I would like to start the tree grid with all rows collapsed. At the moment I can do this only through load on demand.

Hi Team,
I would like to load Treelist for Blazor by default in Collapsed state.
Also looking for functionality like expand all / collapse all.
Let me how can achieve that?
Thanks,
Aarti
Hello Al,
You can see an example of how to collapse and expand the items from code from our documentation.

So, I installed this version. How can I control state of items?
Hello,
I am attaching to the end of this post a potential workaround that can help start a treelist with all items expanded - to see this work select one item from the treelist, click the button below it to see the second treelist populate with some data.
This is not a feature yet, it relies on re-rendering the treelist by toggling its visibility with an if-block, and that having all data items with hierarchical binding will start them expanded at the moment. Such a workaround should be replaced with a real feature when it becomes available and I cannot guarantee it will work in all cases.
