Text with line breaks for each record and Column1 in bold.

Set(varGalleryItemsConcat, Concat(Gallery.AllItems,Substitute(Concatenate(““, Column1.Text,”“, Char(13)&Column2.Text&Char(13)&Char(13)),Char(13),”

Add varGalleryItemsConcat variable to HTMLText property

You will see the data HTML text input box as follows. Let’s assume there are 3 rows in gallery

Column1 row1 value Column2 row1 value

Column1 row2 value Column2 row2 value

Column1 row3 value Column2 row3 value

PowerApps – Double quotes in a string

In PowerApps we use double quotes in the beginning and ending of the string but to get double quotes with in the string we need to use Char(34).

Here is the example:
