Rerendering on state update with template

[Richard Craig]

If you add a template to a treeview and update state, the whole treeview is rerendering.

It doesn't do this without the template. Is there any way to prevent this?

example...

If you remove the nodeTemplate it works fine.

Richard, We are glad to announce that our Essential Studio 2022 Volume 4 Main release v20.4.0.38 is rolled out and is available for download under the following link.

Essential Studio 2022 Volume 4 Main Release v20.4.0.38 is available for download | Syncfusion Forum Assist. 

In this release, we have provided the support “To prevent the component from re-rendering while the state is being updated”. To access this feature, we suggest you update the package to 20.4.38 and we include the sample in the latest version for your reference.

If the templates are defined in nested directives of the component, then you need to pass the statelessTemplates property array value as "nodeTemplate" instead of the template names.
