I want to disable selection of some rows in multi-selection of igx-grid ignite UI for angular so that if I make those rows are selected by default then the user should not be able to deselect those rows. I will appreciate any help to achieve the goal.
Hello Shahab,
Thank you for contacting Infragistics support.
Yes, the scenario is possible. For the purpose you should use selectRows to select the initially selected rows. Then you should attach to onRowSelectionChange and to cancel any deselections of these rows.
Here is a working sample - https://stackblitz.com/edit/igx-grid-preselected-rows.
