Issue with igx-tree grid load-on demand
posted

Hi,

I'm using a igx-tree-grid with the load on demand for sub grids as stated in the demo:

https://ko.infragistics.com/products/ignite-ui-angular/angular/components/treegrid/load_on_demand.html

We have combination of search parameters and button and igx-tree-grid. On click of button, we are loading igx-tree-grid load on demand as a result. On the search, the parent row loads perfectly with arrow expand indicator. On click of arrow indicator, children rows are loaded properly.

Issue: When i click on the button to Get Data, Igx Tree Grid loads with parent row and arrow indicator as result. When i click on arrow indicator, sub-grid data (children rows ) are displayed. when i click on button again, i get parent row as result but the arrow indicator is not displaying. I inspected the arrow element and its visibility is hidden in CSS.

To resolve the issue:  I want to re-load /refresh the igx-tree-grid  every time i click on button. But couldn't find any such method.
