我有课程连接
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; }
}
控制器中的方法:
[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");
}
和查看:
@model IEnumerable<RadioSite.Connections>
@{
ViewBag.Title = "My connections";
}
<table class="table">
<tr>
<th>
Select
</th>
<th>
@Html.DisplayNameFor(model => model.Sign)
</th>
<th>
@Html.DisplayNameFor(model => model.Date)
</th>
<th>
@Html.DisplayNameFor(model => model.Time)
</th>
<th>
@Html.DisplayNameFor(model => model.Band)
</th>
<th>
@Html.DisplayNameFor(model => model.Modulation)
</th>
<th>
@Html.DisplayNameFor(model => model.RST)
</th>
<th>
@Html.DisplayNameFor(model => model.Comment)
</th>
<th>
@Html.DisplayNameFor(model => model.QLS)
</th>
<th colspan="2">

</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>

@Html.ValueFor(modelItem => item.Time, "{0:HH:MM}")

<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"/>
}
我选择了网格中的项目(选中复选框),方法:public ActionResult DeleteMultiple(System.Guid[] deleteInputs)
数组deleteInputs
中的项目始终为空。
答案 0 :(得分:0)
你的html.beginform指向&#34; DeleteMultiple&#34;没有任何东西传递给它!您需要重新构建视图以在表单中包含输入,或者由于这是一个删除功能,因此对控制器操作进行ajax调用并发送所选复选框的值。
