Please provide built-in expandRow() and collapseRow() methods.

Thank you

Provide an option to set a default value for the parentId field just like the defaultValue of the Kendo UI for jQuery TreeList:

Thank you

Is there some documentation or example of how to sort on a TreeList of the entire hierarchy when the hierarchy is created on demand. That is, I want the sort to order the parent node along with its children.

Autosize on treelist with locked columns does not work

When the width of the grid exceeds the column lengths, you would expect autosize to expand and fill the rest of the space evenly.

Is there an example or documentation to manipulate a TreeList I want to add several rows in the TreeList and then save all the changes made in the component. Examples (AddChild and AddSibling). How could I handle that scenario where everything I do in the TreeList is stored temporarily until confirmed with a save button.

How can I reload the treeList without expanding the children, I only want to show parents (the first level nodes)?
