C＃asp.net 4.5，MS visual studio 2012，nopcommerce CMS和Telerik。
我有以下代码部分：
剃刀查看 ..
<div>
@(Html.Telerik().Grid<Hroc.Plugin.Misc.ImageGallery.Models.PictureModel.myPictureModel>()
.Name("productpictures-grid")
.DataKeys(x =>
{
x.Add(y => y.Id).RouteKey("Id");
})
.Columns(columns =>
{
columns.Bound(x => x.PictureUrl)
.ClientTemplate("<a href='<#= PictureUrl #>' target='_blank'><img alt='<#= PictureId #>' src='<#= PictureUrl #>' width='150' /><a/>")
.ReadOnly();
columns.Bound(x => x.DisplayOrder);
columns.Bound(x => x.Description);
columns.Command(commands =>
{
commands.Edit().Text(T("Admin.Common.Edit").Text); // can i pass the id here? as well as delete and update?
commands.Delete().Text(T("Admin.Common.Delete").Text);
});
})
.Editable(x =>
{
x.Mode(GridEditMode.InLine);
})
.DataBinding(dataBinding =>
{
dataBinding.Ajax().Select("PictureList", "ImageGallery")
.Update("GalleryPictureUpdate", "ImageGallery")
.Delete("GalleryPictureDelete", "ImageGallery");
})
.EnableCustomBinding(true))
</div>
更新删除的控制器部分...
[GridAction(EnableCustomBinding = true)]
public ActionResult GalleryPictureUpdate(PictureModel.myPictureModel model, GridCommand command)
{
var galleryPicture = _galleryItemService.GetGalleryPictureById(model.Id);//get selected id?
if (galleryPicture == null)
throw new ArgumentException("No product picture found with the specified id");
galleryPicture.OrderNumber = model.DisplayOrder;
_galleryItemService.UpdateGallerytPicture(galleryPicture);
return PictureList(command);
}
[GridAction(EnableCustomBinding = true)]
public ActionResult GalleryPictureDelete(PictureModel.myPictureModel model, GridCommand command)
{
var galleryPicture = _galleryItemService.GetGalleryPictureById(model.Id);
if (galleryPicture == null)
throw new ArgumentException("No product picture found with the specified id");
var pictureId = galleryPicture.PictureID;
_galleryItemService.DeleteProductPicture(galleryPicture);
var picture = _pictureService.GetPictureById(pictureId);
_pictureService.DeletePicture(picture);
return PictureList(command);
}
我的服务类部分...
public virtual GalleryItem GetGalleryPictureById(int galleryPictureId)
{
if (galleryPictureId == 0)
return null;
return _ImageItemRepository.GetById(galleryPictureId);
}
public virtual void UpdateGallerytPicture(GalleryItem galleryPicture)
{
if (galleryPicture == null)
throw new ArgumentNullException("galleryPicture");
_ImageItemRepository.Update(galleryPicture);
//event notification
_eventPublisher.EntityUpdated(galleryPicture);
}
public virtual void DeleteProductPicture(GalleryItem galleryPicture)
{
if (galleryPicture == null)
throw new ArgumentNullException("productPicture");
_ImageItemRepository.Delete(galleryPicture);
//event notification
_eventPublisher.EntityDeleted(galleryPicture);
}
从提供的代码中，它全部位于nopcommerce中的新插件（类库）中。
基本上，当您配置插件部分时，显示的视图显示图像列表，然后您可以将新图像上载到列表中，然后显示该列表。这部分工作正常。
“编辑”命令允许Telerik命令选项起作用，因此您可以更改显示顺序和说明。但是，当您要更新或删除其抛出时，异常“找不到ID”。
这里有什么我想念的吗？我相信它，因为我实际上并没有获得特定的ID并将其传递给我的控制器方法（发生错误的地方）。
任何帮助都会很棒！
更新：02/12/2013按要求获取代码以获取图像列表。
控制器
[HttpPost, GridAction(EnableCustomBinding = true)]
public ActionResult PictureList(GridCommand command)
{
if (!_permissionService.Authorize(StandardPermissionProvider.ManagePlugins))
return Content("Access denied");
var nop_Image = _galleryItemService.Fetch(); //my image
var Nop_ImagesModel = nop_Image
.Select(x =>
{
var nop_gModel = new PictureModel.myPictureModel()
{
PictureId = x.Id,
PictureUrl = _pictureService.GetPictureUrl(x.PictureID),
DisplayOrder = x.OrderNumber,
Description = x.Description
};
return nop_gModel;
})
.ToList();
var model = new GridModel<PictureModel.myPictureModel>
{
Data = Nop_ImagesModel,
};
return new JsonResult
{
Data = model
};
}
根据要求更新：2013年12月2日
[GridAction(EnableCustomBinding = true)]
public ActionResult GalleryPictureDelete(PictureModel.myPictureModel model, GridCommand command)
{
var galleryPicture = _galleryItemService.GetGalleryPictureById(model.PictureId);
if (galleryPicture == null)
throw new ArgumentException("No product picture found with the specified id");
var pictureId = galleryPicture.PictureID;
_galleryItemService.DeleteProductPicture(galleryPicture);
var picture = _pictureService.GetPictureById(pictureId);
_pictureService.DeletePicture(picture);
return PictureList(command);
}
视图

columns.Bound(x => x.Description);
columns.Command(commands =>

答案 0 :(得分：2)
您唯一需要做的就是分配Id而不是pictureId并保留您的第一个代码
.DataKeys(x =>
{
x.Add(y => y.Id).RouteKey("Id");
})
var nop_gModel = new PictureModel.myPictureModel()
{
Id = x.Id,//Changed as you are getting picture by Id
PictureUrl = _pictureService.GetPictureUrl(x.PictureID),
DisplayOrder = x.OrderNumber,
Description = x.Description
};
var galleryPicture = _galleryItemService.GetGalleryPictureById(model.Id);
