@CodeS I am confused, there are 7 videos in this playlist. are video 1 and 2 related and there rest of 5 videos are independent for additional learning?
Great Job, It Is Very Helpful bro and I am new to this channel.
Welcome on board! Thank You.
I'am working on VS code as my OS is Ubuntu can you provide me the whole project as iam unable to create the View automatically for provided action methods through scaffolding.
I had this SQL exception "Invalid column name 'PhotoUrl'.' " I do not think it was stored in the database, when I did the migration I got a warning that there was already an object named applicants. I find your tutorials exceptionally good as I really struggle with things but, you explain things very well. I could re-do the whole solution but I would like to understand what it is I did wrong. Many Thanks!!
simple, drop the database and delete all migrations. then do the Add-Migration. that will solve the issue.
Please teach this with Api method
In the function to AddItem(btn) the 'btn' variable stays grey and when I mouse over the variable it says " 'btn' Is declared but value is never read". Help please as your lessons are very good!! Thank You so much!
Excellent demonstration Mr.Aniz. Keep it up. If possible provide the same video for razor pages environment
Thank You, Sure I will.
Really, thank you very much.
You are Most welcome!
I could not get the buttons to change as the btn prop was null.. I copied the code from you article so it was the same code. Not sure why the javascript did not show and hide the buttons as needed...
Excellent work dear friend
Thank you! Cheers!
Awesome
Thank You !! . Very informative :)
Glad it was helpful! You are welcome.

On my visual studio the table.insertRow() does not exist. Any suggestions to make it work?
table.insertRow() is JavaScript function, you don't need to worry if visual studio shows error. just compile and run . it should work.
@@CodeSbyAniz my console browser simply says it's not defined
Great video thanks! I have an error in the browser js console that says "Uncaught TypeError: delbtn is null", when I click the add button to add a row. The row is added, but the delete button does not become visible. I noticed in the inspector that the delete and add button units are zero, for example "
I figured it out, I missed a comma in the last rowOuterHtml line, goodness gracious.
Cicha Delete hone k bad nahi work horaha🤔
any suggestion
Thank you very much, the video is very helpful and informative. Where can I find the video for the edit button?

Thank you for such a wonderful learning video. The AddRow() is not working at my end. When checked using the alert() command I could see the rows are being added but they are not being displayed on the screen. Any help would be appreciated.
function AddItem(btn){
var table= document.getElementById('ExpTable');
var rows = table.getElementsByTagName('tr');
alert(rows);
var rowOuterHtml = rows[rows.length - 1].outerHTML;
alert(rowOuterHtml);
alert(table.rows.length);
var newRow= table.insertRow();
newRow.innerHtml = rowOuterHtml;
alert(table.rows.length);
}
Thanks for watching. please find below complete function code.
function AddItem() {
var table = document.getElementById('ExpTable');
var rows = table.getElementsByTagName('tr');
var lastrowIdx = rows.length - 1;
var rowOuterHtml = rows[lastrowIdx].outerHTML;
lastrowIdx = lastrowIdx - 1;
var nextrowIdx = eval(lastrowIdx) + 1;
rowOuterHtml = rowOuterHtml.replaceAll('_' + lastrowIdx + '_', '_' + nextrowIdx + '_');
rowOuterHtml = rowOuterHtml.replaceAll('[' + lastrowIdx + ']', '[' + nextrowIdx + ']');
rowOuterHtml = rowOuterHtml.replaceAll('-' + lastrowIdx, '-' + nextrowIdx);
var newRow = table.insertRow();
newRow.innerHTML = rowOuterHtml;
rebindvalidators();

I AM GETTING ISSUE IN STARTUP CLASS
TUTORIAL IS DONE IN 2019 VERSION I AM WORKING IN 2022 VERSION SO STARTUP CLASS IS REMOVEDIN THIS VERSION TIME IN VIDEO 8:48 I THINK I AM MISSING THIS STEP THATS WHY I CAN CREAT INDEX VIEW AUTOMATICALLY PLZ LETME KNOW HOW CAN I FIX IT
This will work for any version. Because most of the logics are done using JavaScript. nothing to do with the startup.cs
In new version 2022 insted of "Startup.cs" open "Program.sc" file from root of your project.
Insert ths code at the top of the file:
using Microsoft.EntityFrameworkCore;
using ResumeManagerManager.Data;
//And after this line in Program.cs
//builder.Services.AddControllersWithViews();
//insert this
builder.Services.AddDbContext(options => options.UseSqlServer(builder.Configuration.GetConnectionString("DbConn")));
Thanks for Nice Tutorials , can please sent us some Code ?? becz. getting some error i completed 90% work but get error , can you please help me
you are most welcome
Thanks for your contribution. Could you please share the source code
You are Most Welcome, The complete source is shown in the video. Please note it by pausing the video.
Hi, I have gone through your video more than twice but couldn't find any mention about the custom-input-file that you have used in the AddItem function. Will the Add button function yield any result without this js file? If not than provide the contents of the js file.
Hi, Thanks for watching, Custom-input-file is a class name for image file uploading control. it has nothing to do in the Additem method. Please watch again. definitely you will understand.
