Question

Although I specify a ViewFields element in my sharepoint list service’s GetListItems query, all fields are returned. The following code builds the request:

XmlDocument xmlDoc = new System.Xml.XmlDocument();
XmlNode query = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode viewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode queryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");    

... set query ...

viewFields.InnerXml = "<FieldRef Name='LinkFilename' /><FieldRef Name='FileDirRef' /><FieldRef Name='FileLeafRef' />";            

queryOptions.InnerXml = "<IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns><DateInUtc>TRUE</DateInUtc><Folder>Resource Management Tools</Folder><ViewAttributes Scope='Recursive' />";

XmlNode xmlNode = SharePointListWebService.GetListItems(
_listServiceConfigurationSettings.ListName,
                                string.Empty,
                                query,
                                viewFields,
                                null,
                                queryOptions,
                                null);

According to fiddler, this results in the following soap envelope being posted to the list service:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <soap:Body>
    <GetListItems xmlns="http://schemas.microsoft.com/sharepoint/soap/">    
      <listName>Shared Documents</listName>
      <viewName />
      <query>
        <Query xmlns="">
          <Where>
            <And>
              <Contains>
                <FieldRef Name="FileLeafRef" />
                <Value Type="Text">.xls</Value>
              </Contains>
              <Geq>
                <FieldRef Name="Modified"
                IncludeTimeValue="True" />
                <Value Type="DateTime">2010-05-10T11:53:32Z</Value>
              </Geq>
            </And>
          </Where>
          <OrderBy>
            <FieldRef Name="FileDirRef" />
          </OrderBy>
        </Query>
      </query>
      <viewFields>
        <ViewFields xmlns="">
          <FieldRef Name="LinkFilename" />
          <FieldRef Name="FileDirRef" />

        </QueryOptions>
      </queryOptions>
    </GetListItems>
  </soap:Body>
</soap:Envelope>

and the following soap response being returned from the service:

Notice the z:row element has more fields included than I specified in my ViewFields criteria. I also set IncludeMandatoryColumns to false in my query options. Did I do something wrong or do I not understand how ViewFields really works as I thought it would limit the fields i.e. z:row attributes returned by the SharePoint list service.

I’ve been struggling with this issue, too. Tonight I found a solution that seems to work for me…hopefully it’s helpful for others, as well.

The structure of your viewFields node is fine…

   <viewFields>
    <ViewFields xmlns="">
      <FieldRef Name="LinkFilename" />
      <FieldRef Name="FileDirRef" />
      <FieldRef Name="FileLeafRef" />
    </ViewFields>
  </viewFields>

The problem is likely your field names. Apparently you have to use the internal names rather than the display names. One quick & easy way to determine the internal names is to go to the List Settings page for your list and hover over each column in the list. The browser’s status bar will show a URL similar to this..

http://YOUR_SITE/_layouts/FldEdit.aspx?List=%7B12345678%2D1234%2D1234%2D1234%2D123456789012%7D&Field=INTERNAL_FIELD_NAME

Use the internal field name shown there for each of the fields you want to return from the GetListItems() service. For example,

<FieldRef Name="LinkFilename" />

….might need to be written as…

<FieldRef Name="Link_x0020_Filename" />

At least that’s what it took to solve the problem for me. Hope that helps!
