Answer 1

you can get the value of this text box using javascript and save it in hidden field as comma separated then read the hidden field value from your action method(I am using jquery)

var AllTextBoxesInPage = $('input[type=text]');
var AllValues='';
AllTextBoxesInPage.each(function(index){
   if(index==0)
   {
    AllValues+=',';  
   }
   AllValues+=$(this).val();
});
$('#HiddenFieldID').val(AllValues);

in your controller class

public ActionResult MyAction(FormCollection MyForm)
{
   String AllValues =MyForm["HiddenFieldName"];
   String[] SeparatedValuse = AllValues.Split(",");
}
