    {
      FieldInfo fieldInfo = control.GetType().BaseType.GetField("userSized",
        BindingFlags.Instance |
        BindingFlags.NonPublic);
      fieldInfo.SetValue(control, true);
      control.Height = height;

Private Shared Sub ChangeDescriptionHeight(grid As PropertyGrid, height As Integer)
  If grid Is Nothing Then

  End If
 
  For Each control As Control In grid.Controls
    If control.[GetType]().Name = "DocComment" Then
      Dim fieldInfo As FieldInfo = control.[GetType]().BaseType.GetField("userSized",
