In my index page I have A html.ActionLink like this:
<table>
<tr>
<td>
#Html.DisplayFor(modelItem => item.TestInstanceID)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id=item.TestInstanceID }) |
#Html.ActionLink("Details", "Details", new { id=item.TestInstanceID }) |
#Html.ActionLink("Delete", "Delete", new { id=item.TestInstanceID })|
#Html.ActionLink("Select", "Create","StudentTestMark", new {id = item.TestInstanceID}, null)
</td>
</tr>
}
</table>
which will pass the TestInstanceID to StudentTestMark Controller Create Action.
but when I Run it. id is Null.
public ActionResult Create(int? id)
{
// Get TestInstance
var testInstance = tt.GetByID(id);
........
}
An exception of type 'System.NullReferenceException' occurred in SHub.dll but was not handled in user code
Can't figure out what is wrong here, Please help.

I have images in wwwroot/photos dir and I want to display the images in a table after adding a new item (animal), along other details from my database.
Here is the Index page, showing my data without images displaying-
All my images are in wwwroot/photos dir.
I've tried to print the value of PhotoUrl on Index View and saw that it get this path -
wwwroot\Photos\Cats\Leon.jpeg
So what is the right way show my images ?
here are the relevent parts of my code:
Storage Service-
public class StorageService : IStorageService
{
readonly IHostingEnvironment _hostingEnvironment;
public StorageService(IHostingEnvironment hostingEnvironment)
{
_hostingEnvironment = hostingEnvironment;
}
public string AbsolutePath => _hostingEnvironment.WebRootPath;
}
Image Service-
public class ImageService : IImageService
{
readonly IStorageService _storageService;
public ImageService(IStorageService storageService)
{
_storageService = storageService;
}
//puts Image folder on wwwroot
public string ImageDir => Path.Combine(_storageService.AbsolutePath, "Photos");
//puts the category name under Image folder
public string CategoryDir(string name) => Path.Combine(ImageDir, name);
public string GetFullImageUrl(Animal animal, IFormFile imageFile)
{
var fileName = $"{imageFile.FileName}";
return Path.Combine(CategoryDir(animal.Category.Name), fileName ?? "");
}
public Task EnsureDirCreated(Category category)
{
Directory.CreateDirectory(CategoryDir(category.Name));
return Task.CompletedTask;
}
public async Task<(bool,string)> UploadImage(IFormFile imageFile, Animal animal)
{
if (imageFile != null && imageFile.Length > 0)
{
var fileName = $"{imageFile.FileName}";
//create file path
var categoryPath = CategoryDir(animal.Category.Name);
await EnsureDirCreated(animal.Category);
string fullPath = Path.Combine(categoryPath, fileName);
using (var fileStream = new FileStream(fullPath, FileMode.Create))
{
await imageFile.CopyToAsync(fileStream);
}
return (true,fullPath);
}
return (false,String.Empty);
}
}
Animal Service-
public async Task<Animal> AddAnimalAsync(Animal animal, IFormFile image)
{
animal.Category = await _categoryService.GetAsync(animal.CategoryId);
var (isSuccess, imageName) = await _imageService.UploadImage(image, animal);
if (isSuccess)
{
animal.PhotoUrl= imageName;
_animalRepository.Add(animal);
return animal;
}
return null;
}
CreaeAnimal ViewModel-
public class CreateAnimalViewModel
{
public Animal Animal { get; set; }
public IFormFile Photo { get; set; }
}
Controllers-
public async Task<IActionResult> Index()
{
var petShopData = _animalService.GetAnimalWithCategoryAsync();
return View(await petShopData);
}
public async Task<IActionResult> CreateAnimal()
{
var categories = await _categoryService.GetAnimalCategory();
ViewBag.Categories = categories.Select(c => new SelectListItem(c.Name, c.CategoryId.ToString())).ToList();
return View();
}
[HttpPost]
public async Task<IActionResult> CreateAnimal([FromForm] CreateAnimalViewModel vm)
{
await _animalService.AddAnimalAsync(vm.Animal, vm.Photo);
return RedirectToAction("Index");
}
Index View-
#model IEnumerable<PetShop.Data.Models.Animal>
#{
ViewBag.Title = "Index";
}
<h1>Index</h1>
<p>
<a asp-action="CreateAnimal">Create New</a>
</p>

add the codes in your startup class:
app.UseStaticFiles();
if you added the codes,you could try to view your pic and check if it exist as below:
i have the following page generated
when i click the Edit link, the record data must be sent to the input boxes on teh same page (without refreshing the page)
currently i have the controller code and views

How do i modify my code to send data those input control and in my code how do i create hidden field for Id value so it can be send to the Edit(collection, int id) action to update the record?
for Stephen Muecke, i have added my jquery files through the bundles
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/ecomm").Include(

}
In the partial view
#Ajax.ActionLink("Edit", "Edit", "ProductCategory", new { id = item.Id }, new AjaxOptions { HttpMethod = "GET", OnSuccess = "loadformdata" }) |
#Ajax.ActionLink("Delete", "Delete", "ProductCategory", new { id=item.Id}, new AjaxOptions{ HttpMethod="POST", OnSuccess="loadformdata"})
in the index view the following js function:
function loadformdata() {
var cells = $(this).closest('tr').children('td');
alert(cells.eq(0).text());
//$('#Code').val(cells.eq(0).text());
//$('#ProdName').val(cells.eq(1).text());
}
To: Stephen Muecke:
i have removed above loadformdata() and put everything as you said. this youtube video shows the problem that still does not call that click event
To: Steven Meucke:
there's still no luck, for ease i have added a alert() in the function and the alert() won't show. Here is the video
Give you 'Edit' link a class name (say) class="edit" and handle its .click() event to update the form controls
$('.edit').click(function() {
var cells = $(this).closest('tr').children('td');
$('#Code').val(cells.eq(0).text());
$('#ProdName').val(cells.eq(1).text());
return false; // cancel the default redirect
});
Side note: You could just replace the ActionLink() code with Edit and the return false; line is not necessary.
write script for ajax call:
$('#edit').click(function () {
// var data = {here you will pass item.id }
$.ajax({
url:'ProductCategoryController/Edit',
data: {id : data}
method:'GET',
success: function (data) {
//clear html page here
//reload html page by passing 'data' passes in function
//e.g. suppose html page id is 'xyz' then $("#xyz").html(data)
}
});
});
Im trying to populate data in a view from an sql db. Im selecting all recipes from a specific counry...O.k...I also want to display the country name at the top of the view but im having problems returning the result to the view. Any ideas would be greatly appreciated...
Heres my code
#model IEnumerable<FoodB.recipeTbl>
<h2>************where i want to put the country title***************88</h2>
<table>
<tr>
<th>
#Html.DisplayNameFor(model => model.recipe_title)
</th>
<th>
#Html.DisplayNameFor(model => model.ingredients)
</th>
<th>
#Html.DisplayNameFor(model => model.country_id)
</th>
<th></th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.recipe_title)
</td>
<td>
#Html.DisplayFor(modelItem => item.ingredients)
</td>
<td>
#Html.DisplayFor(modelItem => item.country_id)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id=item.id }) |
#Html.ActionLink("Details", "Details", new { id=item.id }) |
#Html.ActionLink("Delete", "Delete", new { id=item.id })
</td>
</tr>
}
</table>
Here's my controller
public ActionResult Index(int id)
{
//select all recipes for country
var query = db.recipeTbls.Where(c => c.country_id == id);
//get country from country table*******how to return this***********
var ctry = db.countryTbls.Where(country => country.id == id);
return View(query);
}
Use SingleOrDefault instead of Where since you are looking for one entry only
public ActionResult Index(int id)
{
//select all recipes for country
var query = db.recipeTbls.SingleOrDefault(c => c.country_id == id);
//get country from country table*******how to return this***********
var ctry = db.countryTbls.SingleOrDefault(c => c.id == id);
ViewBag.Country = ctry;
return View(query);
}
View
<h1>ViewBag.Country </h1>
viewbag is a field that is dynamic. you can set it to whatever type you want. So on your controller
ViewBag.Country = ctry;
then in your view
<label>#ViewBag.Country</label>
You can use the ViewBag.
The controller
public ActionResult Index(int id)
{
//select all recipes for country
var query = db.recipeTbls.Where(c => c.country_id == id);
//get country from country table*******how to return this***********
var ctry = db.countryTbls.Where(country => country.id == id);
ViewBag.country = ctry.ToString();
return View(query);
}
The view
#model IEnumerable<FoodB.recipeTbl>
<h2>ViewBag.country</h2>
Hope it worked.
I am using MVC and razor.
I have sucessfully implemented a way for the user to dynamically add more input rows at a click of a button (using AJAX and following Steven Sanderson's blog). BUT I do not know how to save the data to a database that the user inputs in these dynamically created fields.
I use his helper class, that quite frankly I am struggling to understand at all.
My question is what do I need to put in the POST create method. The link to the code in his blog is here:
steven sanderson's blog
Just a pointer in the right direction is all I need. THis is my current code:
New row partial view:
#model ef_tut.ViewModels.ClaimsViewModel
#using ef_tut.WebUI.Helpers
#using (Html.BeginCollectionItem("claims"))
{
<table class="editorRow">
<tr >
<td>
SubmissionUserID: #Html. EditorFor (o.claim.SubmissionUserID)
</td>
<td>
ClaimID: #Html.EditorFor(o => o.claim.ClaimID)
</td>
<td>
#Html.EditorFor(o => o.claim.ApprovedYN)
</td>
<td>
ClaimID(claimlinetable)#Html.EditorFor(o => o.claimline.ClaimID)
</td>
<td>
ClaimantUserID: #Html.EditorFor(o => o.claimline.ClaimantUserID)
</td>
<td>
Hours: #Html.EditorFor(o => o.claimline.Hours)
</td>
<td>
MileageCost: #Html.EditorFor(o => o.claimline.MileageCost)
</td>
<td>
TravelCost: #Html.EditorFor(o => o.claimline.TravelCost)
</td>
<td>
Hours cost: #Html.EditorFor(o => o.claimline.HoursCost)
</td>
<td>
Total cost: #Html.EditorFor(o => o.claimline.TotalCost)
</td>
<td>
ProxyYN: #Html.EditorFor(o => o.claimline.ProxyClaim)
</td>
<td>
CatID: #Html.EditorFor(o => o.claimline.CatID)
</td>
<td>
SubCatID: #Html.EditorFor(o => o.claimline.SubCatID)
</td>
<td>
delete
</td>
</tr></table>
}
Blankeditorrowmethod
public PartialViewResult BlankEditorRow()
{
return PartialView("NewRow", new ClaimsViewModel());
}
My current POST method that creates new DB records but all fields are null
[HttpPost]
public ActionResult Create(ClaimsViewModel viewModel)
{
if (ModelState.IsValid)
{
db.claims.Add(viewModel.claim);
db.claimlines.Add(viewModel.claimline);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(viewModel);
}
Create view
#model ef_tut.ViewModels.ClaimsViewModel
#{

}
<h2>Create</h2>
#using (Html.BeginForm()) {
#Html.ValidationSummary(true)
<fieldset>
<legend>claim</legend>
<div id="editorRows"></div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}

success: function (html) { $("#editorRows").append(html); }
});
return false;
});

return false;
});

templateInfo.HtmlFieldPrefix = htmlFieldPrefix;
}
public void Dispose()
{
templateInfo.HtmlFieldPrefix = previousHtmlFieldPrefix;
}
}
}
}
Use FormCollection, so instead of this:
[HttpPost]
public ActionResult Create(ClaimsViewModel viewModel)
{
}
You will have this:
[HttpPost]
public ActionResult Create(FormCollection formCollection)
{
}
You should be able to get the value for any new fields you have created using their name like so:
var newFieldValue = formCollection["newFieldName"];

1 Question - this is proper way which i have done ?
2 Question - how to return custom value from Paypal
3 and also see the web.config file after the payment should i called the PIN ?
Please guide me ...... and how to do payment process
I was looking for information on this recently as well. There is sample code on the paypal site, but I find it quite terse and it is hard to put it into context in your application. The best that I could find is the video and sample by Rob Conery.
First, look at the video. It is called "ASP.NET MVC Storefront Part 1: Architectural Discussion and Overview". Currently it can be found here. Skip ahead to 15:21 to get to the paypal part.
Then download the source code. You are looking for 'ASP.NET MVC Storefront sample code which can currently be found here.
Once you have extracted the code, search for IPN() for IPN method and PDT() for PDT method.
