Expand specific node

[Mark Goldin]

I need to expand specific nodes after data is received from the server. I am trying [expandedNodes]="[1]", not working. (created)='onCreated($event)' or (dataBound)=' onCreated ($event)' not working either. So, what is the idea?

Hi Mark,

Greetings from Syncfusion Support.

Thank you for providing the details. Based on your scenario, we prepared a sample using the TreeView component with remote data and bound the ExpandedNode property. While testing the sample, the node expanded as expected, and we were unable to replicate the reported issue.

We tested this scenario multiple times, but the issue could not be reproduced on our end.

If the issue persists on your end, please share the following details to help us investigate further:

• Your TreeView configuration
• How the data is loaded into the TreeView
• Version of the Syncfusion package you are using
• Environment used to test the application
• Steps to reproduce the issue
• A video demonstrating the issue
• A minimal reproducible sample
• Any errors observed in the browser console

Please try to reproduce the issue using the sample we have shared and let us know the outcome. We are happy to assist further if needed.

Regards,
Praveen Sellappan
