Hi Himanshu,

You can have a look at this documentation which discusses on Accessing Table Views in a Hierarchical Grid.

Thanks,

Hello Himanshu,

The help article that Shinu provided should help accomplish your requirement. The main idea is first access the parent data item, cast it to GridDataItem and retrieve the value from the column in interest:

GridDataItem parentItem = childItem.OwnerTableView.ParentItem;

If any additional assistance is needed, please feel free to get back to us.
