- Advanced AJAX CRUD in ASP.NET Core MVC and Dynamic Cascading Select list
In this ASP.NET Core Tutorial,
We will learn how to Create Cascading Select List.
and populate the selectlist dynamically using AJAX.
The first select dropdown list has Country Names.
and the second selectList has City Names. when we select a Country From the Country Selectlist the cities of the Selected Country will be loaded
in the cities selectlist from the Database using the AJAX Call.
I have Used AJAX and Partial views to create this Application.
AJAX (Asynchronous JavaScript and XML) in the Web Application is used to update parts of the existing page and to retrieve the data from the Server asynchronously.
AJAX improves the performance of the Web Application and makes the Application more interactive.
Bootstrap is one of the most popular HTML, CSS and JS frameworks for developing responsive, mobile first projects on the Web.
In this Application you will learn how to do Partial refresh of the Listing Screen and avoid the loading of Lists after the CRUD operations from the database.
Please watch the full video and put your valuable suggestions in the comment box.
Thank You.

Thank you and greetings from Bulgaria.
Following your code closely and your tutorial, not very closely, I noticed that you do not have List or IEnumerable in the City model for students. One City can have many students.
Same for goes the Country. One Country can have many cities.
Since I am somewhat midd level but with many gaps, please help. Why was that ??
Thank you.
Very Good video. I could not find the text file in which the codes are written. Could you please give a link?
Greate veido , thanks
You are Welcome

Let's we have 200 countries in the list , is it possible to search the country by name or code instead of scrolling a long list ?
Sir this project is very good and helpful for my training session...so thank you sir...
Please sir send the zip file this project
Given zip file is not found
Please sir share your source code...
Hi! I'm having two problems with this tutorial that I can't figure out. First, when I try to edit a customer record, as soon as I click the 'Edit' button, the text box for the filename is highlighted in blue and nothing happens. I think this is some kind of client side problem because I put a breakpoint in the HttpPost Edit action and it was never hit. There is an image associated with the record and it appears in the Profile Photo box. My second problem is that I can't delete a customer record. I get an error, "Cannot insert the value null into column 'Code', table 'Household.dbo.Countries'; column does not allow nulls. INSERT fails..... (I used an existing 'Household' database.
Update - Started over from scratch and edit now working but still having same problem deleting a customer. I've spent hours searching for solution. Any help would be appreciated. An actual delete was not demonstrated in the tutorial so not sure code is correct.
_context.Attach(customer);
_context.Entry(customer).State = EntityState.Deleted;
_context.Entry(customer.City).State = EntityState.Detached;
_context.Entry(customer.City.Country).State = EntityState.Detached;
_context.SaveChanges();
return RedirectToAction(nameof(Index));
@@CodeSbyAniz guys if this code of the instructor didn't work try this it will work
_context.Attach(customer);
_context.Entry(customer).State = EntityState.Deleted;
_context.Entry(customer.City.Country).State = EntityState.Detached;
_context.SaveChanges();
return RedirectToAction(nameof(Index));
this worked will and the row deleted successfuly

Hello, I tried your Video because im a newbie, but since the Modal I have not understand the Steps because there is someting Wrong..in Video you call function as Coutries not as Countries, then you put one function called cityCreateModal into side.js under a function ShowCountryCreateModal, where I not have seen, that it was Copied. In the Video sinc 1:21:12 beginning there is something wrong because I have tried to do the same as you, but i can not insert a Customer (Country) like your video...can you help me please?
Sir from where we can see the inward and outward videos of transaction
Bro thank u so much but Column Country is empty. How can i fill the column country after select country in create or edit?
You are most welcome, Please watch again, complete source is given with the video. follow the steps shown. you can make it.
Hi there just wondering about the token that is on the post controller methods to prevent a cross script attack. Do you think it is important security wise, is this necessary and is there a simple way to get this to work when uising the MCV razor AJAX helper methods. I see some posts on the internet where the token can be included in a seperate jquery script at the end of the cshtml file. In summary is the token necessary and what is the best way/most straightforaward way to include it into partial razor views where the AJAX mvc helpers are used. I want to stay away from separate script sections in views where possible, defeats the purpose of the Razor Ajax helpers and also no doubt there will be conflicts I am sure between the ajax mvc helpers and a seperate script section in the same AJAX post from the view
Thanks for the Idea. will do a tutorial on it in the future.
