I already have a backend prepared, which stores data with datatypes, attributes etc. All the present frontend is done on Backbone.js. Need to convert my Add Field button click UX to a kind of Drag and Drop and graphical visualisation.
I have tried to make the Workflow Builder on my own using the present backend on BackboneJS as we have an SPA Webapp. Had some plans ready, but it is going to take a lot of time. Hence searching for a ready-made workflow code that I can tweak with.

I need to develop a small application integrated in sharepoint. I am using the 2019 version on on premise. The application consists of data entry, sql queries for loading data into the fields. I want to use the latest approaches for this purpose. I still have time, but I don’t know which way to go.
I looked at a lot of solutions without code, but as I understand it, I need to move in the direction of JS, at the same time I want to save it in sharepoint lists or where to store the entered data. But how can I get data from the external MSSQL database, use node.js or the web part, REST. I am very confused, help me please. I developed applications on C # windows form with ado.net, if I know the direction I will figure it out in JS.
So following up with the comments, you could implement the following stack:
React or Vue: To implement a simple GUI to perform basic CRUD on you DB
NodeJS: To handle the data manipulation (if any) and push things to Sharepoint
Take a look at the very popular MERV stack for inspiration on the app structure. (MERV uses MongoDB, but the logic would be the same if you swap that bit for MySQL)
Using NodeJS you can leverage Sharepoint REST API using the available libraries. Check out this tutorial for details on the implementation.
I recently added a roles/permission functionality to a somewhat old web forms app in ASP.NET and C#. Now I need two simple functions: add/edit roles, add/edit permissions to roles (permissions are in a table but not modifiable). The tables are somewhat like this (I need an interface for the bold ones):
Roles table: RoleID, RoleName
Permissions table: PermissionID, PermissionName
Roles_Permissions table: RoleID, PermissionID
How can I make them interactive, in the sense of not having a post-back, and having both functionalities in the same page? I visualize a dropdown for the Roles, that when one is chosen, the list of Permissions refreshes for that role, and right there the user can change the permissions, RoleName, or even add/delete a role. The page needs to use an existing master page to match its appearance to the rest of the web app; I do not know if that would limit functionality.
I need the implementation to be as non-intrusive as possible (no strange plugins, and work with current browsers without any configuration on the client side). I found breeze, knockout and angularjs, but can't find if/how I can add the functionality to an ASP.NET C# Web Forms in Visual Studio 2012 (version 11).
What is the fastest/easiest way to build the page, that will be easily maintainable in the future, and be a good starting point to begin "modernizing" the rest of the web app based on it?
You can add a standard blank aspx page to your application and get it working as normal for a Web Forms application. Wire up the navigation, make sure that it picks up your master page (if you are using one), etc.
From here, depending on various circumstances, you can do a couple of things.
ASP.NET AJAX
This was originally introduced for ASP.NET Web Forms, and uses Web Forms controls and a small amount of work in the codebehind to glue everything together. It's less flexible than other solutions, but should be fine for the scenario you cite. This would be the preferred method if you are more comfortable with Web Forms than other programming models. Policies or the structure of the existing application may also make this more preferable.
Single Page Application
You mentioned frameworks such as breeze, knockout, and Angular. So, let's focus on those. Again, depending on your experience, and the app, these might be compelling options. I wouldn't go as far as Angular for the time being, since it's more appropriate for a full rewrite. It could work embedded in another application, but is probably too much work for the scope of your project.
At minimum you could make do with plain JavaScript and AJAX, but you'd need to write a lot of your own code. If you add in a little jQuery, that will help with DOM manipulation and AJAX calls to your services. I've had success in enhancing older apps with jQuery for DOM manipulation, and Knockout for databinding. You can probably make do without jQuery, but I wouldn't. These two libraries don't make any assumptions about the environment that you are using them in, and should be content to be constrained within the limited scope of a single page within a larger application.
I work for a medium sized company that has an application used by a few thousand people and is built primarily with HTML,Javascript, aspx, xml, xsl, and runs on IE 11. This application is proprietary and not designed in house but we have access to the code for possible modifications and its just sitting out there on the server(s). A new project has come down the pipline for an enhancement\adjustment to be made to a particular area of the application and I'm wondering what kind of web framework I could use to do this work. I am really just needing to call an enterprise service and get data back, display it, and that's about it, so its not incredibly hard. I am worried though about how to integrate it with the existing application.
I am not sure how this scenario would go:
User navigates to page A inputs data, I want that data to go to a controller or something I built, fetch info and send it back to page A. I was thinking of using Spring MVC but not sure. Any feed back or suggestions would be greatly appreciated! I know this question doesn't include code, so please don't hate me.
Thank you.
From a very high point of view and with no knowledge about any specific requirement.
If you have already an application developed in ASP.NET, it's better that you continue the development of the new module of the application on the same platform.
If you want to develop a new module (actually a new web app) that looks like the old application but with a totally different platform like Spring MVC (could use any other), you can reuse the existing css styles and databases.
For integration purpose you could modify the original application in the menu(or links) that redirects you to the new module and implement a single sign on server (this will required work on both applications) to made the transitions smoothly between both applications (something like a portal style). Note that they will have a different context application path.
I'd like to build an application(s) with rich ajax-based user interface. Key UI features would be:
Realtime data saving (incomplete data that user typed in forms should
be saved server side)
Realtime validation (fields should be validated, sometimes validated using server side
check, when lost focus)
Handling URL navigation (with URL # fragment) and browser back
button
No page reloading
So in general I'd like the kind of UI like in google applications, wunderkit, asana.
My application will have a lot of forms, lot of input fields and will have to deal with lot of data including file uploads. The previous version of the application use ASP.NET-MVC3 and ajax is used only in form of few dedicated modules.
The requirement is to build it in .NET and I can't image using anything else than ASP.NET-MVC.
The question is: Is there any decent framework for building such appliactions with .NET MVC 4 or should I rather start building it myself?
UPDATE:
I know there's lot of jQuery plugins for each of ajax UI features. I'm looking for some kind of base for rich ajax applications where these plugins are already chosen. Although I'm starting to realize that maybe creating this base by myself is a better idea.
Sometimes it's not "invent the wheel again" out there exist so many javascripts libraries to help you. the level of abstraction you're looking for, you don't find something, at least good.
I always do custom libraries who adapts to the design and keeps the pattern who wants the client to re-use (DRY), remember that not everybody wants the same user interface flow
Just about everything you're asking about can be found in a jQuery plugin.
I'm looking to create a cross platform Mobile App and have been looking into Developing using PhoneGap. I'm an amateur programmer and most of my knowledge is in ASP.Net and C#.
Will only being able to use HTML, CSS and Javascript with PhoneGap limit me to specific functionality of my App? and would migrating to HTML5 help in adding more functionality to an App?
I'm looking to be able to Populate Drop-Downs from a Database, Add/Edit/Delete Items from a Database, Create Reports Ect...
Your only real limitation as far as data access goes is that you're limited to an SQLite database, which to be honest isn't much of a limitation since it performs great for single-user access.
The short of it is that you have access to a database from within your app, so you can do whatever you need to. The tools are HTML & JS as opposed to C# with some graphics layer, so doing things like creating graphs is quite different, but it's all possible.
Also note that depending on what your app is doing, PhoneGap is one of several solutions. If you want a "native" look/feel, consider TitaniumUI -- it takes common code (still JS) and pushes it through some translation layers to create native UI components.
