You can do this by Ajax.

Add reference of “jquery-1.4.1.min.js” or ”jquery-1.5.1.min.js” in your .aspx page.

In below code Javascript function "JqueryAjaxExample" will call Page Load Of Page2.aspx.

Javascript function "JqueryAjaxExampleResponse" will invoke when response will come back from Page2.aspx.

JavaScript

<script language="javascript" type="text/javascript">

     function JqueryAjaxExample() {
         $.ajax({
            type: "GET",
            url: "Page2.aspx",
            success: function (ReturnValue) {
                JqueryAjaxExampleResponse(ReturnValue);
            }
        });
    }
 
    function JqueryAjaxExampleResponse(ReturnValue) {
        alert(ReturnValue);
    }
</script>

Then write your return value to Response in your function as below.

C#

//Page Load of Page2.aspx
protected void Page_Load(object sender, EventArgs e)
{
    ReturnValueFunction();
}

private void ReturnValueFunction()
{
    string ReturnValue = "SomeThing";
    Response.Clear();
    Response.Write(ReturnValue);
    Response.End();
}
