SharePoint PnP Webcast – Cascading property pane drop-downs with SharePoint Framework

In this PnP Webcast, we covered how to build cascading asynchronous drop-downs for property pane of client-side web part. This is common scenario where lists have a dependency between each other and you filter the results based on the initial selection. Sample code is built with React and is available for you from the SharePoint Framework client-side web parts GitHub repository. Notice that this sample contains two samples - scenario demonstrated with this web cast and another slightly more complex scenario on how to build custom controls for property pane. Custom control option will be covered in separate upcoming PnP webcast. 

Notice. When this webcast was released, SharePoint Framework was available as a Developer Preview release. 

Presentation covers following topics:

  • Use case clarification
    • Building cascading drop-downs which are dependent on each other in the property pane
    • Implementation fo asynchronious queries based on user actions
  • Screenshots of the provide code sample

Web cast demo (5:00) shows following details

  • Use case - How the sample web part built with React works in practice
  • Implementation details from the code - How things are implemented

What is SharePoint / Office DevPatterns & Practices (PnP) web cast series?

SharePoint / Office Dev Patterns and PracticesSharePoint / Office Dev Patterns & Practices (PnP) webcast series covers different patterns, practices and topics around development with Office 365 and SharePoint. Majority of the topics are valid for the Office 365 and SharePoint on-premises. Our objective is to release new around 30 minute long web cast each Monday with few slides and a live demo on the covered topic. All web casts are published at the PnP YouTube channel with additional references on the existing materials.

PnP is community driven open source project where Microsoft and external community members are sharing their learning's around implementation practices for Office 365 and SharePoint on-premises (add-in model). Active development and contributions happen in our GitHub repositories under dev branch and each month there will be a master merge (monthly release) with more comprehensive testing and communications. Latest activities and future plans are covered in our monthly community calls which are open for anyone from the community. Download invite from http://aka.ms/SPPnP-Call

This is work done by the community for the community without any actual full time people. It’s been great to find both internal and external people who are willing to assist and share their learning's for the benefit of others. This way we can build on the common knowledge of us all. Currently program is facilitated by Microsoft, but already at this point we have multiple community members as part of the Core team and we are looking to extend the Core team with more community members.

If you have any questions, comments or feedback around PnP program or this blog post, please use the Microsoft Tech Community (SharePoint Developer group).

“Sharing is caring”
