Introduction Sharepoint exposes some really useful webservices. One among the most useful is the List Webservices.
We can take the webreference from the following location
http://mossserver/_vti_bin/lists.asmx
Once we have added the webservice, we can use following generic method to call webservice. {codecitation class="brush: csharp; gutter: true;" width="700px"}
XmlNode CallWebService(bool isRecursive, ListsService listService,
string listName, string queryObj, string viewID, string viewFieldsInnerXml)
{
try
{
NetworkCredential credential = new NetworkCredential();
credential.UserName = "UserName";
credential.Password = "Password";
credential.Domain = "Domain";
listService.Credentials = credential;
// Instantiate an XmlDocument object
System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
string viewName = string.Empty;
if (string.Empty != viewID)
{
viewName = viewID;
}
string rowLimit = "150";
System.Xml.XmlElement query = xmlDoc.CreateElement("Query");
System.Xml.XmlElement viewFields = xmlDoc.CreateElement("ViewFields");
System.Xml.XmlElement queryOptions = xmlDoc.CreateElement("QueryOptions");
if (isRecursive)
queryOptions.InnerXml = "";
else
queryOptions.InnerXml = "";
if (string.Empty == queryObj)
{
query.InnerXml = "" +
"0";
}
else
{
query.InnerXml = queryObj;
}
// Assign View fields
if (string.Empty != viewFieldsInnerXml)
{
viewFields.InnerXml = viewFieldsInnerXml;
}
else
{
viewFields.InnerXml = "";
}
System.Xml.XmlNode nodeListItems =
listService.GetListItems(listName, viewName, query,
viewFields, rowLimit, queryOptions, null);
return nodeListItems;
}
catch (Exception ex)
{
throw ex;
}
}
{/codecitation} You can use this generic method for getting the list items.
Pass true to “IsRecursive” if you want to get items inside folder.
Example:
{codecitation class="brush: csharp; gutter: true;" width="700px"}
string fields = "
";
XmlNode nodeListItems = CallWebService(true, l, "Answer Choices",
string.Empty, string.Empty, fields);
foreach (System.Xml.XmlNode listItem in nodeListItems)
{
if (listItem.ChildNodes.Count > 0)
{
foreach (XmlNode node in listItem.ChildNodes)
{
string choice = node.Attributes["ows_Title"]
.Value;
}
}
}
{/codecitation} That's all, try in your development. Thank you Amal |
