In this blogpost, we will understand the usage of String Interpolation for efficiently concatenating text in Canvas App. Prior to beginning, ensure you’ve subscribed to CRM Crate to keep yourself informed about the latest developments in the Power Platform field.

Power FX is a declarative, formula-based language used within canvas apps in the Microsoft Power Platform. It allows users to create logic and functionality by writing formulas without the need for traditional coding languages. With Power FX, users can manipulate data, control app behavior, and create dynamic user experiences through intuitive expressions and functions. This language empowers individuals to build powerful applications efficiently and without extensive programming knowledge.

Concatenating text in Canvas App using String Interpolation method

Below starting with string interpolation, let us first concatenate strings using old conventional method. Below are the two old conventional methods used for concatenating string using Power FX formulas.

The below code demonstrates concatenating strings with dynamic objects using Concatenate Power FX formula.

Concatenate("There are", Object2Text.Value, " ",Object1Text.Value," recently seen in jungle! ")

The below code demonstrates concatenating strings with dynamic objects using (&) operator.

"There are"& Object2Text.Value& " "&Object1Text.Value&" recently seen in jungle!"

String interpolation is a handy way in programming to create dynamic strings. Instead of awkwardly piecing together bits of text and variables, you can directly insert variables or expressions into a string template. This means you just set up your string with some special markers where you want your variable values to appear, and when the string is processed, those markers get replaced with the actual values or results of expressions.

In Canvas App, the unique marker used for string interpolation is ($) symbol. The below code demonstrates concatenating string template with dynamic objects using String Interpolation method.

$"There are {Object2Text.Value} {Object1Text.Value} recently seen in jungle! "

The big advantage of string interpolation is that it makes your code cleaner and easier to understand. Instead of messing around with joining strings and variables, you just put your variables right into the string where you want them. This makes your code shorter and less confusing.
