I need to filter every sub grid, searching for a particular string. My app has an input and a hierarchical grid similar to the one in the following example: https://www.infragistics.com/products/ignite-ui-angular/angular/components/hierarchicalgrid/filtering
For example, every album in every sub grid that contains the word "house". Is there a way to filter programatically sub grids inside the hierarchical grid?
I've tried naming the row island and calling filter() and filterGlobal() methods with no success.
Thanks
