The cool part of this exercise is not the functionality of the UI, which is quite limited. When you type a message in the text box on the child form, and then click OK, the child form closes and the message that you typed appears in the text box on the main form.
When you click the Open Child Form button on the main form, the child form opens. This little app starts with a main or parent form. But, to show you how to work with multiple forms, I want to start with a really simple example.

What's a Multi-Form App?Ī multi-form or multi-page app is a GUI application with more than one window.

Otherwise, start with the My First Form videos ( Part 1: Build a Simple PowerShell GUI App and Part 2: Controls and Properties) and read the beginner blogs in PowerShell GUIs: Where do I start?
In this blog, we assume that you know how to create a single-form PowerShell GUI app or that you've participated in a Thinking in Events hands-on lab. If you prefer a video, see Create a Muiti-Form PowerShell GUI App (video). When you finish, you'll know how to use the basic multi-form features of PowerShell Studio.įor details about how these features work under the covers, see How Do Multi-Form Projects Work? If you get stuck, the code for this project is on GitHub. The app consists of a parent form that gets data from a child form and displays it. This step-by-step example shows you how to create a very simple multi-form PowerShell GUI app. The instructions in this article were updated in September 2022.
