Right now I am using ng-datatable for displaying data in a table, but I want to write a custom directive to display data in a table grid.
I'd recommend going to another site for the tutorial on creating a directive/component. Nothing really beats the AngularJS site itself, but there is a ton out there. For directives AngularJS Directives, for components AngularJS Components. Considering web components are more robust than directives I would recommend going the path of the components.
For example:
You can split your grid into many different factions for modular/reusable components throughout your project. Create a component for your header, a single row (pass each record from your collection into the row component), a pagination component, filter/search component, etc.
Good luck on your endeavors.

I have a HTML table inside my react application. Now I have a requirement to resize my table columns by raging on the column header. Found lots of react solutions by searching on the web but almost all of them are with a table component(Ex. React Table, RC Table, React Grid).
I am looking for a pure react solution to integrate with my existing Table. Found lots of jQuery libraries but it is not recommending to use jQuery with react.
If I go for a pure java script solution will it create a conflict with the actual DOM and React DOM since pure java script directly changing the actual DOM?
Anyone have a working sample with react or any recommended way to go ahead?
Well, I have never used and never felt like that I should use the UI router. I was asked in one of the interviews about this and so felt like reading if I am missing something out as an AngularJs developer.
Now, the explanations on internet displays it's strength based on the modularity and reusability of the components. Nesting of views etc.
If I want to reuse components in my view, then can't I use directive instead of a new state? According to this article by scotch.io(top google result) for ui router we can use separate data /controllers in my view. Well, can't I do the same via directive's controller and template. I can still reuse as many times as I want it.
Please let me know if I am missing some cool feature and makes it quintessential to use it in an AngularJs application (yeah a larger one with lots of reusable components of course) .
The whole point of the router is that it uses the URL to change states. If you just used directives, you would have to write your own mechanism for syncing up URLs with specific directives.
AngularJS is a framework for Single Page Application.
Single Page Application (SPA)
Single Page Application is a web application that loads single HTML page and dynamically updates a fragment in the page as the user interacts with the app.
John Papa's blog explains SPA in simple terms.
The biggest advantage of SPA that I see is
once the application is loaded, the state is maintained without
requiring server roundtrip when user navigates.
Users can bookmark deep link into your application. SPA framework (AngularJS) will take care of loading the required state when user open bookmark.
Although it is technically possible to achieve the above in a non-SPA application, it was never as simple as SPA.
SPA is useful for highly complex applications with many pages. For simple applications with 2-3 pages jQuery is the way to go.

You probably know all these and I think you are trying to achieve SPA using directive.
Routing
Routing framework loads a view dynamically based on user action into the main page without refreshing the whole application; providing SPA effect.
There are two popular AngularJS routing frameworks available.
ngRoute
UI-Router
ngRoute is based on URL mapping and UI-Router is based on state name mapping. I prefer UI-Router.
Routing vs Directive
Now, the explanations on internet displays it's strength based on the
modularity and reusability of the components. Nesting of views etc.
Yes directive is used for modularity and reusability and can load views dynamically but cannot choose a view dynamically based on user action. You have to write complex conditions within directive to choose a view dynamically.
For example, if you have an application with 3 links and you need to show a view based on the link user clicked.
Using directive you need to keep track of what the user clicked and write a mucky condition to choose a view to display. Most of the time you will fail to achieve the effect because the link can be accessed in multiple ways.
On the other hand, once routing is configured, the corresponding template will be dynamically loaded when user clicks the link. It is way easier to change the view based on user action.
Another advantage. When user opens a bookmark deep linked into the application, routing framework will take care of loading the sate (It is impossible to achieve this using directive). It feels more natural way of designing an application.
Choice is yours.
I am trying to create one html page using AngularJs with multiple views. And each view have nested states. When I am trying to use two view with nested states. It's only displaying one. Please tell me if I can use any particular steps or any link. It will be really helpful.
I have folder structure like shown in the attached imageFolder structure.

I'm generating a dynamic number of Google Charts tables after receiving the content through an ajax request and I wanted to apply an accordion effect on them. I wanted to know if I could do that with directives (since if I just code render the angular tags they won't get interpreted).
I don't need a code example, just a short answer to see if I should learn directives or if I should do it in a different way (I was thinking routeParams).
Thanks!
A directive is an equivalent of a jquery plugin, it should be use when you want to create a widget which manages some user interactions or a specific templating.
In your case it's a great idea, the directive could call a service which shall return the server datas and could manage all user interactions like open and close the accordion.
Before all, think about reusability.
First of all i am confuse for my project whether it can use angular.js or not, although i have started using it and i created some customization module with this but when i started applying it for all project i got stuck on many things.
My project is a order taking project and it has structure like this.
In the index page it has 3 panels.
left panle that draws all categories
middle panel that draws all category specific productes
and right panel that draws all the basket items with calculations.
On product click there also appears a model that draws all the customization.
I am using MVC-4.
Every thing on index that includes some layout is a partial view _leftpanl, _middlePnl, _rightPnl, _customziaion.
My concern is.
If i define the routes to the module i created how to fix on ng-view because per scope there will be one ng-view only. and my application load atleast 3 partial views to index page at the same time. So how would i fix on ng-view.
Just gimme some guide lines that i should follow to create this kind of application with angular.js.
Or it is not possible with angular because i think it is not a single page application.
Use the Angular-Breeze SPA template provided by the ASP.Net team http://www.asp.net/single-page-application/overview/templates/breezeangular-template
Don't mix up the Razor view/partials with Angular. Use ASP.Net MVC to manage only the REST interface and use AngularJS to embrace the presentation layer.

It seems you have a problem to define what you really need.
AngularJS primary purpose is to do some Single Page Application. Which is, code only in HTML/CSS/JS in the front-end, and reuse your abilities in the back-end to produce DATA only (REST-json is the most classic but you can choose whatever you want).
So if you use a tool outside its primary purpose, you have to do some compromises : Of course you can mix backend template with AngularJS, but in this case, you can forget the router and ng-view.
Use AngularJS if you think you have some complex web interface. If it is only some static text, or even a few input forms here and there you don't necesseraly have to AngularJS, you can just use your classic server-side display rendering.
You could use ng-include to include each of your three partials into one view. Then in each partial view you can specify the controller with ng-controller. For creating the modal popup I would probably use ui bootstrap's modal
Alternatively you could use ui-router to create multiple parallel views.
I have following guidelines here which i hope will help you.
Do not mix Server Side MVC and Client Side MVC. AngularJS is primarly meant to augment the HTML and browser capability. The two-way binding of angularjs is excellent and provides lots of dynamic behavior. MVC4 scores best when we have to do lot of server side processing using the .Net platform capabilities.
But as you spent some good effort on this project and the corresponding technologies, there is a way out. Convert all your Controlller Actions in MVC4 to produce JsonResult and when the angularjs needs data use that, e.g. in $http.get( .
