I have a form in my View with a table and on each cell i have a checkbox. I already have individual Ids for every single checkbox but I dont know how to pass them individually to controller action. I know how to pass single parameters over the "name" attribute but Im not sure on how to handle it with so many diffrent checkboxes.
View
@{
bool IsOwnRegistration = false;
foreach (var item in Model.Events.Where(i => i.UserId == Model.UserID && Convert.ToDateTime(i.Date) > dateTime))
{
if (item.HasCreatedOtherUsers == null)
{
IsOwnRegistration = true;
}
string Surname = "";
string Lastname = "";
<tr>
@{
foreach (var Useritem in Model.Users.Where(i => i.UserId == item.HasCreatedOtherUsers))
{
Surname = Useritem.Vorname;
Lastname = Useritem.Nachname;
}
if (IsOwnRegistration == true)
{
<th style="background-color:grey; width:33%;">
Meine Reservation
</th>
<th style="width:33%;">@item.Date</th>
<th style="width:33%;">
<div class="custom-control custom-checkbox ">
<input type="checkbox" class="custom-control-input" name="@item.EventId" id="@[email protected]">
<label class="custom-control-label" for="@[email protected]"><i style="color:red;" class="fas fa-trash-alt"></i>
</label>
</div>
</th>
}
else
{
<th style="width:33%;">@Surname @Lastname</th>
<th style="width:33%;">@item.Date</th>
<th style="width:33%;">
<div class="custom-control custom-checkbox ">
<input type="checkbox" class="custom-control-input" name="@item.EventId" id="@[email protected]">
<label class="custom-control-label" for="@[email protected]"><i style="color:red;" class="fas fa-trash-alt"></i>
</label>
</div>
</th>
}
}
Controller
public ActionResult DeleteRegistrations(Need to get values of all checkboxes)
{
return RedirectToAction("HomePage");
}
In order to transmit the selected checkboxes to the action method, the checkboxes should share a common name that matches the parameter name of the action method. The following sample shows a Razor view that lists some strings in a table, creating a checkbox for each string:
@model IEnumerable<string>
@{
ViewBag.Title = "Home Page";
}
<div class="row">
<div class="col-md-12">
@using (Html.BeginForm("Index", "Home", FormMethod.Post))
{
<table>
@foreach (var s in Model)
{
<tr>
<td>
<input type="checkbox" name="selectedValues" value="@s" id="@s" />
<label for="@s">@s</label>
</td>
</tr>
}
</table>
<input type="submit" />
}
</div>
</div>
Please note that the name attribute of the checkboxes is set to "selectedValues", the value attribute is set to the original string (or an id in a more complex scenario).
The form is submitted by a POST request to the following action method:
[HttpPost]
public ActionResult Index(IEnumerable<string> selectedValues)
{
return View(selectedValues);
}
In the POST request, all the values of all checked checkboxes are transmitted as key value pairs in the form "name=value". As all of the checkboxes share the same name, ASP.NET MVC can deserialize this into an IEnumerable<string>.
