Question

I have class connection
public partial class Connections
{
public System.Guid IdConnection { get; set; }
[Required(ErrorMessage = "Requienter code hereenter code here`red")]
public string Sign { get; set; }
[DataType(DataType.Date)]
[Required(ErrorMessage = "Required")]
public System.DateTime Date { get; set; }
[DataType(DataType.Time)]
[Required(ErrorMessage = "Required")]
public System.DateTime Time { get; set; }
[Required(ErrorMessage = "Required")]
public double Band { get; set; }
[Required(ErrorMessage = "Required")]
public string Modulation { get; set; }
[Required(ErrorMessage = "Required")]
public int RST { get; set; }
public string Comment { get; set; }
[Required(ErrorMessage = "Required")]
public string QLS { get; set; }
}
Method in controller:
[HttpPost]
public ActionResult DeleteMultiple(System.Guid[] deleteInputs)
{
var db= new MainDbContext();
var connections = db.Connections.ToList();
if (deleteInputs == null)
{
}
foreach (var item in deleteInputs)
{
Connections con = db.Connections.Find(item);
db.Connections.Remove(con);
}
db.SaveChanges();
return RedirectToAction("EditDelete", "Connection");
}
and View:
#model IEnumerable<RadioSite.Connections>
#{
ViewBag.Title = "My connections";
}
<table class="table">
<tr>
<th>
Select
</th>
<th>
#Html.DisplayNameFor(model => model.Sign)

#Html.DisplayNameFor(model => model.Date)

#Html.DisplayNameFor(model => model.Time)

#Html.DisplayNameFor(model => model.Band)

#Html.DisplayNameFor(model => model.Modulation)
</th>
<th>
#Html.DisplayNameFor(model => model.RST)
</th>

#Html.DisplayNameFor(model => model.Comment)

#Html.DisplayNameFor(model => model.QLS)

<th colspan="2">

</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
<input type="checkbox" name="deleteInputs" id="deleteInputs" value="#item.IdConnection" />
</td>
<td>
#Html.DisplayFor(modelItem => item.Sign)
</td>
<td>
#Html.ValueFor(modelItem => item.Date, "{0:dd/MM/yyyy}")
</td>
<td>
#Html.ValueFor(modelItem => item.Time, "{0:HH:MM}")
</td>
<td>
#Html.DisplayFor(modelItem => item.Band)
</td>
<td>
#Html.DisplayFor(modelItem => item.Modulation)
</td>
<td>
#Html.DisplayFor(modelItem => item.RST)
</td>
<td>
#Html.DisplayFor(modelItem => item.Comment)
</td>
<td>
#Html.DisplayFor(modelItem => item.QLS)
</td>
<td>
#using (Html.BeginForm("Edit", "Connection", FormMethod.Get))
{
<input type="submit" value="Edit" formaction="/Connection/Edit/#item.IdConnection" />
}
</td>
<td>
#using (Html.BeginForm("DeleteItem", "Connection", FormMethod.Post))
{
<input type="submit" value="Delete" formaction="/Connection/DeleteItem/#item.IdConnection" />
}
</td>
</tr>
}
</table>
#using (Html.BeginForm("DeleteMultiple", "Connection", FormMethod.Post))
{
<input type="submit" value="Delete Selected"/>
}
I selected items in grid (checked checkbox) and in method :public ActionResult DeleteMultiple(System.Guid[] deleteInputs) array deleteInputs always is null.

Your html.beginform pointing to "DeleteMultiple" has nothing being passed to it! You need to either restructure your view to include the inputs in your form or, since this is a delete function, make an ajax call to your controller action and send in the values of the selected check boxes.
