Update approval Status through SharePoint Web Service

The SharePoint list that is enabled for approval, if we modify one of the approved list items through the object model, the update causes the list item to return to the pending state. However, the object model has a strong systemupdate, can be quietly modify the list items. However, if you are making changes through the Lists.asmx updatelistitems in the SharePoint Web service, you are not so lucky.

Referencing the description in the SharePoint SDK: the Cmd property of each method element determines what action is performed on the project by specifying one of the following values:

*delete--Deletes an item.

*new--Creates an item.

*update--modifies the item.

For what we said above, CMD can only write "Update".

The common wording on the Web is as follows:

1　<Batch　OnError="Continue">
2　<Method　ID="1"　Cmd="Update">
3　<FIEld　Name="ID">3634</Field>
4　<Field　 Name="FileRef">3634;#Lists/Fichesroyjs/3634_.000</Field>
5　<Field　Name="_ModerationStatus">0</Field>
6　</Method>
7　</Batch>

Modify the approval status of a document library (invalid)

However, the results of this operation are always pending. Even the <field name= "_moderationstatus" >0</Field> is included in the update. Perhaps you will think of the update two times, here can directly tell you the results, or to be determined.

So how do you add or modify list items and ensure approval status is approved?

The answer was finally found on the forum. When you perform approval through a Web service, you should use the "moderate" command instead of the "Update" command.

The wording is as follows:

1　<Batch>
2　<Method　ID='1'　 Cmd='<strong>Moderate</strong>'>
3　<Field　Name='ID'>6</Field>
4　<Field　 Name='<strong>_ModerationStatus</strong>'>0</Field> ;
5　</Method>
6　</Batch>

Modify the approval status of a list item with ID 6 in a list as approved

Attached below is a complete list of updates and automatically approves the example. One of the most important is the cmd= "moderate" sentence:

01　public　static　XmlNode　UpdateListItemApprove()
02　{
03　listservice.Lists　listProxy　=　new　listservice.Lists();
04　string　xml　=　"<Batch　OnError='Continue'><Method　 ID='1'　Cmd='Moderate'><FIEld　 Name='ID'>167</Field><Field　Name='PublishToHomePage'　 Type='Boolean'>1</Field><Field　Name=\"_ModerationStatus\" 　>0</Field></Method></Batch>";
05　XmlDocument　doc　=　new　XmlDocument();
06　doc.LoadXml(xml);
07　XmlNode　batchNode　=　doc.SelectSingleNode("//Batch");
08　listProxy.Url　=　"http://puremoss/it/_vti_bin/lists.asmx";
09　listProxy.UseDefaultCredentials　=　true;
10　XmlNode　resultNode　=　listProxy.UpdateListItems("通知",　 batchNode);
11　return　resultNode;
12　}
