Try something like.

On the client....
<form name="frmForm' action='default.asp'>
<input type="text" id='txtName'/>
<input type='button' onclick='jscript:changeTextbox();'>
</form>

<script language='JScript'>
function changeTextbox()
{
txtName.value = 'hello wolrd';
frmForm.submit;
}
</script>

On the server....
Use the event on the button, to change the property of the text box.
