因此，我尝试使用Selection工厂在Episerver中创建两个下拉列表。但我想以某种方式连接它们。
像国家 - >地区，
我有没有办法在不使用DOJO的情况下做到这一点？或者我必须使用它吗？
[SelectOne(SelectionFactoryType = typeof(CustomCountryFactory))]
public string Country { get; set; }
[SelectOne(SelectionFactoryType = typeof(CustomCountryFactory1))]
public string Region{ get; set; }
public class CustomCountryFactory : ISelectionFactory
{
public IEnumerable<ISelectItem> GetSelections(ExtendedMetadata metadata)
{
var languages = new List<SelectItem>
{
new SelectItem() { Text = "All", Value = "All" },
new SelectItem() { Text = "Norway", Value = "Norway" },
new SelectItem() { Text = "Sweden", Value = "Sweden" },
};
return languages;
}
}
对于其他选择工厂，我不知道该怎么做。
EPiServer World上有一个类似问题的solution。它大量使用dojo。如果你真的需要2个单独的下拉菜单，你可以尝试一下。
由Anders Hattestad添加代码，用于在此处无法访问该文章的情况：
class DependedItem : ISelectItem
{
public string Parent { get; set; }
public object Value { get; set; }
public int Level { get; set; }
public string Text { get; set; }
public string Name { get { return Text; } }
}
public class ContinentCountryRegionSelectionFactory : ISelectionFactory
{
public IEnumerable<ISelectItem> GetSelections(ExtendedMetadata metadata)
{
var _geolocationProviderBase = ServiceLocator.Current.GetInstance<GeolocationProviderBase>();
var _localizationService = ServiceLocator.Current.GetInstance<LocalizationService>();
var list = new List<ISelectItem>();
foreach (var continentKey in _geolocationProviderBase.GetContinentCodes())
{
var continent = new DependedItem()
{
Value = continentKey,
Parent = "",
Level=0,
Text = _localizationService.GetString("/shell/cms/visitorgroups/criteria/geographiclocation/continents/" + continentKey)
};
list.Add(continent);
foreach (var countryKey in _geolocationProviderBase.GetCountryCodes(continentKey))
{
var country = new DependedItem()
{
Value = continentKey+"-"+ countryKey,
Parent= continentKey,
Level=1,
Text = _localizationService.GetString("/shell/cms/visitorgroups/criteria/geographiclocation/countries/" + countryKey)
};
list.Add(country);
foreach (var regionKey in _geolocationProviderBase.GetRegions(countryKey))
{
var region = new DependedItem()
{
Value = continentKey + "-" + countryKey+"-"+ regionKey,
Parent= continentKey + "-" + countryKey,
Level=2,
Text = regionKey
};
list.Add(region);
}
}
}
return list;
}
}
