Using AjaxPro in ASP.NET to achieve interaction between the front-end and back-end mainly involves the following steps:

  1. Introducing AjaxPro library: First, download the AjaxPro library and add it to your project. You can search for AjaxPro in the NuGet package manager and install it.
  2. Create backend method: Generate the necessary interactive methods in the backend code and include the [AjaxPro.AjaxMethod] attribute on the method.
[AjaxPro.AjaxMethod]
public string GetHelloWorld()
{
    return "Hello World!";
}
  1. Register AjaxPro service: Register the AjaxPro service in the Application_Start method of the Global.asax.cs file.
AjaxPro.Utility.RegisterTypeForAjax(typeof(YourClassName));
  1. Invoke backend method from frontend: Use the JavaScript methods provided by AjaxPro in the frontend page to call the backend method.
AjaxPro.YourClassName.GetHelloWorld(onSuccess, onError);

function onSuccess(result) {
    alert(result);
}

function onError(err) {
    alert(err.get_message());
}

By following the steps above, you can achieve interaction between the front end and back end. The front-end page can call backend methods and handle the returned results through JavaScript. The AjaxPro library offers abundant functionalities and methods to facilitate the interaction between the front and back end.
