Answer 1

I don't like to answer with links, nor just text, so here is an example of how can you make a div/table or mostly any html container to change it's content.

If you're using MVC with Razor it'd look like this

TestView.cshtml

@using (Ajax.BeginForm("Test",
                       "TestController", 
                       new AjaxOptions {
                           HttpMethod = "GET",
                           InsertionMode = InsertionMode.Replace,
                           UpdateTargetId = "searchResults" }))
{
    Search User by ID: 
    
}

TestController.cs

public class TestController : Controller
{
    public PartialViewResult Test(int id)
    {
        var model = myDbContext.Users.Single(q => q.UserID == id);

        return PartialView("_PartialViewTest", model);
    }
}

_PartialViewTest.cshtml

@model IEnumerable



    @foreach(var item in Model) {
        
    }

    

        
Name
        
Email
    

            
@item.Name
            
@item.Email
        

...and if you want to do it using classic ASP.NET, it'd be like this:

TestPage.aspx

    

        

            Test!
            

            

            
        
    

Scripts.js / TestPage.aspx

function testCall() {
    $.ajax({
        url: "TestHandler.ashx",
        dataType: 'json',
        success: callbackTestCall
    });
};

function callbackTestCall(payload) {
    document.getElementById("ajaxResult").innerHTML = payload;
};

TestHandler.ashx

public class TestHandler : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        JavaScriptSerializer jss = new JavaScriptSerializer();
        Random random = new Random();

        string actualData = random.Next(2001).ToString();

        context.Response.ContentType = "text/plain";
        context.Response.CacheControl = "no-cache";

        context.Response.Write(jss.Serialize(actualData));
    }

    public bool IsReusable
    {
        // Whether or not the instance can be used for another request
        get { return true; }
    }
}
