title: asp.net webforms reusable page design
body: <p>I need design ideas for a webform project I am working on. The public side of the project is complete with a bunch of ASPX pages in a as usual master page. Now I need to create the admin side of the project where the admin staff can load the pages such that they are looking the client page all "framed" in a master page that has number of filter/search controls to get to the right client page. I want to reuse the markup and code-behind I've already created for the client side. </p>
  
  <p>In the old days I would have created a frameset with the admin side controls in the top-frame and the client pages in the bottom frame. It all worked out fine then, but as we know, frameset are not supported in html5. What is the alternative you suggest should be the best way to achieve this goal in the Webforms way of doing things. </p>
  
  <p>I know that there may be some use of Usercontrols somewhere in the solution, but I don't know how exactly this will all come together. If there are any best practice solution out there then please inform me of them.</p>
  
  <p>Thanks.</p>
