This method is responsible for showing localization icons next to every control that has localizable properties.

The icons are resource based and also display the control's ID. Note icons are placed only next to any controls that are marked as [Localizable]. Some contained controls like GridVIew/DataGrid Columns are not marked as [Localizable] yet the ASP.NET designer creates implicit resources for them anyway - these controls will not show icons.
