好的......我花了太多时间在这个上面挣扎，所以我将它传递给了专家 - >你。ASP.NET MVC Rails的Telerik Rad Grid Razor视图引擎 - DetailView最初没有填充
我非常简单的ASP.NET MVC（v3 with Razor View Engine）页面使用Telerik Rad Grid控件来显示一些类型列表，然后我在网格的DetailsView中显示相关的代码。
做人口很容易。我有我的TypeCodeList类型的ViewModel并将其发送到强类型的视图来填充网格。这工作良好...和网格看起来很棒 - 感谢Telerik。但是，我添加了DetailsView，然后以相同的方式填充子类型代码。坏消息是，当我的网格填充时，我选择左侧的三角形展开树并查看子记录，没有任何内容。但是，如果我选择网格底部的“刷新”按钮，那么我可以打三角形和子记录显示。
因此（总之），子记录不显示在初始加载。只有当我选择网格的AJAX刷新时，我才会得到这些孩子。否则，它按要求工作。
我一直在试图看看我是否可以编程的方式在页面加载时通过javascrip启动刷新。或者如果我可以在没有首先进行刷新的情况下选择自己填充的东西 - 那会更好。
下面是我的代码：
相关的控制器代码（我已经采取了更新，删除，插入记录和数据访问方法）
[HandleErrorWithElmah]
public partial class HostController : Controller
{
/// <summary>
/// Index - Home for HostController
/// </summary>
/// <returns></returns>
public ActionResult Index()
{
return View();
}
#region Type List Section
/// <summary>
/// Gets the list of TypeLists - yea...say that again
/// </summary>
[GridAction]
public ActionResult TypeCodeList()
{
var model = GetActiveTypeLists();
// Get all of the type lists and send them to the view
return View(model);
}
/// <summary>
/// The ajaxified Select
/// </summary>
/// <returns></returns>
[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult _TypeCodeList()
{
var model = GetActiveTypeLists();
return Json(new GridModel(model));
}
/// <summary>
/// Simply a wrapper to get all of the current type list values.
/// </summary>
/// <returns></returns>
private IEnumerable<TypeCodeListViewModel> GetActiveTypeLists()
{
var model = from p in entityRepository.Find<TypeList>(p => p.IsActive == true)
select new TypeCodeListViewModel
{
TypeListId = p.TypeListId,
Name = p.Name,
Description = p.Description,
IsActive = p.IsActive
};
return model;
}
#endregion
#region Type Code Section
[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult _TypeCodeForTypeListAjax(int typeListId)
{
var model = GetActiveTypeCodes(typeListId);
return Json(new GridModel(model));
}
/// <summary>
/// Simply a wrapper to get all of the current type Code values.
/// </summary>
/// <returns></returns>
private IEnumerable<TypeCodeViewModel> GetAllActiveTypeCodes()
{
var model = from p in entityRepository.Find<OurLeaguePlay.Models.TypeCode>(p => p.IsActive == true).OrderBy(ord => ord.CodeName)
select new TypeCodeViewModel
{
TypeCodeId = p.TypeCodeId,
TypeListId = p.TypeListId,
CodeName = p.CodeName,
CodeValue = p.CodeValue,
Description = p.Description,
IsActive = p.IsActive
};
return model;
}
/// <summary>
/// Simply a wrapper to get all of the current type Code values.
/// </summary>
/// <returns></returns>
private IEnumerable<TypeCodeViewModel> GetActiveTypeCodes(int typeListId)
{
var model = from p in entityRepository.Find<OurLeaguePlay.Models.TypeCode>(p => p.IsActive == true &&
p.TypeListId == typeListId).OrderBy(ord => ord.CodeName)
select new TypeCodeViewModel
{
TypeCodeId = p.TypeCodeId,
TypeListId = p.TypeListId,
CodeName = p.CodeName,
CodeValue = p.CodeValue,
Description = p.Description,
IsActive = p.IsActive
};
return model;
}
#endregion
}
这是我查看代码： （我已经采取了所有我失败的JavaScript的尝试，试图迫使在页面加载负荷）
@model IEnumerable<TypeCodeListViewModel>
@using Telerik.Web.Mvc.UI
@using Telerik.Web.Mvc
@using OurLeaguePlay.ViewModels
@{Html.Telerik().Grid<TypeCodeListViewModel>(Model)
.Name("TypeLists")
.DetailView(details => details.ClientTemplate(
Html.Telerik().Grid<TypeCodeViewModel>()
.Name("TypeCode_<#= TypeListId #>")
.DataKeys(keys => keys.Add(k => k.TypeCodeId))
.Columns(columns =>
{
columns.Bound(o => o.CodeName).Width(40);
columns.Bound(o => o.CodeValue).ReadOnly(true).Width(40);
columns.Bound(o => o.Description).Width(100);
})
.DataBinding(dataBinding =>
{
dataBinding.Ajax().Select("_TypeCodeForTypeListAjax", "Host", new { typeListId = "<#= TypeListId #>" })
.Enabled(true);
}
)
.Pageable()
.Sortable()
.NoRecordsTemplate("No Type Codes exist for the selected Type List")
.ToHtmlString()
)
)
.DataKeys(keys => keys.Add(k => k.TypeListId))
.Columns(columns =>
{
columns.Bound(o => o.Name).Width(100);
columns.Bound(o => o.Description).Width(150);
columns.Command(commands =>
{
commands.Edit().ButtonType(GridButtonType.Image);
commands.Delete().ButtonType(GridButtonType.Image);
}
).Width(30);
})
.DataBinding(dataBinding =>
{
dataBinding.Ajax().Select("_TypeCodeList", "Host")
.Update("UpdateTypeList", "Host")
.Insert("InsertTypeList", "Host")
.Delete("DeleteTypeList", "Host")
.Enabled(true);
dataBinding.Server().Select("TypeCodeList", "Host", new { ajax = ViewData["ajax"] });
}
)
.Editable(editable => editable.Enabled(true).Mode(GridEditMode.InLine))
.Pageable(page => page.PageSize(10))
.Sortable()
.Selectable()
.Scrollable(scroll => scroll.Enabled(false))
.NoRecordsTemplate("No Type Lists can be retrieved from the database")
.ToolBar(commands => commands.Insert())
.Render();
}
最后......这里的视图模型类：
public class TypeCodeListViewModel
{
[ScaffoldColumn(false)]
public int TypeListId { get; set; }
[Required(ErrorMessage = "Required")]
[StringLength(25, ErrorMessage = "Max Length is 25")]
public string Name { get; set; }
[Required(ErrorMessage = "Required")]
[StringLength(25, ErrorMessage="Max Length is 25")]
public string Description { get; set; }
[ScaffoldColumn(false)]
public bool IsActive { get; set; }
}
public class TypeCodeViewModel
{
[ScaffoldColumn(false)]
public int TypeCodeId { get; set; }
[ScaffoldColumn(false)]
public int TypeListId { get; set; }
[Required(ErrorMessage = "Required")]
[StringLength(25, ErrorMessage = "Max Length is 25")]
[DisplayName("Name")]
public string CodeName { get; set; }
[Required(ErrorMessage = "Required")]
[StringLength(25, ErrorMessage = "Max Length is 25")]
[DisplayName("Value")]
public string CodeValue { get; set; }
[StringLength(500, ErrorMessage = "Max Length is 500")]
public string Description { get; set; }
[ScaffoldColumn(false)]
public bool IsActive { get; set; }
}
