I've been looking at the example here: http://www.igniteui.com/tree-grid/load-on-demand
Before expanding a node: when the grid is unfiltered the top level 381 node has the expand icon next to it. However when I filter for 381, the expand icon is lost.
Is there a way of making "All expandable unexpanded nodes be expandable" IE if it was possible to expand it before loading its children then is it possible to let be be expanded when it meets filtering requirements?

Thank you for update.
Please let me know if i may be further assistance.
Any news on this? I also need this feature and looks like the "Suggest an idea" is down...
The igTreeGrid Filtering feature has two display modes -"showWithAncestors" and "showWithAncestorsAndDescendants". With the second one the children of the items that match the filtering criteria will also be rendered in the grid, so the expansion indicators will be retained.
You can read more about the display modes in our documentation:
Here’s an example on how to set the "showWithAncestorsAndDescendants" mode via the MVC wrapper:
Let me know if that solves your issue.
