Fix SharePoint List View Web Part Rendering Custom Links Incorrectly
Question details
The user needs to resolve an issue where a SharePoint list view web part fails to render JSON-formatted links correctly after the underlying source list is recreated.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Displaying customized dynamic links in a SharePoint list view web part using JSON formatting.
- Observed behavior
- The custom JSON formatting works perfectly in the native SharePoint list view but breaks within the web part, as the web part fails to recognize the updated source parameters.
Verify that your JSON formatting code works correctly in the native SharePoint list view to rule out any syntax errors before troubleshooting the web part itself.
Remove and Re-add the List Web Part
Deleting the faulty web part and adding a fresh instance forces the SharePoint page to recognize the new source list IDs.
When a SharePoint list is recreated, its internal GUID changes. The web part may retain cached references to the old list's IDs, causing custom formatting scripts to fail. Replacing the web part resets this connection.
Navigate to the SharePoint site page containing the faulty web part and click the 'Edit' button in the top right corner.
Select the List view web part that is failing to render the links, and click the 'Delete web part' (trash can) icon on the toolbar.
Hover your mouse over or below the section, click the '+' icon to add a new web part, and select 'List' from the web part gallery.
Choose the newly recreated source list from the prompt. Publish or save the page to apply the changes and test your JSON links.
Validate Source List and View References
Ensure the web part is explicitly targeting the correct custom view where the JSON formatting is applied.
Escalate to Microsoft 365 Support
If replacing the web part does not permanently resolve the source recognition failure, escalate the bug to Microsoft.
Boost Productivity with WPS Office
While Microsoft SharePoint manages your lists and web portals, you can rely on WPS Office as a lightweight, free alternative for your daily document creation needs. It offers exceptional performance without heavy system requirements.
- 1. Download the installer: Visit the official WPS website and click on the 'Free Download' button.
- 2. Install WPS Office: Run the downloaded installer and follow the quick on-screen setup instructions.
- 3. Open your files: Launch WPS Office and immediately start opening or editing your existing Microsoft Office documents.
Frequently Asked Questions
Why does my JSON formatting fail in the web part after list recreation?
When a SharePoint list is recreated, its internal unique ID (GUID) changes. The web part on the page may retain a cached reference to the old list's IDs, causing custom formatting scripts to fail until the web part is completely replaced.
Does standard list view formatting require custom SharePoint web parts?
No, standard JSON column and view formatting can be applied directly to the out-of-the-box SharePoint List web part without needing custom SPFx development.
Will clearing my browser cache fix the SharePoint web part rendering issue?
Usually not. This specific issue is related to how the web part configuration saves the source list data on the server side, which is why removing and re-adding the web part is required to force an update.
