How to Update a 开发者_如何学编程div tag in Master Page using a button click in Content page? or Wise versa

Do you get the data to be updated in a postback only? You can either do it using javascript if you get the data to be updated in the client side, or bring it to the client side on a postback and use some javascript method to update. If you get the data as some attribute of a server side class, ou can use server tags (as in classic ASP) in the master page like <div id="updatableDiv"><%=myClass.PropertWithUpdatedValue%></div> in the master page.
