FYI - I cannot click into this WYSIWYG box with IE 8

Anyways, on the main asp.net page is a bing search box. When you type in a search term it displays a very complex composite drop down menu. I am looking to do something very similar so I was wondering what tools / Technology was being used there.

I was wondering if there are any tutorials or "How To's" on building just that sort of composite drop down menu. Right now I am looking into the jQuery, JSON, ASHX route but would appreciate any useful technologies to make things easier. Thanks for any input.

Use Ajax AutoComplete Extender

or

ComboBox

Not sure if you are seeing something different than I am. The drop down menu I am refering to is a complex composite control menu that looks like this:

You can use AutoComplete from AJAXControlToolkit

I'm not looking for an auto-complete combobox. As you can see from the image above, the drop down menu is a complex tabbed and paged composite control menu.

 Hi,

There is not a available control. You can make a ModalPopup to show the information. You can define onchange event for textbox. When you click the button, it will call the web service with the value the user typed. In callback function, you can build a Panel to present the result.

The other way is you can use AutoCompleteExtender and do something to change the style of displaying. You can append an additional field to indicate "asp.net","asp.net blog" or other classifications on each item so that you can pass the list from serverside web service to the client. On client, you need custom the list panel to prensent these classifications.

Please check any one of these article to custom the AutoCompleteExtender.
