Is there a way to refresh a different webpage within the current session?

In the world of Asp.Net 4, there is a form waiting to be filled with numeric data by the customer. However, this task can sometimes prove tricky as customers may struggle to calculate and input the total figure for each of the four fields.

An innovative solution is being considered - the addition of a calculator link that would lead the customer to another page where they can input all the minor numbers to find the total. The challenge lies in enabling them to save the total figures and then transfer them back to the original page seamlessly.

The possibility of using Ajax/javascript or sessions to keep track of the figures has been pondered, but uncertainty lingers.

If you have any insights on how this can be achieved, your guidance would be greatly appreciated.

How about this idea?

  • Saving the values to the Session and then refreshing the parent window when closing the child window (the calculator). More details on this can be found in a related question. You can use the code provided in that question:

To open the window:

window.open("foo.html","windowName", "width=200,height=200,scrollbars=no");

To refresh the parent form from the child window:

 <script>
       window.onunload = refreshParent;
       function refreshParent() {
           window.opener.location.reload();
       }
 </script>

  • Alternatively, you could also skip using the Session and directly set the values from JavaScript in your child form. After opening the child window with window.open();, consider implementing something like the following:

    <script language="javascript">  
    function UpdateParent() 
    { 
        window.opener.document.getElementById('MyControl').value="New Value"; 
    } 
</script>
