Mike,

I have submitted a feature request for this.  I have been trying to find a way to implement the functionality that we want by using a CreationFilter.  My theory was that I can Offset some of the UIElements in the grid to create a space where I can create my own custom template add row that will always show in the grid even when grouping.  I have successfully created this space by using the following code:

public void AfterCreateChildElements(UIElement parent)

        {

if (parent is RowColRegionIntersectionUIElement)

            {

                foreach (UIElement element in parent.ChildElements)

                {

                    if (!(element is BandHeadersUIElement))

                        element.Offset(0, 23, true);

                }

            }

         }

This provides me with the space I need to attempt to add my own set of controls to mimic an add row.  From the BandHeadersUIElement I can get each visible ColumnHeader and the Editor that is used for that column.  My problem is that I can't seem to create those editor controls and add them as child elements of the RowColRegionIntersectionUIElement.  Is it even possible to do this?  I have tried many different things here.  It seems like you can only add simple things like text, images, and buttons.  What I really want to do is add my own row here, or add a series of controls that match the editor for the column and I can size and space them accordingly.  (dates, combos, etc)

With all my efforts I am starting to think this isn't possible to do, but I wanted to post first to verify.

Thanks for your help,
