如何以编程方式更新infopath表单库项目字段？

发布于 2024-09-19 08:23:54 字数 960 浏览 2 评论 0原文

我成功地使用共享点对象模型从 infopath 更新库项目的字段之一（布尔类型），就像它是列表项目一样。

但对于另一个文本类型的字段，相同的代码只会被执行，但不会更改字段值！！！！

我正在使用以下代码，该代码适用于该布尔字段，但适用于 string 类型的另一个字段，不确定为什么它不起作用。有什么想法吗？

SPSecurity.RunWithElevatedPrivileges(delegate()

{ 
SPWeb web;

SPSite site = new SPSite("http://sharepointsite"); 
web = site.OpenWeb();

SPList formLibList = web.Lists["FormLibraryName"];

SPQuery query = new SPQuery(); query.Query = "<Where><Eq><FieldRef Name='Title' /><Value Type='Text'>" + titleName + "</Value></Eq></Where>"; 
web.Site.WebApplication.FormDigestSettings.Enabled = false;

web.AllowUnsafeUpdates = true; 
SPListItemCollection col = formLibList.GetItems(query);

if (col.Count > 0) 
{

col[0]["CustomerName"] = "test customer name"; 
col[0].Update();

}

web.Site.WebApplication.FormDigestSettings.Enabled = true; web.AllowUnsafeUpdates = false; 
});

谢谢，

I was successfully able to update one of the fields (which was of type boolean) from infopath for library item using sharepoint object Model as if it was a list item.

But for another field which is of type text, the same code just gets executed but does not change the field value !!!!

I am using following code, which works for that boolean field but for another field of type string , not sure why it is not working. Any idea ?

SPSecurity.RunWithElevatedPrivileges(delegate()

{ 
SPWeb web;

SPSite site = new SPSite("http://sharepointsite"); 
web = site.OpenWeb();

SPList formLibList = web.Lists["FormLibraryName"];

SPQuery query = new SPQuery(); query.Query = "<Where><Eq><FieldRef Name='Title' /><Value Type='Text'>" + titleName + "</Value></Eq></Where>"; 
web.Site.WebApplication.FormDigestSettings.Enabled = false;

web.AllowUnsafeUpdates = true; 
SPListItemCollection col = formLibList.GetItems(query);

if (col.Count > 0) 
{

col[0]["CustomerName"] = "test customer name"; 
col[0].Update();

}

web.Site.WebApplication.FormDigestSettings.Enabled = true; web.AllowUnsafeUpdates = false; 
});

Thanks,

Nikhil

我必须声明 SPListItem 并设置它，而不是直接修改列表项集合。

这不是您问题的答案（您自己已经找到了解决方案），但您可能希望将 SPSite 和 SPWeb 对象放在 using 块中。在您的示例代码中，您没有处理它们，这会导致内存泄漏。正确的方法是这样的：

SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite site = new SPSite("http://sharepointsite"))
    {
        using (SPWeb web = site.OpenWeb())
        {
            // the rest of your code
        }
    }
});

It's not an answer to your question (you already found the solution yourself), but you may want to put your SPSite and SPWeb objects in a using block. In your example code you are not disposing them, which results in a memory leak. The correct way would be like this:

SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite site = new SPSite("http://sharepointsite"))
    {
        using (SPWeb web = site.OpenWeb())
        {
            // the rest of your code
        }
    }
});
