now i get returned the html code in the ajax call. i just need to know how i can render the table again with the new data because i really don't get how i can do that. I found some stuff on internet that says use $(MyPartialName).html(data) but that doesn't work for me so is there another way to do it or did i forget something(i did add the unobtrusive-ajax.js in the _Layout). Hope somebody can help me with this thank you very much in advance :D
Your jQuery selector is not valid. In your script tag change like following
$('#checkbox5yearsfilter').click(function () {
if ($('#checkbox5yearsfilter').is(':checked')) {
And replace this
<span>
#Html.Partial("_SearchSkills", ViewData.Model);
</span>
with this
<span id="_SearchSkills"></span>

I'm trying to display a button because I need to add new information but there is a list within the file and it is not working
I am using ASP.NET Core MVC and C#.
It is something like this:
HTML File:
#model IEnumerable<MyApplication.Models.Clients>
<table class="table" id="Tabla4">
<thead>
<tr>
<th>
#Html.DisplayNameFor(model => model.CODE)
</th>
<th>
#Html.DisplayNameFor(model => model.NAME)
</th>
<th></th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.CODE)
</td>
<td>
#Html.DisplayFor(modelItem => item.NAME)
</td>
<td>
</td>
</tr>
}
</tbody>
</table>
My controller method:
public ActionResult Create()
{
List<Clients> clients = dbContext.GetClients().ToList();
return View(clients);
}
I want to add this in my HTML file:
<div class="row">
<div class="col-md-4">
<form asp-action="Create">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="CODE" class="control-label"></label>
<input asp-for="CODE" class="form-control" />
<span asp-validation-for="CODE" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="NAME" class="control-label"></label>
<input asp-for="NAME" class="form-control" />
<span asp-validation-for="NAME" class="text-danger"></span>
</div>
<div class="form-group">
<input type="submit" value="Create" class="btn btn-primary" />
</div>
</form>
</div>
</div>
I tried to add this:
#Model MyApplication.Models.Clients
I get this error:
The model directive may only occur once per document
How can I solve it?
EDIT:
My Client Model is this:
public class Clients{
public int CODE {get; set;}
public string NAME {get; set;}
}
If i put the button inside the HTML File it throws and error:
#model IEnumerable<MyApplication.Models.Clients>

This is my Controller Create HTTP METHOD:
public ActionResult Create([Bind] Clients clients)
{
try
{
if (ModelState.IsValid)
{
dbContext.InsertData(clients);
return RedirectToAction("Index");
}
return View(clients);
}
catch
{
return View();
}
}
You cannot use asp-for="..." when the model/value you are using does not have these properties. Your model is defined as IEnumerable<MyApplication.Models.Clients> as the value for the view is a List<MyApplication.Models.Clients> object. When you use <input asp-for="CODE"> it looks for a property CODE inside the IEnumerable<...> type. However, this interface does not have such a property.
In your case you don't need asp-for="". Instead you can use a "normal" <input> tag with the name="..." attribute you want, depending on the Create() action you have defined. The code can look like this:
<div class="form-group">
<label for="CODE" class="control-label">Code:</label>
<input name="CODE" class="form-control" />
</div>
That way the HTTP Request will have the field name CODE in the POST body or GET URL parameter list, depending on how you send the form. ASP.NET will automatically fill the values into the parameters of your Create() action for you.
I create a view and create two cards to show new skill and current skill.
The problem is TittleNewSkillEHS back to the controller cero data after I select a new skill.
Short description of my request
I will need to display two lists with information about New Skill (required checkbox to select and add current skill), Current skill (required update target).
One approached to solution the request I create a view model take EmployeeTitle id, Title name, and two list
• List Current skills
• List New skills

TitleSkillVM TitleSkillVMNew = new TitleSkillVM();
TitleSkillVMNew.TitleId = SelectTitle.TitleId;
TitleSkillVMNew.TitleDescription = SelectTitle.TitleName;
TitleSkillVMNew.TittleNewSkillEHS = _tempNewEHS; “New skill”
TitleSkillVMNew.TittleSkillEHS = _tempEHS; “List Current skill”

I am having trouble with this last part of my project. I have all of my SQL Table columns filled up except for this last part. I have two tables WorkSchedule and WorkShiftBid.
In WorkShiftBid, I have WorkShiftBidID,WSBidDateTime,WSBidStatus,WorkScheduleID,StaffID
I will be using Guid.NewGuid() for WorkShiftBidID, Datetime.now for WSBidDatetime, A hardcoded "pending" value for WSBidStatus, A viewbag for StaffID and I am trying to get the WorkScheduleID to work but to no avail.
For WorkSchedule, I am trying to get just the "WorkScheduleID" attribute just by using a button method asp-route-id="#item.WorkScheduleID" and it will redirect me to the Create page whereby I will select a Staff from the drop-down list and then save it to my WorkShiftBid table as it has a foreign key for "WorkScheduleID".
It would be helpful if someone could help me. Thank you.
Controller Code:
public IActionResult CreateWorkShift()
{
ViewData["StaffID"] = new SelectList(_context.Staff, "StaffID", "StaffName");
return View();

return NotFound();
}
if (ModelState.IsValid)
{
workShiftBidModel.WSBidDateTime = DateTime.Now;
workShiftBidModel.WorkShiftBidID = Guid.NewGuid();
_context.Add(workShiftBidModel);
await _context.SaveChangesAsync();

Do you mean you cannot get the WorkScheduleID in public async Task<IActionResult> CreateWorkShift(Guid? id, [Bind("WorkShiftBidID,WSBidDateTime,WSBidStatus,WorkScheduleID,StaffID")] WorkShiftBidModel workShiftBidModel).If so,you need to get and pass Id in public IActionResult CreateWorkShift.Here is a demo worked:
public IActionResult CreateWorkShift(int id)
{
List<Staff> list = new List<Staff> { new Staff { StaffID = 1, StaffName = "staff1" }, new Staff { StaffID = 2, StaffName = "staff2" } };
ViewData["StaffID"] = new SelectList(list, "StaffID", "StaffName");
WorkShiftBidModel w = new WorkShiftBidModel { WorkScheduleID = id };
return View(w);

<input type="submit" name="bulkUpload" value="bulk upload" asp-route-data="#items"/>
</div>
</div>
</form>
public async Task OnPostAsync(List<Product> upload)
{
}
You need to render your products in such way that the Modelbinder will be able to pick them up on form submit and pass them into the codebehind.
Something like this (done by hand so it might not compile at first):
#{
for (int i = 0; i < Model.Products.Count; i++)
{
<input type="checkbox" asp-for="Model.Produtcs[i].Checked" />
#Model.Products[i].Number
#Model.Products[i].Name
}
}
This will render HTML like
<input type="checkbox" name="Products[0].Checked" />
<input type="checkbox" name="Products[1].Checked" />
<input type="checkbox" name="Products[2].Checked" />
And it should get back to your OnPostAsync. If not then try changing
public async Task OnPostAsync(List<Product> upload)
to
public async Task OnPostAsync(YourModel model)
What ever your full model is named.
This is then redundant:
#{
var items = Model.Products.Where(x => x.Checked);
}
I have a view with a form, when that form is submitted I want to show another view inside the first view. I have tried with partialview (not sure that is for my purpose?) but I cant get it to work because the model is null (its strongly-typed partialview). But I just want it to be created on the submitbutton and then it should be OK.
So, help my create a view/partialview inside a when submitting my form. Right now I get "Object reference not set to an instance of an object." on the foreach loop in my partial view, but it's not supposed to be created until the form is submitted.
My view:
<div class="calcInput">
#using (Html.BeginForm("ShowDetail", "Calculation"))
{
<div class="calculateBox">
<label for="calcOption">Choose value to calculate:</label>
<select form="anFormCalcInput" id="calcOption" title="Choose what value you want to calculate">
<option value="anPMT">Payment (PMT)</option>
<option value="anI">Interest (I)</option>
