保存Sitecore项目时,我试图显示一个弹出窗口以与用户进行交互。根据他们已更改的数据,我可能会显示一系列1或2个弹出窗口,询问他们是否要继续。我已经想出如何使用OnItemSaving管道。这很简单。我无法弄清楚的是如何显示弹出窗口并对用户的输入作出反应。现在我想我应该以某种方式使用Sitecore.Context.ClientPage.ClientResponse对象。这是一些代码,显示了我想要做的事情:
public class MyCustomEventProcessor
{
public void OnItemSaving(object sender, EventArgs args)
{
if([field criteria goes here])
{
Sitecore.Context.ClientPage.ClientResponse.YesNoCancel("Are you sure you want to continue?", "500", "200");
[Based on results from the YesNoCancel then potentially cancel the Item Save or show them another dialog]
}
}
}
我应该使用不同的方法吗?我看到还有ShowModalDialog和ShowPopUp以及ShowQuestion等。我似乎无法找到关于这些的任何文档。此外,我甚至不确定这是否是这样做的正确方法。

这个过程是这样的(我应该注意到我从未尝试过这个项目:保存事件,但是,我相信它应该有效):
item:saving
事件中,调用客户端管道中的对话处理器,并传递一组参数。以下是演示上述步骤的示例:
private void StartDialog()
{
// Start the dialog and pass in an item ID as an argument
ClientPipelineArgs cpa = new ClientPipelineArgs();
cpa.Parameters.Add("id", Item.ID.ToString());
// Kick off the processor in the client pipeline
Context.ClientPage.Start(this, "DialogProcessor", cpa);
}
protected void DialogProcessor(ClientPipelineArgs args)
{
var id = args.Parameters["id"];
if (!args.IsPostBack)
{
// Show the modal dialog if it is not a post back
SheerResponse.YesNoCancel("Are you sure you want to do this?", "300px", "100px");
// Suspend the pipeline to wait for a postback and resume from another processor
args.WaitForPostBack(true);
}
else
{
// The result of a dialog is handled because a post back has occurred
switch (args.Result)
{
case "yes":
var item = Context.ContentDatabase.GetItem(new ID(id));
if (item != null)
{
// TODO: act on the item
// Reload content editor with this item selected...
var load = String.Format("item:load(id={0})", item.ID);
Context.ClientPage.SendMessage(this, load);
}
break;
case "no":
// TODO: cancel ItemSavingEventArgs
break;
case "cancel":
break;
}
}
}
