Advice on updating all rows in a grid after a change is made to a field in that grid

I was able to use the rowselected event to cycle through the lines in the grid and show the percentages that were updated.

The issue is that the isdirty is not being set to true for the rows other than the current row I am updating in the rowselected handler.

I setup my own _isDirty property so that the code will only fire when someone updates the Weight field in the grid.  The FieldUpdated handler sets the _isDirty flag to true so that the percentages get recalculated.

Please don’t confuse MY _isDirty with the IsDirty on the actual row.  I guess my property name might be confusing to someone reading my code.

  protected void _(Events.RowSelected<ICAllocationAccounts> e)
        {

            if (_isDirty == false) return;

            ICAllocationAccounts row = e.Row;

            if (row.AccountSubID != null && row.BranchID != null)
            {
                int totalWeight = 0;
                //int weight = 0;
                int itemCount = 0;
                int itemCounter = 1;
                decimal percentRemaining = 100;

                foreach (ICAllocationAccounts item in AllocationAccounts.Select())
                {
                    if (item.Weight != null)
                    {
                        totalWeight += (int)item.Weight;
                        itemCount++;
                    }
                }

                foreach (ICAllocationAccounts item in AllocationAccounts.Select())
                {
                    if (itemCounter == itemCount)
                    {
                        item.Percent = percentRemaining;
                    }
                    else
                    {
                        item.Percent = Math.Round((decimal)((decimal)item.Weight / (decimal)totalWeight * 100), 2);
                        percentRemaining -= (decimal)item.Percent;
                        itemCounter++;
                    }
                }

            }

            AllocationAccounts.View.RequestRefresh();
            _isDirty = false;
        }
 

Starting here:

If I change the Weight on the 3rd row to 1, it redisplays the percentages correctly.

But when I save only the last row is actually updated to the DB.

Any ideas on how I can force the entire grid to be saved when someone presses the Save button?  Right now, only the row that is updated gets saved.

I changed to the RowUpdated handler.  I can see that this is the better option.  However, I still cannot find a way to change the isdirty flag on the rows that are being changed.  It changes the display value in the View/grid but the two other rows are not being seen as changed.  I’m thinking maybe I just delete the rows and re-add them?  Seems like there must be a better way than doing that (if I can even do that).  I’m going to see if I can do that rather than update them.  

Thank you @Dmitrii Naumov!  I knew it was something simple.  One more brick in my Acumatica foundation of knowledge!  :-)
