我使用以下方法创建自定义下拉字段,以将其插入到我的自定义表单中。现在我需要的是配置从管理面板的过滤器purpose.Like从管理面板这个字段,我将能够在文本框中编写一个过滤器,该过滤器将与ajax调用作为一个参数,从数据库中检索过滤数据。
我非常感谢你在这方面的帮助。
MyModule/Fields/MyCustomField.cs:
public class MyCustomField : ContentField {
public string SelectedValue {
get { return Storage.Get<string>(); }
set { Storage.Set(value); }
}

public class MyCustomFieldDriver : ContentFieldDriver<MyCustomField> {
// EditorTemplates/Fields/MyCustom.cshtml
private const string TemplateName = "Fields/MyCustom";
private static string GetPrefix(ContentField field, ContentPart part) {
// handles spaces in field names
return (part.PartDefinition.Name + "." + field.Name)
.Replace(" ", "_");
}
protected override DriverResult Display(ContentPart part, MyCustomField field, string displayType, dynamic shapeHelper) {
return ContentShape("Fields_MyCustom",
field.Name,
f => f.Name(field.Name)
.SelectedValue(field.SelectedValue));

在OrchardCMS中,我们可以创建自定义字段。每个字段都应该由管理员处理,以使其通用,为此,orchard提供了用户设置选项,使事情变得如此容易。因此,我们可以说,在orchardCMS中,当我们创建任何自定义字段时,我们也有一个设置部分。我们要做的就是创建一个setting文件夹,在该文件夹中我们需要创建一个setting类,比如DropDownFieldSetting.cs,在这里我们需要编写管理员需要将其视为设置的公共属性。设置/DropDownFieldSettings.cs
public class DropDownFieldSettings
{
public string Filter { get; set; }
}和设置文件夹settings/DropDownFieldEditorEvents.cs下的另一个类
public class DropDownFieldEditorEvents : ContentDefinitionEditorEventsBase
{
public override IEnumerable<TemplateViewModel>
PartFieldEditor(ContentPartFieldDefinition definition)
{
if (definition.FieldDefinition.Name == "DropDownCustomField")
{
var model = definition.Settings.GetModel<DropDownFieldSettings>();
yield return DefinitionTemplate(model);
}
}
public override IEnumerable<TemplateViewModel> PartFieldEditorUpdate(ContentPartFieldDefinitionBuilder builder, IUpdateModel updateModel)
{
var model = new DropDownFieldSettings();
if (updateModel.TryUpdateModel(model, "DropDownFieldSettings", null, null))
{
builder.WithSetting("DropDownFieldSettings.Filter", model.Filter);
yield return DefinitionTemplate(model);
}
}
}当管理员在filter Field中输入一些值时,将调用以下PartFieldEditorUpdate函数。在此函数中,此行保存您的设置
builder.WithSetting("DropDownFieldSettings.Filter",model.Filter);要全面了解这一切,我们可以查看OrcharCMS根目录下的模块文件夹下的Orchard.Fields模块。
