Ajax Control Toolkit
The Ajax Control Toolkit contains a rich set of controls that you can use to build highly responsive and interactive Ajax-enabled Web applications. The Ajax Control Toolkit contains more than 40 controls, including the
AutoComplete,
CollapsiblePanel,
ColorPicker,
MaskedEdit,
Calendar,
Accordion, and
Watermark controls. Using the Ajax Control Toolkit, you can build Ajax-enabled ASP.NET Web Forms applications by dragging-and-dropping Toolkit controls from the Visual Studio Toolbox onto a Web Forms page.
To view an interactive Web site that demonstrates each of the Ajax Control Toolkit controls, visit the
Ajax Control Toolkit Sample Site.
