Thanks Mike, I have managed to do it by removing the SpanY as there is no other way.

Hi Ponnu,

    I'm afraid I have no idea why that's happening. I guess the GridBagLayout is using the row UIelement as the size of the layout area, so this is affecting the size of the elements within the layout. I'm not sure what else you can do about that. As I said, I really don't think what you are trying to do is feasible. 

Hi Mike,

I have made a small sample to show it to you as mine is pretty huge one.

As you could see I have reduced the height of first row which resulted in Description Cell height change.

This is the code that I use to reduce the height

        public bool BeforeCreateChildElements(UIElement parent)
        {
            UltraGridRow rowActive = (UltraGridRow)parent.GetContext(typeof(UltraGridRow));

            if (parent is RowUIElement && rowActive.Index == 0 && parent.Rect.Height > 170)
            {
                parent.Rect = new Rectangle(parent.Rect.X, parent.Rect.Y, parent.Rect.Width, parent.Rect.Height - 20);
            }
            return false;
        }

Hope you could see the problem, I would appreciate your help.

Thanks

 Hi Ponnu,

    I don't really understand. Changing the Rect of a UIElement cannot possibly have any effect on the SpanY property.  

Hi Mike,

Thanks, CreationFilter did the trick. But I have little problem with an element spanning across vertically in row layout of the card. Once I change the height of the RowUIElement within BeforeCreateChildElements of CreationFilter, it looks like the SpanY gets reset and does not work.

Would appreciate your help reg. the same.

Many Thanks
