Updating data row in master grid of a master-detail formation

[Gerald Peng]

Hi There,

I have a master-detail grid setup, where most the edits are being done on the master grid, which contains an order. The detail grid is a holding grid of items that are part of the order. There is a separate grid next to the detail grid that contains the full list of available items, with controls that allow the user to move an item from the full list of available items to the holding grid of items and vice versa.

On the master grid, there is a count of item types. This count also drives dropdown values at the master level that classifies the order. I have been successful in updating the underlying object using the OnActionBegin event handler, however, the counts do not appear on the master grid while in in-line edit mode. Should I be modifying the data at the object level, or manipulating it through the grid?

Below is the class structure

public class Order

{

 public ICollection<Item> Items

 public int CountOfBigItems => Item.Where(p => p.Size == Size.Big).Count; // Referenced in the grid

 public int CountOfSmallItems => Item.Where(p => p.Size == Size.Small).Count;  // Referenced in the grid

public Guid OrderSize => goes to a lookup based on the counts above, and assigns appropriate guid

}

Thanks in advance for your help!

Hi Naveen,

I'll find a way to get you a screenshot/video. In the meantime - I want the CountOfBigItems and  CountOfSmallItems updated in the master grid during​ editing in the master grid (as the row in the master grid must be in edit mode in order for the details to be editable), and not have said edit mode closed when the count is changed. I have tried ObservableCollection and INotifyChange for the master grid objects, and ObservableCollection for the child objects, and the issue is the when a change is made to the counts, edit mode is automatically closed off and the record is saved before the user can select save/cancel.

Gerald.
