Star column width is not calculated right

Hi,

I want the DetailGrid to copy the columns from the parent. That’s why I create columns in the “DetailsExpanding” Event like this:

        
private void DgCommands_DetailsExpanding(object sender, DetailsExpansionChangingEventArgs e)
        {
            var dc = e.DataGridContext.DetailConfigurations[0];
            if (dc.AutoCreateColumns &&
                dc.Columns.Count() == 0)
            {
                dc.AutoCreateColumns = false;
                foreach (var c in e.DataGridContext.Columns)
                {
                    var col = new Column()
                    {
                        FieldName = c.FieldName,
                        Title = c.Title,
                        CellEditorDisplayConditions = c.CellEditorDisplayConditions,
                        Width =  new ColumnWidth(c.Width.Value, c.Width.UnitType), // Width= "*"
                        VisiblePosition = c.VisiblePosition,
                        IsMainColumn = c.IsMainColumn,
                    };
                    dc.Columns.Add(col);   
                }
            }

        }

That works out so far but the first column has a width of 0 even though it has a star.
Do I have to tell the Grid, that it has to update the columns? How?
Do I have to create the columns on a different position?

Thanks for help
