New Drag and Drop ListView @pnp/spfx-controls-react

This post is about a feature that i was expecting some and was launch in @pnp/spfx-controls-react in version V2.1.0, that was the capability to use drag and drop of files in ListView and capture the file object to make the associated actions afterwards.

The following example explain how we can use the ListView Control to use drag and drop option and  retrieve the file object from the new handler onDrop event and copy to a SharePoint Document Library.

The first thing that needs to be made is to configure the ListView properties in the control with the following:

  • dragDropFiles as True, activates the drag and drop option.
  • OnDrop handler, Method this._getDropFiles retrieves files from drop handler.

The handler  OnDrop retrieves the files object that allow us to manage the content as we want.
This can be upload files to a libraries, validate what type of file, size of file, naming with capability or renaming, in the end multiple business requirements that can be stop or validated before file is included in the system.   

When you test the control using "gulp serve" base in a existing Document Library you can see the normal list of documents as working in the older version. 

To activate the drag and drop pick some files and drag to ListView area and upload information focus will appear, in this moment you can leave the files and the upload process can start.  

After you drop the files in the List View area the handler drop sends objects to method _getDropFiles and uploads the files to a Document Library as explain the code below.

  * Method that retrieves files from drag and drop
  * @param files
 private _getDropFiles = (files) =>{
  let count=0; 
  for (var i = 0; i < files.length; i++) {
    var file = files[i];
    if (file != undefined || file != null) {
      let spOpts : ISPHttpClientOptions = {
        headers: {
          "Accept": "application/json",
          "Content-Type": "application/json"
        body: file        

      var url = `${this.props.context.pageContext.web.absoluteUrl}/_api/Web/GetFolderByServerRelativeUrl('Shared%20Documents')/Files/Add(url='${}', overwrite=true)`;, SPHttpClient.configurations.v1, spOpts).then((response: SPHttpClientResponse) => {

        console.log(`Status code: ${response.status}`);
        console.log(`Status text: ${response.statusText}`);
        response.json().then((responseJSON: JSON) => {
          if(count=== (files.length) ) {

The following method is a reuse function componentDidMount to make refresh of ListView to display the uploaded files that was managed in method below.
public componentDidMount() {
    const restApi = `${this.props.context.pageContext.web.absoluteUrl}/_api/web/GetFolderByServerRelativeUrl('Shared%20Documents')/files?$expand=ListItemAllFields`;
    this.props.context.spHttpClient.get(restApi, SPHttpClient.configurations.v1)
      .then(resp => { return resp.json(); })
      .then(items => {
          items: items.value ? items.value : []
After refresh the ListView should display the files as defined in the method.

The demo below uses "@pnp/sp": "^2.2.0" to upload stream into SharePoint Library.
  * Method that retrieves files from drag and drop
  * @param files
  private _getDropFiles  = async (files) => {
    for (var i = 0; i < files.length; i++) {

      const fr = await  sp.web.lists.getByTitle("Documents").rootFolder.files.configure({
        headers: {
            "content-length": `${files[i].length}`,
    }).add(files[i].name, files[i]);
Simple and in my opinion a very useful feature that was missing for some time in my point of view.
It's always interesting how the concept of open source give opportunity that everyone could contribute, like i did with this new feature ListView Drag and Drop.
If you have a good idea for a improvement and feature that you can identify a very good business case, you can always propose or bug fixing to PNP community, they are pro active and very open to improvements.

Hope you like this simple articles,

List of Frameworks that could help you start with SPFX

Since the last years the PnP team is creating a very solid and super fast evolutionary SharePoint framework where developers can make their work, a real integration with Microsoft Teams and Microsoft Graph, not only SharePoint, a real "stonk" case of growth :).

It's really impressive what everyone involve was able to do at this point, since documentation, videos to code..., i remember the beginning of the PnP concept and follow what Vesa Juvonen was generating on the initial steps, cannot believe the amount of years that already past...

But at this point i see people creating samples for everything and reuse existing frameworks without clear information, for people that is working, this can be very confusing on what is provided by SPFX or what needs to be added, i don't what to talk about the SPFX versioning that another article on how to keep everything on track.

But if you are beginning and can understand in what are you in, this Frameworks could help start you development and response the normal question that you make, where i can add a calendar, can i include a metadata control and all this questions that doesn't have a direct  but external answer. :) 

Here a compilation of some Frameworks that i found very useful, you can use to include in your SharePoint Framework (SPFX) solutions.


Full featured image editor using HTML5 Canvas. It's easy to use and provides powerful filters.


A full-sized drag & drop JavaScript event calendar

SharePoint Framework React Controls

Reusable React controls for your SharePoint Framework solutions

PnP Modern Search solution

This is a open source solution that helps you to build engaging search based solutions in the SharePoint modern experience.


Fluent JavaScript API for SharePoint and Microsoft Graph REST APIs


Simple, clean and engaging charts for designers and developers


A collection of UX frameworks for creating beautiful, cross-platform apps that share code, design, and interaction behavior.


Popular icon toolkit


Full-featured photo image editor using canvas. It is really easy, and it comes with great filters.


Pure Javascript OCR for more than 100 Languages

All NPM installers commands can be found in the following web site.

I am sure there are a bunch of other frameworks i didn't reference that make a huge difference, but this ones will give you a huge boost to start and became motivated to develop in this platform.
Lot of the are being used in the samples provided by the PnP team.

SharePoint Framework
Samples SPFX

Personal thought:
I remember when i was starting (in 1985 copying code from a magazine to my spectrum 128k that generate a game of falling pieces and needed to escape from them. Draw a circle with a line and thinking "i just draw Saturn, how fascinating this is.", more than 30 years and now i am going to internet to find code... some things never change)

Microsoft Flow - Copy Folders with documents between Sites using REST

New day, new possible business case for Microsoft Flow... for this example how to copy folder with files between sites using Microsoft Flow Action.

Following small Business Case:

  • Provisioning of Sites and Subsites base in request (example article).
  • Sub Site needs to have Folder with Document Templates that needs to be filled by users.
  • Template folder is in root Folder and needs to be copy into Sub Site.
  • Create Flow Action base in REST to copy folder template to new Sub Site when site is created.

For this Flow i use the Send an HTTP request to SharePoint and use the following REST Service call "SP.MoveCopyUtil.CopyFolder
", this method has some time (since 2016) and is very used in JSOM and here a simple article explaining how to use it:

For this example i have a Modern Team Site where are stored the Template folder files that should be available in the provisioned Sub Sites, as shown in the image below.

After definition of Root Folder where are stored the folder/Files to be copy, you can access to Microsoft Flows and create a new Flow and add the following Flow Action "Send an HTTP request to SharePoint" there you can include the HTTP call with the following source url to destination Folder to be copied.

HTTP Method:

Site URL: {Site}

Method: POST
URI : _api/SP.MoveCopyUtil.CopyFolder
"srcUrl": "https://{tenant} Documents/Templates", "destUrl": "https://{tenant} Documents/Templates" 

The Flow definition should be enough to be executed.
You can manually execute the Flow and validate their success of the Action. 
You can use the flow history for more details, as show in the image below.

Looks like the Flow output is ok, then you access to your Sub Site Document Library and very if Folder "Templates" appears as shown in the image below.

Three articles in a week should be a record to me, looks like my small burn out is slowing disappearing...

Hope you like it,

Microsoft Flow - Excel Actions To Copy Table Rows by Recurrence Timeline

After my last Article "Microsoft Flow - Provision SharePoint Online Modern Sites using REST" continue to explore Microsoft Flow and their different options, today made investigations regarding the Excel Flow Actions and SharePoint Online with the following Business Case:

  • Have Excel document where are stored entries from users.
  • Excel Document is stored in SharePoint Online Document Library.
  • Every 30 days should archive in different Excel Table the entries from that Month
    • Copy from Table 1 to Table 2 (Archive)

Microsoft Flow - Excel Actions identified boundaries:

  • Get rows method can be up to 2048 items. 
  • The action can list up to 256 rows

SharePoint Online - Excel location

This example try to use all Office 365 services and capabilities and SharePoint Online Document Library was used to store the excel demo as show in the image below.

List Excel Table View - Table 1

After access the excel example we are able to see the entries from Table 1 where are listed multiples entries for this demo to be used in the copy between tables.

Microsoft Flow

Recurrence - Action

Access to Microsoft Flow Page and create New Flow using Blank Template.
To fulfill the job timer was used a recurrence Action where was defined interval of 1 time by month to be executed as show in the image below. 

List of Action "Preview Excel"

After Recurrence is defined a new Action was defined and list the Excel options, for this example "Excel Online (Business)" to use SharePoint Online Location where is stored the Excel file.

List rows present in a table - Action

This action lists the Table 1 items base in a query from the Excel File to return the selected items to be used to copy in the Table 2.

Property Options:
Location - SharePoint Online Site 
Document Library - Document Library from selected SharePoint Online.
File - Excel File Location from Document Library
Table - Table from Excel used as Datasource
Filter Query query option to select which items to return. 
Order byquery option to specify how to sort the items in your query return set
Top Count - query option to specify how much items should return from the return set
Skip Count - option enables you to skip over items until the specified item is reached and return the rest.

For this example were defined 10 items to make the example associated as show in the image below.

Add an apply to each - Step

This step manage the result item collection from last Action where Query from Table 1 was made to be used and copied in Table 2.

Add a Row into Table - Action

As defined in my last Action a new parameter with Item Collection rows  from my last query are stored in the parameter "value".

To add new Row in new 

Location - SharePoint Online Site 
Document Library - Document Library from selected SharePoint Online.
File - Excel File Location from Document Library.
Table - Table from Excel used as destination Datasource.
[Columns Name] - Column Name from Excel Table to include new Items.

To call the item Collection row in the new Row/Column, i would like to recommend the following expression:

  • item()['Column Name']

Below the example on how to get Item details.

Execute Flow by request - Run now

After creation of Flow and for testing purpose we can manually execute the Flow using the "More" option and select "Run now" and wait to finalize their execution.

Microsoft Flow - Report

After execution of Flow and their success, we can see the reports about the returned Rows and HTTP communication about the copied items between Excel Tables, "were defined 10 rows for this example".

List Excel Table View - Copy output to Table 2

After execution of the Microsoft Flow and validation of execution, users can access to Excel Document and access to support "Table 2", for this case were stored in a separated worksheet and the values should appear as shown in the image bellow.

and another example made using Excel and Microsoft Flows.
Office 365 getting better every day...

Here the full Flow:
