## Downloading Ajax Control Toolkit

You can download Ajax Control Toolkit from the [NuGet Gallery](https://www.nuget.org/packages/AjaxControlToolkit/). The latest version at the time of writing this article is 20.1.0. You can also use the Package Manager Console in Visual Studio to install the toolkit by running the following command:

Install-Package AjaxControlToolkit
“`

After you download or install the toolkit, you need to unblock the AjaxControlToolkit.dll assembly file. To do that, right-click the file, select Properties, and click the Unblock button.

## Adding Ajax Control Toolkit to the Toolbox

The easiest way to use Ajax Control Toolkit is to add it to your Visual Studio toolbox. That way, you can simply drag and drop the toolkit controls onto your web pages. To add the toolkit to the toolbox, follow these steps:

– Create a new ASP.NET Web Forms project or open an existing one in Visual Studio 2017.
– Right-click the Toolbox and select Add Tab. Name the new tab as Ajax Control Toolkit.
– Right-click the new tab and select Choose Items.
– Browse to the location where you downloaded or installed the AjaxControlToolkit.dll assembly and select it.
– Click OK to add all the toolkit controls to your toolbox.

## Using Ajax Control Toolkit Controls

Now that you have added the toolkit to your toolbox, you can start using its controls in your web pages. For example, you can use the AutoComplete control to provide suggestions as the user types in a text box. To use the AutoComplete control, follow these steps:

– Drag and drop a TextBox control and an AutoCompleteExtender control from the toolbox onto your web page.
– Set the TargetControlID property of the AutoCompleteExtender control to the ID of the TextBox control.
– Set the ServiceMethod property of the AutoCompleteExtender control to the name of a web method that returns a list of suggestions based on the user input. You can create this web method in your code-behind file or in a separate web service class.
– Optionally, you can set other properties of the AutoCompleteExtender control, such as MinimumPrefixLength, CompletionInterval, CompletionSetCount, etc., to customize its behavior and appearance.

Here is an example of a web method that returns a list of countries based on the user input:

“`csharp
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public static string[] GetCountries(string prefixText, int count)
{
// Get all countries from a data source
var countries = GetAllCountries();

// Filter countries by prefixText
var filteredCountries = countries.Where(c => c.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase)).Take(count);

// Return an array of filtered countries
return filteredCountries.ToArray();
}
“`

Here is an example of how the AutoComplete control looks like in action:
