When building classic web parts, web part properties were isolated from SharePoint, and their values were managed by end-users. SharePoint Framework offers you a new set of capabilities that simplify managing web part properties’ values and integrate them with SharePoint Search.
How to add property fields to webpart code?
We will see how to add and use these fields into our webpart. Open the webpart code project using your Visual Studio code and get into the webpart.ts file mine is ‘PropertypanesettingsWebPart.ts’ At the top import from ‘@microsoft/sp-property-pane’ is the section where we need to add these fields, so they get imported for further usage in code
How is the targetproperty defined in a web part?
The targetProperty defines the associated public property on the web part for that field type and is also defined in the props interface in your web part. To assign types to these properties, define an interface in your web part class that includes one or more target properties.
Every field type method is defined as follows, taking PropertyPaneTextField as an example: The targetProperty defines the associated public property on the web part for that field type and is also defined in the props interface in your web part.
HTML web part properties are also searchable, so users can look for any keywords included in the property value. Property value types isImageSource and isLink are meant to be used for web part properties that include nothing else but a link to an image or a file stored in SharePoint.
When is a web part property defined as ishtmlstring?
When a web part property is defined as isHtmlString, SharePoint first of all removes any unsafe HTML, such as script tags, from the property value. The HTML that remains can be considered safe to render on a page.
The propertiesMetadata getter returns an object, where the property is a string and specifies the name of the web part property, and the value is an object specifying how SharePoint should handle that particular property. When overriding the propertiesMetadata getter, you don’t have to list all the web part properties.
Run the following command to verify that the project is running: In the web browser, add the List items web part to the canvas and open its properties. Verify that the value set for the List property is displayed in the web part body. The SharePoint Framework offers you a standard dropdown control that allows users to select a specific value.
Can a web part be indexed by SharePoint?
Setting multiple properties will most likely lead to undesirable results, and you should avoid it. By default the value of a web part property is not indexed by SharePoint Search and it’s not processed by SharePoint in any way. It’s passed to the web part exactly how it’s been entered by the user configuring the web part.
