I want to take the data from Textbox1 and put it in a JSON and then read the the data in a [Web Method] of a c# program. I am just using this as a learning example for later projects.

I would like to advise you to use Newtonsoft.JSON library to work with JSON data. I like it myself, example code

C#

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}";

Movie m = JsonConvert.DeserializeObject<movie>(json);

string name = m.Name;
// Bad Boys
</movie>

You can get more information and resources from the website, or you can always ask questions if you get into trouble.

JavaScript

$("#<%= Button1.ClientID %>").click(function () {
  var url = '@Url.Content("Default.aspx/LoadUserControl")';
            $.getJSON(url, { passedtext:$("#<%= TextBox1.ClientID %>").val() }, function (data) {
})
})

now add this

C#

public static string LoadUserControl(string passedtext)
        {
         //in the passedtext there will be the value of text box and what ever you want to do with this you can do
  
        }
