File list component in Microsoft Graph Toolkit

The File List component displays a list of multiple folders and files by using the file/folder name, an icon, and other properties that you specify. This component uses the mgt-file component. You can specify a specific drive or site, display a list of files based on insight type (trending, used, or shared), or provide queries to a custom list of files. The component also provides the option to allow users to upload files to a specified location in One Drive or SharePoint.

Example

The following example displays a file using the mgt-file-list component. You can use the code editor to see how properties change the behavior of the component.

The following example changes the behavior of the component to fetch a file list from a specific query.

<mgt-file-list
  file-list-query="/me/drive/items/01BYE5RZYJ43UXGBP23BBIFPISHHMCDTOY/children"
></mgt-file-list>

The following example changes the behavior of the component to fetch a file list from a folder by providing the folder ID.

<mgt-file-list item-id="01BYE5RZYJ43UXGBP23BBIFPISHHMCDTOY"></mgt-file-list>

The following example changes the behavior of the component to fetch file list from a group by providing the group ID and folder path.

<mgt-file-list
  group-id="8090c93e-ba7c-433e-9f39-08c7ba07c0b3"
  item-path="/Design"
></mgt-file-list>

The following example changes the behavior of the component to fetch file list from a user by providing the user ID and folder ID.

<mgt-file-list
  user-id="48d31887-5fad-4d73-a9f5-3c356e68a038"
  item-id="01BYE5RZYFPM65IDVARFELFLNTXR4ZKABD"
></mgt-file-list>

The following example changes the behavior of the component to fetch file list by providing the insight type.

<mgt-file-list insight-type="shared"></mgt-file-list>

The following example enables the file upload feature.

<mgt-file-list enable-file-upload></mgt-file-list>

The following example limits the maximum number of files that can be uploaded to 5.

<mgt-file-list max-upload-file="5" enable-file-upload></mgt-file-list>

The following example limits the maximum file size that can be uploaded to 10,000 KB.

<mgt-file-list max-file-size="10000" enable-file-upload></mgt-file-list>

The following example excludes upload of files with file extensions ".doc, .pdf".

<mgt-file-list
  excluded-file-extensions=".doc,.pdf"
  enable-file-upload
></mgt-file-list>

Methods

Method Description
reload(clearCache = false) Call the method to reload the component with potential new data based on its properties. Pass true to clear the cache before reloading.

Reloading example

You can use the reload() method that is exposed on mgt-file-list by getting the mgt-file-list reference from the DOM and triggering the method in a button using the click event.

<mgt-file-list insight-type="shared"></mgt-file-list>

<button id="reload-btn">Reload Files</button>
const fileList = document.querySelector("mgt-file-list");
document.getElementById("reload-btn").addEventListener("click", () => {
  // passing true will clear file cache before reloading
  fileList.reload(true);
});

Events

Event When is it emitted Custom data Cancelable Bubbles Works with custom template
itemClick Fired when the user selects a file. Selected file No No Yes, with a custom file template.

For more information about handling events, see events.

Data type Data context Description
default files: list of file objects The default template replaces the entire component with your own.
file file: file object The template used to render each file.
no-data No data context is passed The template used when no data is available.
