I have a form where the model contains subcategories (a student model with many courses to add to the student model), these models should be selected from dynamically created cascading dropdown lists, do you have a tutorial for that?

Hi Aniz, Nice tutorial as always. I have a suggestion to make here. Can you use ES6 javascript to code as jquery is old. Also hard coding the JS function in the HTML element is also considered a bad practice. Add Event Listener instead.

countrydl.addEventListener("change", () => {
let countryID = countrydl.value;
LoadStates(countryID);
});

You can empty the Select List / DDL this way:
option').forEach(option => option.remove());


Modern way of coding things.

Thanks Aniz it helped me alot with my school project. I have a question, i created login and register throw new scaffolded item, identity but i cant figure out how to connect it to this same database?

I enjoy the video, but there is a link to the source code during the lesson. The issue is that the link is not working,
or have you moved it?
I have an error, so I have to see if it's a typo or something else,
Is it possible to get it?

Thanks

Hi Aniz, I am one of big fan and subscriber who's enjoying watching your videos and honestly get me tackle some real problems. I was looking for a way to contact you, I got question regarding one of the technique you taught us and I really need to understand it much deeper in order to complete one of my advanced training project. I checked you on every angle without success. Once I get notification that you uploaded another video I said thanks God maybe it could be a way to reach you. I will appreciate once you will ping me. Thanks in advance.

Hi Codes, Source code can't be download, 404 error.

Introducing FOREIGN KEY constraint on table 'Customers' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
