Make Keys.Enter work like Keys.Tab does not work on TemplateAddRow

this is my code

/ / remove the KeyActionMappings for Keys.Enter

foreach (Infragistics.Win.UltraWinGrid.GridKeyActionMapping ogKam in Grid.KeyActionMappings)
            {
                
                if (ogKam.KeyCode == Keys.Enter)
                {
                 Grid.KeyActionMappings.Remove(ogKam);

                }

          }

 

// then add new mapping  for Keys.Enter so it's work like Keys.Tab

    foreach (Infragistics.Win.UltraWinGrid.GridKeyActionMapping ogKam in Grid.KeyActionMappings)
            {
                if (ogKam.KeyCode == Keys.Tab)
                {
                  newKam = new Infragistics.Win.UltraWinGrid.GridKeyActionMapping(Keys.Enter, ogKam.ActionCode, ogKam.StateDisallowed, ogKam.StateRequired, ogKam.SpecialKeysDisallowed, ogKam.SpecialKeysRequired);
                Grid.KeyActionMappings.Add(newKam);
                }
            }

Result :

Keys.Enter still not work on TemplateAddRow like Keys.Tab

After I press Enter it's move to the next new row. How to make it move to next cell on TemplateAddRow ? 

Solution Please..

Thanks

    This code will not work properly.

    You should never use Remove or Add inside of a foreach for a collection because Remove will change the items in the collection and mess up the enumerator. The proper way to remove items from a collection like this is to loop through the collection backwards by index. Like so:

     

    for (int i = Grid.KeyActionMappings.Count; i >=0; i--)
                {
                    Infragistics.Win.UltraWinGrid.GridKeyActionMapping ogKam = Grid.KeyActionMappings[i];
               
                    if (ogKam.KeyCode == Keys.Enter)
                    {
                        Grid.KeyActionMappings.Remove(ogKam);
                    }
                }
