    Is there a quick way to center groups similar to the attached picture? Or do i have to do the calculations manually in the resize event?

    I suppose i could do something along the lines of this (ignoring title and padding) in the resize event. But then i get into positioning each and every group. Also, is there not an easy way to calc the current size of a group.

      float newWidth = (radPanorama1.Width/2) - (tileGroupElement1.CellSize.Width * tileGroupElement1.ColumnsCount)/2;
     
    float newHeight = (radPanorama1.Height / 2) - (tileGroupElement1.CellSize.Height * tileGroupElement1.RowsCount) / 2;
     
               tileGroupElement1.PositionOffset = new SizeF(newWidth, newHeight);

    Hello Andre,

    It is not easy to get the actual width of a group element because it is valid only when calling its parent element ArrangeOverride method. However, you can center groups both horizontally and vertically by using a custom RadPanoramaElement and overriding its ArrangeOverride method. Consider the following code:
    public class CustomPanorama : RadPanorama
    {
        public override string ThemeClassName
        {
            get
            {
                return typeof(RadPanorama).FullName;
            }
            set { }
        }
     
        protected override RadPanoramaElement CreatePanoramaElement()
        {
            return new CustomPanoramaElement();
        }
    }
     
    public class CustomPanoramaElement : RadPanoramaElement
    {
        protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(RadPanoramaElement);
            }
        }
     
        protected override SizeF ArrangeOverride(SizeF finalSize)
        {
            base.ArrangeOverride(finalSize);
     
            this.GroupLayout.Arrange(new RectangleF(
                (finalSize.Width - this.GroupLayout.DesiredSize.Width) / 2,
                (finalSize.Height - this.GroupLayout.DesiredSize.Height) / 2, this.GroupLayout.DesiredSize.Width, this.GroupLayout.DesiredSize.Height));
     
            return finalSize;
        }
    }

    If you have further questions, do not hesitate to contact me.
     
    All the best,
