The GridVIew has a Resize Event, is that of any use?

(i'm no way an expert, just thought I'd offer a suggestion)

Hello Guy,

There is no dedicated event for this case. You should create a custom detail view cell in order to get access to the child GridTableElement. Please consider the following sample:
void radGridView1_CreateCell(object sender, GridViewCreateCellEventArgs e)
{
    if (e.CellType == typeof(GridDetailViewCellElement))
    {
        e.CellType = typeof(CustomDetailsCell);
    }
}
 
public class CustomDetailsCell: GridDetailViewCellElement
{
    public CustomDetailsCell(GridViewColumn column, GridRowElement row)
        : base(column, row)
    {
    }
 
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(GridDetailViewCellElement);
        }
    }
 
    protected override GridTableElement CreateChildTableElement()
    {
        GridTableElement tableElement = base.CreateChildTableElement();
        tableElement.RadPropertyChanged += new RadPropertyChangedEventHandler(tableElement_RadPropertyChanged);
        return tableElement;
    }
 
    void tableElement_RadPropertyChanged(object sender, RadPropertyChangedEventArgs e)
    {
        if (e.Property == RadElement.BoundsProperty)
        {
            Console.WriteLine("Child view height: " + ((Rectangle)e.NewValue).Height);
        }
    }
}

Could you please describe in greater detail what you want to achieve? This will help us to focus on the issue and provide you with accurate support.
