在Page Editor模式下添加自定义按钮

       在Sitecore中，我们已经很熟悉使用Page Editor模式来编辑页面内容。但当在Page Editor模式下新建节点时，Sitecore只能新建一个Item，除了设置过Standard Value值的字段外，不能立即对Item的字段赋值。本文我们就通过添加自定义按钮的方式，实现新建一个item后立即修改item字段的功能。

       1. 在项目中新建一个类，用来实现编辑字段的弹出窗功能：

internal class FieldEditInfosCommand : FieldEditorCommand
{
protected override PageEditFieldEditorOptions GetOptions(ClientPipelineArgs args, NameValueCollection form)
{
ItemUri uri = ItemUri.Parse(args.Parameters["uri"]);
Item item = Database.GetItem(uri);
return new PageEditFieldEditorOptions(form, new List<FieldDescriptor>
{
new FieldDescriptor(item, "Title"),
})
{
Title = "Info Field Editor",
Text = "Make changes to info item fields",
Icon = "people/16x16/cubes_blue.png"
};
}

protected new void StartFieldEditor(ClientPipelineArgs args)
{
HttpContext current = HttpContext.Current;
if (current != null)
{
var page = current.Handler as Page;
if (page != null)
{
NameValueCollection form = page.Request.Form;
if (form != null)
{
if (!args.IsPostBack)
{
string javascript = "scSave()";
SheerResponse.Eval(javascript);
SheerResponse.ShowModalDialog(GetOptions(args, form).ToUrlString().ToString(), "720", "480",
string.Empty, true);
args.WaitForPostBack();
return;
}
if (args.HasResult)
{
Item item = null;
foreach (FieldDescriptor current2 in PageEditFieldEditorOptions.Parse(args.Result).Fields)
{
Item item2 = Context.ContentDatabase.GetItem(current2.ItemUri.ToDataUri());
if (item == null &&
item2.TemplateID.ToString().Equals("{2AFEDA7B-2D79-4778-9CB4-6E090667C001}"))
{
item = item2;
}
using (new SecurityDisabler())
{
item2.Editing.BeginEdit();
item2[current2.FieldID] = current2.Value;
item2.Editing.EndEdit();
}
}
}
}
}
}
}
}

       2. 新建一个类，用来实现添加一个item的功能：

      

class CreateNewEditFrameCommand : New
{
public override void Execute(CommandContext context)
{
context.Parameters["itemid"] = context.Parameters["id"];
base.Execute(context);
}
protected new void Run(ClientPipelineArgs args)
{
Assert.ArgumentNotNull(args, "args");
string itemPath = args.Parameters["itemid"];
Language language = Language.Parse(args.Parameters["language"]);
Item itemNotNull = Client.GetItemNotNull(itemPath, language);
if (args.IsPostBack)
{
if (args.HasResult)
{
string[] array = args.Result.Split(new char[]
{
','
});
string masterName = array[0];
string name = array[1];
Database database = Factory.GetDatabase("master");
BranchItem branchItem = database.Branches[masterName, itemNotNull.Language];
Assert.IsNotNull(branchItem, typeof(BranchItem));
this.ExecuteCommand(itemNotNull, branchItem, name);
Client.Site.Notifications.Disabled = true;
Item item = Context.Workflow.AddItem(name, branchItem, itemNotNull);
Client.Site.Notifications.Disabled = false;
if (item != null)
{
this.PolicyBasedUnlock(item);
item.Editing.BeginEdit();
CommandContext commandContext = new CommandContext(item);
commandContext.Parameters.Add("uri", item.Uri.ToString());
Command command = CommandManager.GetCommand("fieldedit:editinfo");
command.Execute(commandContext);
return;
}
}
}
else
{
if (!itemNotNull.Access.CanCreate())
{
SheerResponse.Alert("You do not have permission to create an item here.", new string[0]);
return;
}
UrlString urlString = ResourceUri.Parse("control:Applications.WebEdit.Dialogs.AddMaster").ToUrlString();
itemNotNull.Uri.AddToUrlString(urlString);
SheerResponse.ShowModalDialog(urlString.ToString(), true);
args.WaitForPostBack();
}

}
}

        3. 在Commands.config文件中注册新command：

        <command name="fieldedit:createinfo" type="Demo.Services.CreateNewEditFrameCommand, Demo.Services"/>

      <command name="fieldedit:editinfo" type="Demo.Services.FieldEditInfosCommand, Demo.Services"/>

        4. 登陆到sitecore后台，切换到core数据库，在/sitecore/content/Applications/WebEdit/Custom Experience Buttons下面，以“/sitecore/templates/System/WebEdit/WebEdit Button”为模板新建一个item，并修改其属性：

       


       5. 保存，切换回master数据库。在需要的sublayout上添加该按钮。

       6. 打开Page Editor ，测试该按钮。
