以编程方式创建的列表项始终是一个文件夹 [英] Programmatically created list item is always a folder

问题描述

你好

我通过编程方式创建列表项时遇到问题. szenario:

I have a problem by creating a list item programmatically. The szenario:

-2个具有自定义内容类型和字段的列表(Changes-CustomDocSet库，Risks-Custom任务列表)

- 2 Lists (Changes-CustomDocSet Lib, Risks-Custom Task List) with custom content types and fields

-更改列表的新/编辑表单包括一个DataGrid，其中显示了风险"列表中的项目

- The new/edit form of the Changes List includes a DataGrid witch shows the items of the Risks list

将显示我在风险"列表中手动创建的所有项目.现在，我可以使用添加"按钮从更改"列表的新/编辑表单中添加其他项.我可以插入，但该项目未显示在网格中.

All items, i created manually in the Risk list are shown. Now I can add additional items from the new/edit form of the Changes list using the Add button. I can insert but the item is not shown in the grid.

为什么?如果我查看风险"列表，则可以看到插入的项目，但它不是项目，而是显示为文件夹类型.

Why? If i look into my Risk list, I can see the inserted item, but it is not a item, it is shown as folder type.

这是我添加项目的实现:

This is my implementation to add the item:

SPListItem item = list.Items.Add();
item["ChangeReference"] = "1";
item[SPBuiltInFieldId.Title] = title.Text;
item["Title"] = title.Text;
item["Risk"] = risk.Text;
item["Probability"] = probability.Text;
item.Update();

列表定义只有我的自定义内容类型:

The List Definition only has my custom content type:

<List xmlns:ows="Microsoft SharePoint" Title="Risks" FolderCreation="FALSE" Direction="$Resources:Direction;" EnableContentTypes="TRUE" Url="Lists\Risks" BaseType="0" xmlns="http://schemas.microsoft.com/sharepoint/">
  <MetaData>
    <ContentTypes>
      <ContentTypeRef ID="0x0108009007F1B9465C48F2AE80B77CC58A4AA7" />

    </ContentTypes> ...

    </ContentTypes> ...

手动创建的项可以在list.Items中找到，程序创建的项始终在list.folders中创建，但是我不知道为什么以及如何更改它?我需要普通物品，而不是文件夹.

The manually created item can be found within list.Items, the programmitcally created item are always created in list.folders, but I don't know why and how to change that? I need normal items, not folders.

有想法的人吗?

推荐答案

风险列表"的内容类型"的详细设置是什么?

What is the detailed setting of Content Type for the Risk List ?

我已经测试过的C#代码段，它将在任务列表中创建一个项目.请尝试删除自定义内容类型，然后再试一次以查看创建的项目是否可以使用.

The C# code snippet I have tested, it will create a item in the task list. Please try to remove the custom Content Type and then try again to see if the item created will work. 

还要尝试将EnableFolderCreation属性设置为false并测试问题是否仍然存在:

And also try to set EnableFolderCreation properties to false and test if the issue still existed:

谢谢
