Now i want center the Columns (is that possible)
and when i resize the form (the Grid hat its Property Dock set to fill) i want to center the Columns/Content

If you have a single-band grid, then you could center the grid content like this:

        private void CenterGridContent(UltraGrid grid)
        {
            int gridWidth = grid.Width;

            UltraGridBand band = grid.DisplayLayout.Bands[0];
            int bandWidth = band.GetExtent(BandOrigin.PreRowArea);

            int difference = gridWidth - bandWidth;
            band.Indentation = difference / 2;
        }

Call this method from Form_Load and also from the grid_Resize event. I tried it out and it seems to work very well for me.
