我的剑道网格正在复制记录 [英] My kendo grid is duplicating records
问题描述
我的应用程序中有一个剑道gri.
I have a kendo gri in my application.
这是一张照片.
这是代码
@(Html.Kendo().Grid<TekstenViewModel.Tekst>()
.Name("Grid")
.Columns(columns =>
{
columns.Template(@<text></text>).ClientTemplate("<input type='checkbox'/>").Width(10).Hidden(!Model.Administrator);
columns.Bound(product => product.RESOURCE_SET_NAAM).ClientTemplate("#= RESOURCE_SET_NAAM#");
columns.Bound(product => product.Naam).ClientTemplate("#= Naam#");
columns.Bound(product => product.Waarde).ClientTemplate("<div id='editorDiv'><div class='input'>#if(Waarde){# #if(Waarde.length>100){# # var myContent =Waarde; # # var dcontent = myContent.substring(0,100); # <span>#=kendo.toString(dcontent)#</span> #}else{# <span>#=Waarde#</span> #}# #}#</div><div class='editor'>" +
Html.WebCore().LinkButton(type: ButtonType.Edit, htmlAttributes: new { onclick = "openPopupDemo('#: Waarde #', '#: ID #', 'Waarde')" }));
columns.Bound(product => product.Opmerking).ClientTemplate("<div id='editorDiv'><div class='input'>#if(Opmerking){# #if(Opmerking.length>100){# # var myContent =Opmerking; # # var dcontent = myContent.substring(0,100); # <span>#=kendo.toString(dcontent)#</span> #}else{# <span>#=Opmerking#</span> #}# #}#</div><div class='editor'>" +
Html.WebCore().LinkButton(type: ButtonType.Edit, htmlAttributes: new { onclick = "openPopupDemo('#: Opmerking #', '#: ID #', 'Opmerking')" }));
columns.Template(@<text></text>).ClientTemplate("<div id='deleteDiv'><div class='delete'><a class=\"delete iconBtn\" onclick=\"deleteResourceItem(#: ID #, '#: Naam #')\"></a></div></div>").Width(10).Hidden(!Model.Administrator);
})
.Pageable()
.Sortable()
.Filterable()
.Events(events => events.Edit("onCellEdit").DataBinding("onDataBinding").DataBound("onDataBound"))
.Groupable()
.Resizable(a => a.Columns(true))
.Navigatable()
.Editable(editable => editable.Mode(GridEditMode.InCell).DisplayDeleteConfirmation(false))

})
.Create(create => create.Action(MVC.BeheerTeksten.ActionNames.ResourceItems_Create, MVC.BeheerTeksten.Name).Data("onCreateAdditionalData"))
.Read(read => read.Action(MVC.BeheerTeksten.ActionNames.ResourceItems_Read, MVC.BeheerTeksten.Name, new { setID = Model.SetID }).Data("onReadAdditionalData"))
.Update(update => update.Action(MVC.BeheerTeksten.ActionNames.ResourceItems_Update, MVC.BeheerTeksten.Name).Data("onAdditionalData"))
.Destroy(destroy => destroy.Action(MVC.BeheerTeksten.ActionNames.ResourceItems_Delete, MVC.BeheerTeksten.Name))
)
)
除了创建新记录时，网格工作正常.它调用创建方法，将记录保存在数据库中，等等，没问题.
The grid works just fine, except when I create a new record. It calls the method to create, saves the record on the database, etc, no problem.
但是当我返回视图时，我刚刚添加的记录将作为插入表中的第一条记录的副本出现.
But when I return to the view, the record I just add appears as a duplicate of the first record inserted in the table.
是的，我知道这听起来很奇怪，但这是事实.我已经尝试过几次使用不同的值，但是我总是得到相同的结果.
Yes, I know it sounds strange but it's true. I've tried several times with different values, but I always get the same result.
所有新记录都显示为添加到网格中的第一条记录的重复.当然，如果我刷新页面，则数据正确.
Every new record is shown as a duplicate of the first record added to the grid. Off course, if I refresh the page, the data is correct.
这是一个例子. 添加新记录之前的网格.
Here's an example. The grid before adding a new record.
插入新记录后的网格.
最后，保存更改后，我得到了.如果刷新页面，则数据正确.
Finally, after saving changes, I get this. If I refresh the page, the data is correct.
这是我的创建方法.

return Json(resourceItems.ToDataSourceResult(request, ModelState));
}
推荐答案
问题应该是您没有从create操作中返回带有product.ID的Json
The problem should be that you are not returning a Json with product.ID back from your create action
Create(create => create.Action(MVC.BeheerTeksten.ActionNames.ResourceItems_Create, MVC.BeheerTeksten.Name).Data("onCreateAdditionalData"))
需要返回，添加的商品带有model.Id(product => product.ID);
Need to Return , the added item with the model.Id(product => product.ID);
Kendo网格在由ID创建时跟踪物料，因此您需要将其提供回数据源
Kendo grid tracks the Items when created by the ID so you need to provide it back to the DataSource
