New in v2.0

• Support for Multiple Columns
  Developers can now define any table structure and it will be applied to all combobox items. The key benefit here is that this is achieved using templates. Table structures can be easily customized and modified on the go, without the need to recompile or code anything.
  Multi-column mode supports all advanced AJAX features of the combo – load on demand, auto-complete, etc. Items loaded on demand are automatically formatted using the templates as well.
  
  
  　
• Column Headers
  Headers are especially useful in multi-column mode (though they can be used in any other combo mode as well). You can use the header to assign column titles for each combo column. The header does not scroll when items go up/down and is always visible – end-users can easily associate column data to its respective column title in the header. Headers are also defined using templates and you can have any content there, even images.
  
  
  
  　
• Enhanced end-users restriction policies
  You can now control whether end-users can enter text that is not predefined in any of the combobox items. All you have to do is set the AllowCustomText property. By default it is set to true, i.e. typing is allowed. If the AllowCustomText property is set to false the input for the combobox is restricted only to match the strings present in the combobox items.
  
  
  
  　
• Multi-item Autocomplete
  r.a.d.combobox now supports multiple autocomplete using any delimiter (";" , ",", etc.) just like in Microsoft Outlook®.
  
  
  
  　
• AJAX mode with external streamer page
  For complex load-on-demand scenarios, when combobox is added dynamically to the page or is not initially visible, you can use ExternalCallBackPage. ExternalCallBackPage is a normal ASP.NET aspx page that contains only one instance of r.a.d.combobox. The ID of this instance should match the ID of the combobox initiating the request. You can then wire the ItemsRequested event handler of the external combobox and write your custom logic, the same way you would do in the original page. Finally, set the ExternalCallBackPage property of the original combobox to the name of the callback (streamer) page. The path is relative to the current path of the parent page (e.g. no path needed if the streamer page is in the same folder - just the name of the file).
  
  　
• Nested Declarative Data Binding
  When r.a.d.combobox is used as a template for data-specific ASP .NET controls such as GridView, DetailsView, or r.a.d.grid, you can have the combobox show the currently selected value for the column where it is nested on the current row. You can easily do that using the Edit DataBindings option of the r.a.d.combobox Smart Tag.
