我有一个mvc4 razor视图，包含一个带有详细模板的Kendo mvc网格，这些模板也是Kendo Tabstrip每个标签内的Kendo mvc网格。
每个细节网格都通过主网格的唯一ID链接到主网格。 当列是文本时，所有网格都可以毫无问题地呈现。
但是，一旦我开始自定义某些列，即用EditorTemplate替换文本列，那么网格就不会再渲染了。我在一些列中使用了ForeignKeyColumn，但是由于某些列的记录大小，我必须使用EditorTemplate来自定义源并限制每次传递给客户端的记录数。
这是我的视图代码。

这是我的两个EditorTemplate。

function valueMapper(options) {
$.ajax({

data: convertValues(options.value),
success: function (data) {
options.success(data);
}
});
}
function convertValues(value) {
var data = {};
value = $.isArray(value) ? value : [value];
for (var idx = 0; idx < value.length; idx++) {
data["values[" + idx + "]"] = value[idx];
}
return data;
}
</script>
@(Html.Kendo().DropDownListFor(m => m)
.HtmlAttributes(new { id = "LocationDDL#=AssetSubTypeID#" })

我发现导致问题的行都与使用EditorTemplate有关。一旦我对这两行进行评论，网格就会再次加载。
columns.Bound（c =＆gt; c.AssetSubType）。标题（＆＃34; SubType＆＃34;）。ClientTemplate（＆＃34; \＃= AssetSubType.SubType \＃＆＃34;）。EditorTemplateName（ ＆＃34; SubTypeEditor＆＃34）;
columns.Bound（c =＆gt; c.Location）。标题（＆＃34;位置＆＃34;）。ClientTemplate（＆＃34; \＃= Location.Asset \＃＆＃34;）。EditorTemplateName（ ＆＃34; LocationEditor＆＃34）;
根据Kendo的文档，我已经通过在＃的每个实例之前放入两个（2）\反斜杠（屏幕只显示一个，但我在代码中放了两个）来逃避#hash但网格仍然没有渲染。
但是，如果我拿出这些细节网格并将它们放在一个新视图上，它们就会起作用。
我也试图为DropDownList分配唯一的名称，但它似乎没什么帮助。
非常感谢任何帮助。
