Thank yo so much, Mike. It works fine.

Oh, so you are doing the opposite of what the original poster in this thread asked. Okay... that's pretty easy to do with a CreationFilter.

        private void Form1_Load(object sender, System.EventArgs e)
        {         
            this.ultraGrid1.CreationFilter = new ButtonCreationFilter();
        }

    public class ButtonCreationFilter : IUIElementCreationFilter
    {
        void IUIElementCreationFilter.AfterCreateChildElements(UIElement parent)
        {
            if (parent is CellUIElement)
            {
                UIElement cellButtonUIElement = parent.GetDescendant(typeof(CellButtonUIElement));
                if (null != cellButtonUIElement)
                {
                    Rectangle rect = parent.RectInsideBorders;
                    rect.Inflate(-3, -3);
                    cellButtonUIElement.Rect = rect;
                }
            }
        }

        bool IUIElementCreationFilter.BeforeCreateChildElements(UIElement parent)
        {
            // do nothing
            return false;
        }
    }

Hi Mike,

The problem I'm trying to solve is to make button in column to not filling all the entire cell but at the same time all other column's content should fill all the cell.

Is it possible?

Hi Eugene,

I'm confused. I tried this out and I set CellPadding on the override to 5 in a grid with a button column. But the padding has no effect on the button column. The button still fills the entire cell.

So what's the problem you are trying to solve?

I'm setting style of a column to Button.
