无法使用Web服务更新查找字段 [英] Unable to update lookup Field using webservice

问题描述

我已经阅读了许多解决方案，但还无法使用Web服务在列表中填充查找列.

I have read many of the solutions but I haven't yet been able to populate a lookup column in a list using web service.

我在同一站点上有一些名为"ApplicationFamilyList"的应用程序族的列表.

I have a list of some application families named "ApplicationFamilyList" on the same site.

在我当前的列表中，我有一列名为"Appfamily"的类型查找，该列引用了"ApplicationFamilyList".我希望使用webservice-UpdateListItems()方法在该列中插入一些应用程序系列.但是，我 无法填充此列中的项目，可能是由于参考所致.以下是我以声明方式生成的XML.请提出我需要添加到< Field>的哪些属性标记以获取结果.
      

In my current list I have a column named "Appfamily" of type lookup which has reference to "ApplicationFamilyList". I wish to insert some application families in that column using webservice - UpdateListItems() method. however, I am unable to populate items in this column maybe due to reference. below is the XML I am generating declaratively. Please suggest what attributes I need to add to <Field> tag to get the results.
       

string strBatch = 	
"<Method ID='1' Cmd='New'>
<Field Type='Text' DisplayName='Application_Name' ID='{b475c14a-46ae-495f-b381-d264c2f51a45}'Name='Application_Name'>testApplication1</Field>
<Field Type='Lookup' DisplayName='Application_Family' ID='{bbe858fd-0c8e-406b-a278-83cac0b58d1b}' Name='Application_Family'>testfamilyfamily1</Field>
</Method>";
        

XmlDocument xmlDoc = new System.Xml.XmlDocument();
System.Xml.XmlElement elItem = xmlDoc.CreateElement("Batch");
elItem.SetAttribute("OnError", "Continue");
elItem.InnerXml = strBatch.ToString();
string ListName = "Dev Application Name Lookup";
UpdateSPList.UpdateListItems(ListName, elItem);

提前谢谢！

推荐答案

请在批处理命令中使用查找ID更新查找字段，如下所示:

Please update the lookup field with Lookup Id In the batch Command like below:

<Batch OnError=’Continue’> 
         <Method ID=’1’ Cmd=’New’> 
                <Field Name=’OrderDate’ >2007-1-21</Field> 
                <Field Name=’CustomerID’ Type=’LookUp’  LookUpID=’True’ >2</Field> 
         </Method> 
</Batch>
