  4. update data causing the whole treeview to re-rendering.

update data causing the whole treeview to re-rendering.

I found there is already one reported. But the issue does not seem to be updated.

In the final example: https://stackblitz.com/edit/react-vtew1m?file=src%2FApp.js

It does not apply the nodeTemplate, it should be like this:

      <TreeViewComponent
        fields={fields}
        nodeTemplate={nodeTemplate} 
        statelessTemplates={['nodeTemplate']}
      />

Then you will find the issue is still the same.

Hi Zero,


We have reviewed your query and understand that you are experiencing a re-rendering issue with the TreeView component, even though you have used the "statelessTemplates" property. Upon further validation, we have identified that you are currently using Syncfusion - Navigation version 20.2.44. However, support for the "statelessTemplates" property was provided in version 20.4.38. Therefore, we recommend upgrading your version to 20.4.38 or a higher version.


We have attached the release notes for your further reference.

We have also upgraded your provided sample to the latest version and tested it. The TreeView control no longer experiences re-rendering issue and functions as expected. We have attached a sample for your reference.
