You can use OnSubmit form event, and javascript to copy data from TextBox to the hidden field. Here is a simple html exmple:
<html>
<head>
<script type="text/javascript">
function AddDataToHidden()
{
document.getElementById('test').value = document.getElementById('login').value;
}
</script>
</head>
<body>
<form action="action.aspx" onsubmit="javascript:return AddDataToHidden();" method="get">
<input type="text" id="login" name="login" />
<input type="hidden" id="test" name="test" />
<input type="submit" />
</form>
</body>
</html>

For best usage you can change document.getElementById('test') to jQuery selectors, if you are using jQuery.
Why a hidden field?
Why can't you simply pass the Value of the TextField using jQuery's OnButtonClick handler?
Below is the JavaScript code:-
$(document).ready(function(){
$("#Create").click(function(){
var data1 = $('#TextField').val();
$.ajax({
type:"Post",
url:'/Controller/SomeFunction',
data:"Name="+ data1,
success:function(result)
{
alert(result);
},
error:function(result)
{
alert("fail");
}
});
});
});

Why do you need a hidden field for that? If you have a textbox, then on form submit, the value from the textbox will be directly available.
I might not understand you correctly, but from what it looks, your textbox's value will always have the same value as the hidden one..
What exactly are you trying to accomplish then?
