Re: Getting Webservice UpdateListItem to return the newly created list item ID from a Sharepoint List

Basically you need to look in the result XML from your UpdateListItems call to find the value of the ows_ID node and use that for the listItemID value in the AddAttachment call:

My main function that is calling the sharepointServices:

//Add new Row to SharepointList

result = listService.UpdateListItems(strListID, batchElement);

//Add Attachment to new row

KeyValuePair<int, string> listItemId;

listItemId = CheckListUpdateResults(result);

listService.AddAttachment(strListID, listItemId.Key.ToString(), "Test", bytes);

A useful function that will return the new rowID from your UpdateListItems call (found here):

//Returns ID of new List Row

private static KeyValuePair<int, string> CheckListUpdateResults(XmlNode resultsNode)

{

if (resultsNode == null) return new KeyValuePair<int, string>(0, "Null results node supplied");

XmlNamespaceManager ns = new XmlNamespaceManager(resultsNode.OwnerDocument.NameTable);

ns.AddNamespace("sp", resultsNode.NamespaceURI);

var errorCode = resultsNode.SelectSingleNode("//sp:ErrorCode", ns).InnerText;

if (errorCode == "0x00000000")

{

// grab the list item ID

var owsID = resultsNode.SelectSingleNode("//@ows_ID").Value;return new KeyValuePair<int, string>(Convert.ToInt32(owsID), null);

}

var errorText = resultsNode.SelectSingleNode("//sp:ErrorText", ns).InnerText;

var result = new KeyValuePair<int, string>(0, string.Format("Error {0}, {1}",

errorCode ?? "n/a",

errorText ?? "n/a"));

return result;

}

Here is a solution to this problem. public static int NextListItemID(SPSite oSite, Guid listId) { int listItemId = -1; Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(delegate() { if (oSite.WebApplication.ContentDatabases.Count > 0) { //Get the connection string for the sharepoint database string connString = oSite.WebApplication.ContentDatabases[0].DatabaseConnectionString; //Establish a connection SqlConnection con = new SqlConnection(connString); try { con.Open(); http://www.mindfiresolutions.com/How-to-programatically-get-the-next-item-ID-for-a-SharePoint-list--884.php

Thanks for the suggestion but I prefer a non 3rd party solution to what appears to be possible without one.

Hi - you might want to try qRules. It has a SubmitToSharePointList command which uses the UpdateListItems web service to submit and/or update list items and return the ID. Works great for repeating data too!

For more info, please check this blog post: http://www.infopathdev.com/blogs/hilary/archive/2009/11/16/submit-items-to-a-sharepoint-list-with-qrules-v2-0.aspx

You can try out qRules for free by downloading the tool here.

Cheers!

Getting Webservice UpdateListItem to return the newly created list item ID from a Sharepoint List

I used the Data Connections Wizard to create a Webservice to submit from InfoPath to a Sharepoint list using the UpdateListItem service. I'm using custom_code, triggered from a submit form button, to accomplish this and execute the Webservice. What I can't figure out is how to programmatically get at the results of that service in order to extract some crucial information I need. I want to get a hold of the new ID that was assigned for my new list item. I want to be able to use this ID in order to trigger a secondary Webservice call (addAttachment) to add attachments to the newly created list item.

Some more details:

In my submit form programming, I am creating a WebServiceConnection object that ties back to the Data Connection I created with the wizard in Infopath:

WebServiceConnection wsSubmit = (WebServiceConnection)this.DataConnections["Web Service Submit"];

I perform a series of steps to create CAML code and then finish things up by executing the WebServiceConnection:

wsSubmit.Execute();

I want to be able to get the new ID that was created for my list item, assign it to field defined in Main which is referenced in a second WebServiceConnection that calls the AddAttachment service which utilizes the listitemID.

In addition, I just want to be able to access any return results from the web service (e.g. error codes).

Any suggestions on this?
