1- Add name to your inputs like this :
code :
<form name="myForm" id="myForm">
<input id="infoID1" name="mycheckboxid[]" type="checkbox" value=1/>
<input id="info1" name="mycheckboxvalue[]" type="text" value="something good"/>

<input id="infoID2" name="mycheckboxid[]" type="checkbox" value=2/>
<input id="info2" name="mycheckboxvalue[]" type="text" value="something bad" />

<input id="infoID3" name="mycheckboxid[]" type="checkbox" value=3/>
<input id="info3" name="mycheckboxvalue[]" type="text" value="something ugly" />
</form>
$.ajax({
    url: "workingPage.php",
    data: $('form#myForm').serialize(),
    type: 'POST',
    success: function (otherData) {
        $(doStuff);

To fix this issue You may get the named TextBox by means of the FindName method:
code :
private void click(object sender, RoutedEventArgs e)
{
    var button = sender as Button;
    var parent = button.Parent as FrameworkElement;
    var textBox = parent.FindName("textbox1") as TextBox;
    button.Content = textBox.Text;
}

This might help you I need to get id of dynamically created div when I hit a key in dynamically created input inside that div. I create them at same time after clicking button: , Put them both in the same click function and put the num outside like
code :
$(document).ready(function(){
var num = 0;

$("#create").on("click", function(){

    $("#known").append("<div id='unknown_" + num + "'><input type='text' class='get_id'/></div>");
    num++;

    $(".get_id").on("keypress", function(){
        var id = $(this).parent().attr("id");
        alert(id);
    });
});
});

Hope this helps NO the previously allocated memory will not be freed. You will lose all allocated memory.
By overwriting your persons pointer, you lose your handle on the allocated storage. So before you do this, you have to call
code :
::operator delete(persons[0].pets);
::operator delete(persons[1].pets);
::operator delete(persons);
#include <vector>

struct Person {
  std::vector< Pet > pets;
};

std::vector< Person > persons(2);
persons[0].pets = std::vector< Pet >(2);
persons[1].pets = std::vector< Pet >(3);

persons = std::vector< Person >(3); // won't lose memory

To fix this issue You'll save yourself a lot of headache in future if you do things properly and use data-binding instead of manipulating the GUI elements directly, but if you insist...
You need to use the Visual Tree Helper to traverse the control in order to find the templated framework element. You may also may need to call ApplyTemplate first to make sure that your control has been templated and is ready to access:
code :
yourTemplatedControl.ApplyTemplate();
var canvas = VisualTreeHelper.GetChild(yourTemplatedControl, 0) as Canvas;

var ellipse = new Ellipse();
ellipse.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
ellipse.VerticalAlignment = System.Windows.VerticalAlignment.Top;
ellipse.Width = 50;
ellipse.Height = 50;
ellipse.Margin = new Thickness(0, 0, 0, 50);
ellipse.Stroke = Brushes.Blue;
ellipse.StrokeThickness = 1.5;
ellipse.Fill = Brushes.Yellow;
canvas.Children.Add(ellipse);
