If ColumnVirtualization make so problems, why do you need it? You can do a several improvements, but they can't solve the problem completely.

1. Change TextBoxes for light-weight objects:

   public class TextItem
   {
       public string Text { get; set; }
       public Brush Background { get; set; }
       public Brush Foreground { get; set; }
   }
   
   
   public class Row : ObservableCollection
   {
   }
   

2. Enable VirtualizingStackPanel: dg.SetValue(VirtualizingStackPanel.IsVirtualizingProperty, true);

3. Replace styles with templates:

       for (int i = 0; i < 100; i++)
       {
           DataGridTemplateColumn column = new DataGridTemplateColumn();
           column.CellTemplate = (DataTemplate)XamlReader.Parse(
               "" +
                   "" +
               "");
           column.Header = "Column " + i;
           dg.Columns.Add(column);
       }
