Question:

How to update value of a call all parent rows when a particular row is expanded in case of remote data binding
Eg: Syncfusion-content - Ej2 Angular Docs - StackBlitz

Expand first row, expand any other nested row, all parent rows need to be updated for a particular cell lets say Duration to be made 1000. How to achieve it?
Important: Remote data binding is there and not local data

Hi Tuariq,

Greetings from Syncfusion

You can update the cell value in the Tree Grid using the setCellValue method on expanded and collapsed events. But this will update cell value only in UI and not in the underlyng data source. If your requirements for updating values are not in the UI and the server kindly get back to us. This will help us provide a precise solution tailored to your needs.

Looking forward to your response.

Regards,
