npm install is not installing and erroring continuosly - ASP.NET Discussion Boards

Perhaps Specifying Validation Groups may be what you need?
[^]

_______________________________________________________________
Ah don't lean on me man, cause you can't afford the ticket

ValidationGroup won't work. I only have one button on my form.

The WebForms validators don't include conditional validation out of the box.

You can write your own conditional validators, or find a library that does it for you. (The only one I've seen is a commercial component, so I wrote my own.)

Or, you can use some code to enable or disable the validator[^] based on a condition.

Otherwise, you'll have to stick with the CustomValidator[^]:

Is it possible to call a javascript function in a cshtml, in the @{} section, and the javascript function is defined in the script section of the cshtml.

Thanks

No, your cshtml is compiled and executed as .net code on the server, the result is that it generates html, that html is then sent to the client browser to be executed and the client browser can interpret and execute javascript. So you can't run javascript in your views as the javascript doesn't yet technically exist.

I have a list passed on to the view from the controller through a viewbag. so if the viewbag has the list, then execute a javascript function that is defined in the script section of the page. what is the other option?

<script type="text/javascript">
    function myFunc() {
        alert('Hello');
    }
</script>

@if (ViewBag.MyList != null)
{
    <script>myFunc();</script>
}

Note the order is important, js is interpreted in order so you can't call functions that have not yet been defined.

Hi,

I am trying to run npm install, I'm not sure what's it, all I doing is following an article to make my application workable with Angular 2.0, but its never stopping giving me errors. I don't know why is so tough to install it.

I have created package.json file, copied the following script init. ABCSolution is my solution name and ABCWebApp is my asp.net mvc application name, I don't know which one should I use for the name there, I putting the Solution Name

I placed them in the Project folder first and ran the npm install from that same folder it gave me errors, then I placed these files in the Solution files, then ran the npm install, never leaving the errors.
I am frustrated and tired, I am not understanding what are those dependencies are what are those versions in them.

Can anybody please help me in this aspect, what went wrong, I really need this help a suggestion, a link or even a code snippet helps me greatly. What's this npm install why is it making my life so tired, I don't know.

And the error that I getting is as below:

Hi,

I created a mvc web project with scaffolding that displays well in the Index page. When I edit, I do not want any of the fields in the edit page to edit. Instead, I added a textbox whose value I calculate and save the rest of the fields to the database. I cannot get this to work, as the model in the HttpPost is null. Please help.

Thanks

Have you looked into any tutorials about doing CRUD in ASP.NET MVC? You should be able get more references in the web. The idea is to send back the model to your action method if your action requires the model on POST request. I would really recommend you to read the basics on how MVC arch works before jumping into the limbo.

Here's an article that may help you understand the basic of ASP.NET MVC: ASP.NET MVC 5: Building Your First Web Application - Part 1[^]

There's a problem somewhere in your secret code. You should fix that.

If you want someone else to help you fix it, then you'll need to share the relevant parts of your code.

Did you wrap the textboxes and submit button in a form tag or element?, so the input elements post back to the controller.

Do you have the proper tools and configuration setup? Have you tried using the latest version of Angular2, Node and NPM?

Yes I do my friend

I need a quick and dirty way to capture information that a person would normally have to type or write into a word document. My challenge is that the person inputting the data needs to be able to key the information online, save the information, print to a pdf/word doc and change the information later.
Is there a quick way to do this? I initially thought using FDF (the old pdf form filler), but i have a few concerns. Any other insights would be greatly appreciated. Thanks.

Not sure what you are looking for. One quick way is to build the page and write the code. What exactly are you looking for?

There are two kinds of people in the world: those who can extrapolate from incomplete data.

There are only 10 types of people in the world, those who understand binary and those who don't.

i want to capture information from a user via a webpage, but I want to use something that is highly configurable as the user will want to create different pages to collect information. We have a document assembly program which works great internally, but we need a flexible solution that can work externally. the document assembly program is expensive if we attempt to allow external users to interface with the application so we're trying to find an alternative custom coded program.

Thinking a bit outside the box here, but what about using something like SurveyMonkey? They have a free plan if you just want simple.

In my old programs, I had a problem with duplicate orders, in which customers forgot that they placed an order and do it twice. With MVC, it looks like an order can be placed twice if you hit the back button.

So I was thinking of implementing like a hash code or something, in which I can use data from the cart, and the shoppers identity to create a code that can be recreated and checked against.

I was looking for ideas on this, or feedback thoughts and what I should use to generate the code.

I copy the cart contents to a order table, but decided to leave the cart items until the order is fulfilled or canceled on the back end this time.

We have existing two MVC applications and an Angular JS application with individual user accounts using Forms authentication. I have been asked to implement a single sign on mechanism using ASP.Net Identity. I'm very much new these concepts. Kindly help me with this implementation. Thanks in advance.

Ask old accounts to upgrade their details using the new system. Otherwise use the details provided in database etc. to create their new accounts on new system; ASP.NET Identity.

Asking users will be simple, as you can ask them to re enter the password so that new password policies can be met. Secondly, maybe new system requires a two-way authentication, or email verification and you can do so when they create a new account themselves after trying to login to their accounts using old email.

Hi Afzaal,
Thanks for your reply.
Can you please guide me through the implementation. It's very urgent.
