Ajax Control ToolKit

 

Ajax Control Toolkit has many controls and extenders. Extenders are the ones which enhance or extends the functionality of other controls. Ajax Toolkit is an open source. Anyone can download it , use it and can contribute code to it to add additional functionality.

This toolkit can be downloaded from here:

It is not a part of Visual Studio , so we need to download the library(.dll file) and add it to visual studio. Ajax Control Toolkit can only be added to Visual Studio Version 2008 and above.

To add Ajax Control ToolKit to Visual Studio , Check my article on How to Install ASP.net AJAX Control ToolKit

Asp.net Ajax Control Toolkit Extenders:

These are the controls which extend the functionality of other controls. Asp.net validator’s are good examples for extenders. For example consider “RequiredFieldValidator” , it is associated with the Textbox and extends the functionality of textbox to check whether it has value or not. If it does not have value it prompts user. Likewise Ajax Control Toolkit extenders are used to enhance the functionality of other controls and change their behaviour.

ToolkitScriptManager:

As ScriptManager is used to handle script for Ajax Controls , we need to use “ToolkitScriptManager” for Ajax Toolkit Controls and extenders. It is derived from the base Script manager to handle scripts.
