剑道内联编辑与IEnumerable模型属性
本文关键字：IEnumerable 模型 属性 编辑 | 更新日期: 2023-09-27 18:19:21
如果有人能提供以下建议，我将不胜感激:
我有一个模型包含另一个模型的集合:
public class ContractModel
{
public ContractModel()
{
this.ContractCurrencyClauses = new HashSet<ContractCurrencyClause>();
}
public System.Guid ID { get; set; }
public virtual ICollection<ContractCurrencyClause> ContractCurrencyClauses { get; set; }
//other model properties
}
public partial class ContractCurrencyClause
{
public System.Guid ID {get; set;} //PK
public System.Guid CONTRACT_ID { get; set; } //FK on ContractModel(ID)
public string CURRENCY { get; set; }
public Nullable<decimal> RATE { get; set; }
}
问题是，我不确定如何临时存储ContractCurrencyClauses的集合时，ContractModel正在创建。我将ContractModel的新实例传递给我的视图:
[HttpGet]
public ActionResult Create()
{
ContractModel Contract = context.Contracts.Create();
Contract.ID = Guid.NewGuid();
return PartialView(Contract);
}
在我看来:
@model ContractModel
@using (Ajax.BeginForm("Create", null, new AjaxOptions() { ... }))
{
@Html.HiddenFor(model=>model.ID)
@(Html.Kendo().Grid(Model.ContractCurrencyClauses)
.Name("ContractCurrencyClauses")
.ToolBar(toolbar => toolbar.Create())
.Columns(columns => {
columns.Bound(u => u.ID).Hidden(true);
columns.Bound(u => u.CONTRACT_ID).Hidden(true);
columns.Bound(u => u.CURRENCY);
columns.Bound(u => u.RATE);
columns.Command(command => { command.Edit(); command.Destroy(); });
})
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource =>
dataSource.Ajax()
.Model(model =>
{
model.Id(u => u.ID);
model.Field(u => u.CONTRACT_ID).DefaultValue(Model.ID);
model.Field(u => u.ID).DefaultValue(Guid.NewGuid());
})
.Create(create => create.Action("CreateCurClause", "Contracts"))
.Update(update => update.Action("UpdateCurClause", "Contracts"))
.Destroy(destroy => destroy.Action("DestroyCurClause", "Contracts")))
)
}
当我提交新的网格条目时，我收到ContractCurrencyClause模型的null:
public ActionResult CreateCurClause([DataSourceRequest]DataSourceRequest request, ContractCurrencyClause clause)
{
if(ModelState.IsValid)
{
}
return Json(new[] { clause }.ToDataSourceResult(request, ModelState));
}
我猜这是因为没有创建模型的新实例，当我按下网格工具栏中的Add按钮时，因为我看到JS错误:无法读取null的ID属性。
第二，我不知道如何临时绑定和存储Model.ContractCurrencyClauses，以便在用户提交主表单时传递整个集合。
EDIT 2:
ContractsController
public class ContractsController : Controller
{
//
// Static variables for Demo only
static ContractModel model;
static ICollection<ContractCurrencyClause> tmpContractCurrencyClauses { get; set; }
public ActionResult Index()
{
if (model == null)
{
model = new ContractModel();
tmpContractCurrencyClauses = new HashSet<ContractCurrencyClause>();
model.ContractCurrencyClauses = tmpContractCurrencyClauses;
}
model.ContractCurrencyClauses = tmpContractCurrencyClauses;
return View(model);
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(ContractCurrencyClause contract)
{
contract.CONTRACT_ID = new Guid();
tmpContractCurrencyClauses.Add(contract);
RouteValueDictionary routeValues = this.GridRouteValues();
return RedirectToAction("Index", routeValues);
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Update(ContractCurrencyClause contract)
{
tmpContractCurrencyClauses.Add(contract);
RouteValueDictionary routeValues = this.GridRouteValues();
return RedirectToAction("Index", routeValues);
}
}
Index.cshtml
@Html.HiddenFor(model=>model.ID)
@(Html.Kendo().Grid(Model.ContractCurrencyClauses)
.Name("ContractCurrencyClauses")
.ToolBar(toolbar => toolbar.Create())
.Columns(columns => {
columns.Bound(u => u.CONTRACT_ID).Hidden(true);
columns.Bound(u => u.CURRENCY);
columns.Bound(u => u.RATE);
columns.Command(command => { command.Edit(); command.Destroy(); });
})
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource =>
dataSource.Ajax()
.Model(model =>
{
model.Id(u => u.CONTRACT_ID);
//model.Id(u => u.CURRENCY); Kendo datasource does not support composite data keys.
model.Field(u => u.CONTRACT_ID).DefaultValue(Model.ID);
})
.Create(create => create.Action("Create", "Contracts"))
.Update(update => update.Action("Update", "Contracts"))
.Destroy(destroy => destroy.Action("DestroyCurClause", "Contracts")))
)

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(ContractCurrencyClause contract)
{
...
}
你试过把剑道网格放在表单之外吗?
根据剑道文档
Kendo UI MVC Grid在服务器内部使用表单元素已启用编辑。这意味着小部件不能放置在另一个小部件中表单元素，因为嵌套表单不是标准兼容。
还用剑道文档验证create, update方法签名。
如果你需要一次发送所有数据，你可以像这样序列化网格
var form data = JSON.stringify(dataSource.data());
我终于找到了一个更好的解决方案，我使用InCell编辑:
@(Html.Kendo().Grid(Model.ContractCurrencyClauses)
.Name("ContractCurrencyClauses")
.ToolBar(toolbar => { toolbar.Create(); })
.Columns(columns => {
columns.Bound(p => p.CONTRACT_ID).Hidden().ClientTemplate("#= CONTRACT_ID #" +
"<input type='hidden' name='ContractCurrencyClauses[#= index(data)#].CONTRACT_ID' value='#= CONTRACT_ID #' />"
);
columns.Bound(p => p.CURRENCY).ClientTemplate("#= CURRENCY #" +
"<input type='hidden' name='ContractCurrencyClauses[#= index(data)#].CURRENCY' value='#= CURRENCY #' />"
).EditorTemplateName("CurrencyDDL");
columns.Bound(p => p.RATE).ClientTemplate("#= RATE #" +
"<input type='hidden' name='ContractCurrencyClauses[#= index(data)#].RATE' value='#= RATE #' />"
);
columns.Command(command => { command.Destroy(); });
})
.Editable(editable => editable.Mode(GridEditMode.InCell).CreateAt(GridInsertRowPosition.Bottom))
.DataSource(dataSource =>
dataSource.Ajax()
.Model(model =>
{
model.Id(u => u.CONTRACT_ID);
model.Field(u => u.CONTRACT_ID).DefaultValue(Model.ID);
})
.ServerOperation(false)
)
)
<script>
function index(dataItem) {
var data = $("#ContractCurrencyClauses").data("kendoGrid").dataSource.data();
return data.indexOf(dataItem);
}
</script>
网格在我的主表单内，当我提交它时，我在控制器中收到ContractCurrencyClauses的整个列表。
