One of the capabilities of the property pane is to configure its update behavior, which can be set to reactive or non-reactive.
By default, the update behavior is reactive and enables you to see the changes as you edit the properties. The changes are saved instantly when the behavior is reactive. In the console, stop the local web server by terminating the process.
Enter the following command to open the web part project in VS Code or use your favorite editor :. If you get an error when executing this command, you might need to install the code command in PATH. TypeScript is the primary language for building SharePoint client-side web parts. SharePoint client-side development tools are built using TypeScript classes, modules, and interfaces to help developers build robust client-side web parts.
Any client-side web part should extend the BaseClientSideWebPart class to be defined as a valid web part. BaseClientSideWebPart implements the minimal functionality that is required to build a web part. This class also provides many parameters to validate and access read-only properties such as displayMode , web part properties, web part context, web part instanceId , the web part domElement , and much more. This property definition is used to define custom property types for your web part, which is described in the property pane section later.
The DOM element where the web part should be rendered is available in the render method. This method is used to render the web part inside that DOM element. This model is flexible enough so that web parts can be built in any JavaScript framework and loaded into the DOM element. The property pane is defined in the HelloWorldWebPart class. The getPropertyPaneConfiguration property is where you need to define the property pane.
When the properties are defined, you can access them in your web part by using this. Notice that we're executing an HTML escape on the property's value to ensure a valid string. To learn more about how to work with the property pane and property pane field types, see Make your SharePoint client-side web part configurable. Let's now add a few more properties to the property pane: a checkbox, a drop-down list, and a toggle. We first start by importing the respective property pane fields from the framework.
Update the web part properties to include the new properties. This maps the fields to typed objects. Replace the getPropertyPaneConfiguration method with the following code, which adds the new property pane fields and maps them to their respective typed objects. After you add your properties to the web part properties, you can now access the properties in the same way you accessed the description property earlier.
To set the default value for the properties, you need to update the web part manifest's properties property bag. The HelloWorldWebPart. Every web part must contain this manifest. Now that we have introduced new properties, ensure that you're again hosting the web part from the local development environment by executing the following command.
Privacy policy. You can create and customize a web part by adding a Web Part item to any SharePoint project and then editing the code file for the web part or by using a designer. For more information, see How to: Create a SharePoint web part by using a designer. For more information, see SharePoint project and project item templates.
In the Name box, specify a name for the web part, and then choose the Add button. The web part appears in Solution Explorer. For more information about the files that a web part includes, see Create web parts for SharePoint.
