title: ASP.NET: How do I navigate to a page after clicking a checkbox?
body: <p>I have some <code>checkboxes</code> and a <code>dropdownlist</code> when the value changes I want to refresh the page while passing the new value.  I tried using <code>autopostback</code>; however, the value is already in the url previously so when the postback occurs the value never changes.</p>
  
  <p>Example:</p>
  
  <p><code>CurrentPage: page.aspx?tab=Home&amp;checkbox=True</code></p>
  
  <p>Then I uncheck the checkbox so I want it to go to the following page...</p>
  
  <p><code>IntendedPage: page.aspx?tab=Home&amp;checkbox=False</code></p>
  
  <p>But instead I the autopostback gives me this page...</p>
  
  <p><code>DestinationPage: page.aspx?tab=Home&amp;checkbox=True</code></p>
  
  <p>Because, I handle the building of the url through a function on my page.  Perhaps I'm doing something wrong by this point.  If so I'd be happy to be corrected on my current setup.  What I think I need to know though is how to load a custom URL on the checkbox.checkchanged event.  I hope this made sense, if not let me know I'll try and clarify it. Thanks!</p>
