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,
