Most effective method for performing partial updates to content in ASP.NET

My initial plan was to utilize a master page for every page within my application. However, I soon discovered that every time the page changed, it would reload the full page even if it had the same master page. I realized I had confused the frameset with the master page concept. As a result, I came up with two alternative ideas to achieve the desired outcome without using a master page.

  1. The first idea is to use an iframe and set the attribute to runat server, allowing me to change the page in the codebehind. This approach appeals to me because I prefer to control the page flow on the server side.

  2. Alternatively, I could make each individual child page a user control and dynamically load it into the panel in the codebehind.

I would appreciate some advice on which method is best in ASP.NET with AJAX enabled, or if there are other better alternatives available. Thank you.

Answer №1

The utilization of a Master page proves to be highly beneficial, particularly when it comes to housing elements such as headers, copyright text, and menus that remain consistent across various pages within a website. Disregarding them would only lead to regret once modifications need to be made to the overall site layout.

In response to your inquiry, integrating AJAX is a fantastic option. Additionally, contemplating a straightforward transition to ASP.NET MVC can substantially simplify your work process and resolve many challenges by prompting you to structure your pages based on Views and data insertion according to Actions.

Within the master page, contentplaceholders are provided for the specific content each individual page will contain. You have the ability to establish a default menu in the masterpage and subsequently override it on selected pages.

Menus present a unique situation where their display often varies depending on the current page being viewed. If the logic governing these changes is relatively uncomplicated, considering placing the menu within a UserControl (ASP.NET) or View (MVC) could offer a solution, allowing the control/controller to determine the necessary data to include in the menu for user presentation.

In terms of full page reloads: the integration of AJAX eliminates the need for a complete page refresh. Furthermore, with MVC, the absence of viewstate and lighter markup reduce concerns surrounding full page loads. Consider inspecting Stack Overflow's markup - an example of an MVC site. Although avoiding full pageloads whenever possible is preferable, AJAX facilitates this process. MVC simply diminishes the impact of full page loads.
