Hi! I have some questions about tree grid filtering and structure:
1) I have tree grid that consists of 3 levels. The cell filling of each underlying level starts from next column. If I apply filter to first column I can see only 1 level rows. But I need to show all underlying levels. How can I resolve this? Should I write my own filter strategy for it?

2) How can I apply filter in some action listener after some event?

3) How to drow tree expand icons in second, third etc. columns according the tree level?

Here is tree grid :
index.php/fa/25764/0/

Probably yes because you request a special filter action that needs to take into account the tree structure. Technically the filter checks the attribute you filtered for in the row objects, and the child objects doesn't contain a value there, so they are filtered.

Not sure what you mean. If you want to apply a filter programmatically, set a data value to the FilterRowDataLayer.

Write a custom painter for tree cell rendering.
