ASP.NET Ajax Toolkit

The ASP.NET AJAX Control Toolkit is an open-source project hosted on CodePlex. It is built upon the Microsoft ASP.NET AJAX framework and offers a collection of controls that are specifically designed for ASP.NET Web Forms application development. These controls are created with the intention of being familiar and easily utilized by ASP.NET Web Forms developers.

With the Ajax Control Toolkit, developers can utilize the power of Ajax in their ASP.NET Web Forms applications. This toolkit simplifies the process by allowing developers to drag and drop the Toolkit controls from the Visual Studio Toolbox directly onto an ASP.NET Web Forms page. This visual approach streamlines the integration of Ajax-enabled functionality into the application, enabling developers to enhance the user experience without requiring extensive coding or technical expertise.
