Configure web part property pane

Property Pane is defined in SharePoint Framework web part itself. In my case, it is in defined in HelloWorldWebPart.ts file. I’ll be adding one new Toggle field in web part property pane.

Before starting the steps, let me share information that these controls are automatically added with this project by Yeoman. You can see a package under

/node_modules/@microsoft/sp-webpart-base/lib/propertyPane/propertyPaneFields/propertyPaneToggle

Wow! It reminded me the time of programming in C/C++ on Turbo C. Packages are same as header files.

Let’s continue with the steps:

Add new field “customToggle” as boolean type in IHelloWebPartProps.ts

Add this field in exiting group of Property Pane in web part.

File Name: HelloWorldWebPart.ts

Additional Code: Highlighted in screen shot below

Now, add below statement in class HelloWorldWenPart available in file HelloWorldWebPart.ts

<p class=”ms-font-l ms-fontColor-white”>${this.properties.customToggle}</p>

Import PropertyPaneToggle from @microsoft/sp-webpart-base. You need to add highlighted text in HelloWorldWebPart.ts

Now, add default value of newly added property as True in HelloWorldWebPart.manifest.json file. This file is a manifest file of web part which defines web part metadata. Every web part should has this manifest file.

Let’s run the project now. Open command prompt and run following command in current web part’s root directory i.e. helloworld-webpart

gulp serve

It will run the project and launch workbench.html in browser. Just add your web part on the page.

You will see page as below

Click edit icon (i.e. pencil image) on top left corner, it will open web part property pane on right side of desktop.

As soon as you toggle the switch, you will see changes in value on web part false or true. Refer the screen shot below.

And, That’s done 🙂

What’s next?

Well, we’ll go deep in SharePoint Framework programming further and see how can we consume REST APIs in SharePoint Framework (SPFx) web parts? One more thing, we’ll also see, how to debug SharePoint Framework projects in Visual Studio Code?

Hey, in command prompt, why do you not run CTRL+C to stop GULP?
