Hi Rahul,

Don't copy paste the code on the page. Attached the solution.. While repling there is option to upload the source code.

Add your code into .zip and upload the code.

Hello Arvind

now current error is : object referance not set to an object

HomeController.cs

public ActionResult Index(student stud)

return View(v);
}
public ActionResult BlogCreate()

}
[HttpPost]
public ActionResult BlogCreate(blog blg)
{
var blogcreate = dbstud.blog.Add(blg);
ViewData["blogdatas"] = blg;
dbstud.SaveChanges();
return View();
}

BlogCreate.cshtml

@model DemoFFI.Models.blog

Hi Rahul,

If possible, Please attached the source code. I will check and revert back you instead of unkown solutions.

Thanks

hello Arvind

[HttpPost]
public ActionResult BlogCreate(blog blg)
{
var blogcreate = dbstud.blog.Add(blg);
ViewData["blogdatas"] = blg;
dbstud.SaveChanges();
return View();
}

still give the null and error object referance not set to an object?

Hi Rahul,

You have added the wrong code. Add this one with return View();

[HttpPost]
public ActionResult BlogCreate(blog blg)
{
var blogcreate = dbstud.blog.Add(blg);
ViewData["blogdatas"] = blg;
dbstud.SaveChanges();
return View();
}

Hello Arvind

I think main issue is this line

IEnumerable bloggs = ViewData["blogdatas"] as IEnumerable;

bloggs this store the null?

Hello Arvind

as per your suggestion I add this

[HttpPost]
public ActionResult BlogCreate(blog blg)
{
var blogcreate = dbstud.blog.Add(blg);
ViewData["blogdatas"] = blg;
dbstud.SaveChanges();
return View(blogcreate);
}

still not work

give an error object reference not set to an object?

Hi Rahul,

I haven't tried but you can try and replace below code with

HttpPost]
public ActionResult BlogCreate(blog blg)
{
var blogcreate = dbstud.blog.Add(blg);
ViewData["blogdatas"] = blg;
dbstud.SaveChanges();
return View(blogcreate);
}

this one.

HttpPost]
public ActionResult BlogCreate(blog blg)
{
var blogcreate = dbstud.blog.Add(blg);
ViewData["blogdatas"] = blg;
dbstud.SaveChanges();
return View();
}

Hello Arvind not work after add this line

not work see this image?

issue is why giving the null? that is give the error object referance not set to an object

Hi rahul,

Try adding this header in BlogCreate.cshtml

@using System.Web.Mvc.Html;

Hello Arvind kushwah and salman beg

main issue is this line this line gives the null that is the reason object referance not set to an object

//issue is here bloggs gives the null that is the reason object referance not set to an object?

IEnumerable bloggs = ViewData["blogdatas"] as IEnumerable;

how to solve this issue?

Hi Rahul,

To handle and avoid above error please check the collection count. Iterate collection only when they have any items.

if(bloggs.Count> 1) {
foreach (blog blg in bloggs)
{
@blg.blogdescription
@blg.blogtype
}
}

Hey I think bloggs is null and due to that reason it is showing object reference not set to an instance of an object. First check whether it is null or not and then check why it is getting null. Thanks.

Hey You used ViewData["blogdatas"] = getblogdata(); to bind your blog data. But if you goto this method getblogdata(), in this method you created a list but in that list there is no data exists. First add some data into that list then you will see it will bind the data. Always debug the code and you will get more clarity that why it is not binding the data etc. Thanks.
