Part 28 Customizing the autogenerated edit view

[@azizyokubjonov7322]

I believe at 9:06 just removing [Bind] would be much better. Because in this scenario, we don't even use Name while saving changes. If we did that, we wouldn't be removing the [Required] attribute and editing the Create action.

Hi Harika, we will discuss this in our upcoming videos on validation.

[@naibedyakar]

You are Just Amazing how I Ask my self A question And see you answering right away in the video Great Work

[@avinashmamidi]

Hello SIr, In this video you had removed the required attribute on Name but if we do that on real time it is accepting null value for Name while creating a new Employee . Could you please advise on this ?

[@AdvikaSamantaray]

He mentioned adding the validation adding dynamically.

[@liedebunker1253]

Hey, I admire you for having made so many videos. I went to your main page on KZbin, and I saw countess video clips. Wow!

[@ammmaj]

Dear Sir It would be great if you could dive in details in the coming tutorials into building and customising dynamic data web sites. it is a very powerful method of accessing and displaying databases easily, and it would really make things easier for me to understand thanks to your great way of explaining things. Best of regards

[@AbbasBengali]

Sir, You used Hidden field previously, then why didn't it help make do with the required field issue? Why did you have to remove the required field attribute?

[@sudhanshu1709]

Required attribute from public class EmployeeMetaData has been revoked for edit operation, so how it will remain Mandatory for Create operation?

[@OrcaRiderTV]

How about having multiple Employee interfaces which dictate different requirements ? Employee : IEmployeeEdit, IEmployeeAdd wherease Name is required in IEmployeeAdd and not present in IEmployeeEdit Edit action will accept IEmployeeEdit and Create action will accept IEmployeeAdd

[@nostalgian4113]

asyncing controllers fixes this problem, i had no need to use bind model, fiddler couldn't interfere because of this line in the controller in the if condition await db.SaveChangesAsync(); and I didn't have to delete the [required] attribute too.

[@olliebutler3168]

How does that prevent unwanted changes?

[@ramilhuseynov2891]

if you remove [Bind(Exclude="Name")], you don't need to remove [Required] and it works the same as employee receives name, but you use previous name to save

[@Csharp-video-tutorialsBlogspot]

Hi Ramil - Please watch the next video and in that we discussed how to fix this issue. Hope this helps. Here is the link to the playlist. kzbin.info/aero/PL6n9fhu94yhVm6S8I2xd6nYz2ZORd7X2v

[@rishikmani]

How all the department names got loaded in the Edit page dropdown?

[@rdg515]

Could someone explain why it is not possible to simply assign employee.Name with the value from employeeFromDB.Name, and keep the employee object in the ChangeObjectState method? I tried it and it doesn't work, but I'm curious as to why.

[@nanda3281]

hellow sir , it does not work with ObjectStateManager in visual studio 2012 so how can we solve this problem.

[@dayanandthombare123]

Hello Sir, It's OK to retrieve the data from db when we want to edit because we are showing that particular data while editing.but what is need of retrieving the data from DB on the POST request of edit..?

[@harikaaakutota7776]

hi venkat, font color of error message is still in black color.how to change it and how to preceed * before error message.thanks in advance

[@ranyil]

After watching this video I am still asking myself why you do not add checking Gender field's value on submit here? For example: if (!new string []{"Male", "Female"}.Contains(employee.Gender)) { ModelState.AddModelError("Gender", "The Gender field is required"); }

[@ranyil]

Just forgot to add to use this needs using System.Linq.

[@islvatansever3394]

Some people may not want to specify their gender. That's the only reason.

[@codingtech2737]

you can also get rid of html.validatefor in the view fro name property, and it will work fine, but if you will get rid of required attribute, it will cause null names inserted when you use create new view............

[@naveenchawla70]

After Changing In Edit Controller when i m going run it i face a issue "Sequence contains more than one element " so now how can i resolve this issue ? sir please

[@tutorialfair1985]

How to handle Remote Attributes on when i edit or update

[@sachin5j]

how gender DD is retaining the value in Edit page?

[@user-wc3tz3be1j]

We got one more problem. let's say every employee is able to edit their info if they're logged in. then a malicious employee could pass some other employee's id through fiddler, .. booom!. Just changed someone's info . it happens of course without bind attribute. How we could handle this ? Venkat

[@munkhn73]

why not just add readonly attribute to html helper for name? like . if you remove [required] from model then you can send create(post) request with name=null which can be verified on client side.

[@munkhn73]

Munkh-Erdene Nasan what you are doing with the name is basically like 'ok A is 1. then second later. my whole life was a lie. the A was 0.'

[@munkhn73]

Munkh-Erdene Nasan ok. my bad for commented without watching the whole video. but still all of that problems could be fixed just by adding readonly attribute...

[@bilalyousuf6814]

we can still edit EmployeeId using fiddler which gives error.....

[@codingtech2737]

after getting rid of html.validate helper, simply assign name property from database object to incoming employee object, and you don,t have to change anything else.

[@plflores33011]

can you please upload a tutorial in inserting an image to the database and displaying it to a table using entity framework?..

[@nys8260]

instead, we can use ModelState.Remove("Name") in edit action

[@vatansoni6439]

Please clear my doubt sir, Why can not we use below approach for Edit, It gives error System.Data.OptimisticConcurrencyException was unhandled by user code {"Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries."} Code: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Edit([Bind (Exclude="Name")]Employee employee) { Employee employee1 = new Employee(); employee1.Name = db.Employees.Single(x => x.employeeID == employee.employeeID).Name ; if (ModelState.IsValid) { db.Employees.Attach(employee1); db.ObjectStateManager.ChangeObjectState(employee1, System.Data.EntityState.Modified); db.SaveChanges(); return RedirectToAction("Index"); } ViewBag.DepartmentID = new SelectList(db.Departments, "ID", "Name", employee1.DepartmentID); return View(employee1); }

[@user-wc3tz3be1j]

Hi, if we remove the required attribute, the client side validation will be gone too. Guess we have no choice to achieve this except writing a client side validation for this Name field.

[@arun9385]

You need to make a video on Register form which contain several Casacding ddl and on login form
