Question

我在MemberType下创建了一个名为＆＃34; testField＆＃34;它使用自定义DataType下拉列表，其中包含2个值（Employee和Subcontractor）。我希望会员能够选择一个，提交表格并将他们的选择存储在这个属性下，但我似乎无法弄明白。

是否可以在后端手动更改选择的同时执行此操作？

这是我的代码......

Answer 1

您的具体问题有两个方面：

1）您要将m.getProperty("testField")设置为DropDownList的实例而不是SelectedValue

2）正如对问题的评论所述，您的硬编码DropDownList值不匹配以及DataType属性的Umbraco testField中存储的值。

您可以通过将DropDownList与Umbraco调用的内容绑定来更有力地解决第二个问题存储在PreValues数据类型上的testField将确保DropDownList中的可用选项匹配DataType

上定义的选项

编写本文时，PreValues将作为XML片段存储在数据类型定义中格式如下：

<preValues>
    <preValue id="1">Option 1</preValue>
    <preValue id="2">Option 2</preValue>
    <preValue id="3">Option 3</preValue>
</preValues>

以编程方式检索这些有点笨重（IMO）;首先，您需要获取Id的{{1}} 将鼠标悬停在umbraco界面的DataType上并查看状态栏（您应该会看到DataType javascript:openDataType(1111) 1111之类的内容。

接下来调用Id方法，传入上面获得的umbraco.library.GetPreValues()。这种方法返回Id，您可以使用该XPathNodeIterator以适合您需要的方式获取值，例如创建可以绑定到Dictionary<string,string>的{{1}}。以下示例取自Damiaan Peeters blog 并且稍微适应了。

DropDownList

然后在您的代码中，您可以执行以下操作：

private static Dictionary<string, string> GetPreValues(int dataTypeId)
{
    XPathNodeIterator preValueRootElementIterator = umbraco.library.GetPreValues(dataTypeId);
    preValueRootElementIterator.MoveNext(); //move to first 
    XPathNodeIterator preValueIterator = preValueRootElementIterator.Current.SelectChildren("preValue", "");
    var retVal = new Dictionary<int, object>();

    while (preValueIterator.MoveNext())        
        retVal.Add(preValueIterator.Current.GetAttribute("id", ""), preValueIterator.Current.Value);

    return retVal;
}

根据下拉列表选择值更新MemberType属性
