Hi Gowrishankar,

Thanks for the reply. But my question is not about how to load the data to improvement performance. I am asking how to insert checkbox in every repeating rows in every layer of the tree grid and control the checkbox behavior.

Here is the scenario: A company has multiple divisions, and each division has one or multiple units, and each unit has one or multiple workgroups.  Tree/tree grid is best suited to present this structure. The tricky part is we need checkbox for all rows in all layers (division, unit, and workgroup): select/deselect at division level will select/deselect all units/workgroups under the division, and select/deselect at unit level will select/deselect all workgroups under the unit. I couldn't find anything OOTB settings that can achieve this. The only way I can think of is add this checkbox property in each layer, and at click, refresh the layout and call an activity to set correspondent checkbox properties. Since this kind of multi-select behavior is not rare in real life UI behavior design. Was wondering if there is better way to achieve this.

Appreciate the help,

Hao
