Creating a Dynamic CRUD Page in a Classic ASP.NET C# Web Forms Application

I recently introduced roles and permissions features to an older web forms application built using ASP.NET and C#. Now, I am looking to add simple functions for managing roles and permissions effectively. The structure of the tables I'm working with is as follows (with the parts needing interface highlighted in bold):

  • Roles table: RoleID, RoleName
  • Permissions table: PermissionID, PermissionName
  • Roles_Permissions table: RoleID, PermissionID

I want to make these components interactive without requiring post-backs, allowing users to handle both functionalities on the same page. My vision includes a dropdown menu for roles where selecting one would dynamically refresh the permission list specific to that role. Users should be able to modify permissions, role names, and even manage roles directly from this interface. It is important for the page to maintain consistency with the existing master page design to align with the overall look and feel of the web app.

The implementation should be seamless and not dependent on external plugins, ensuring compatibility with popular browsers without any additional configurations required on the client side. While tools like Breeze, Knockout, and AngularJS seem promising, it's unclear how they can be integrated into an ASP.NET C# Web Forms project created with Visual Studio 2012 (version 11).

What is the most efficient and straightforward way to develop this page, focusing on future maintainability and serving as a foundation for modernizing other sections of the web app based on these enhancements?

Answer №1

If you're looking to integrate a standard blank aspx page into your application for Web Forms, there are a few steps you can take to ensure everything runs smoothly. Make sure to set up navigation, connect it to your master page (if applicable), and follow the necessary setup procedures.

Depending on your specific circumstances, there are different paths you can take.

Consider ASP.NET AJAX

This option was initially designed for ASP.NET Web Forms, utilizing Web Forms controls and some codebehind work to integrate everything seamlessly. While it may not be as versatile as other solutions, it is suitable for the scenario you've described. If you have a stronger preference for Web Forms or if existing policies favor this approach, ASP.NET AJAX could be the way to go.

Explore Single Page Application Frameworks

You mentioned frameworks like breeze, knockout, and Angular - let's delve deeper into those options. Depending on your familiarity with these technologies and the nature of your project, they could offer compelling advantages. For now, tackling Angular might be more extensive than needed, as it typically suits full rewrites. While it could function within another application, embedding it might require significant effort beyond your project scope.

At a minimum, you could opt for plain JavaScript and AJAX, though this would entail writing substantial custom code. Incorporating jQuery can aid in DOM manipulation and service calls via AJAX. Personally, I've found success enhancing older applications using jQuery for DOM manipulation and Knockout for databinding. While you could manage without jQuery, it's a valuable tool to have. Both libraries can operate effectively within the confined space of a single page in a larger application without imposing any environment-specific assumptions.
