Aggiungi web parte in modo che possiamo recuperarlo in seguito tramite CSOM?

Question

Come aggiungere una parte web a pagina in modo tale che in seguito possa trovarlo (usando CSOM) - possiamo in qualche modo memorizzare le informazioni sull'identificatore per il web part?Dire che l'utente potrebbe modificare il titolo e la descrizione (quindi non possono essere utilizzati come identificatori).

o dobbiamo usare (ASMX) Servizi Web ..

Modifica

appare ASMX è necessario. Vadim propone una soluzione JavaScript qui sotto. Qui anche un semplice codice server-side (client utilizza _vti_bin / webpartpages.asmx)

XElement resultElement = client.GetWebPartProperties2("/SitePages/DevHome.aspx", Storage.Shared, SPWebServiceBehavior.Version3);

var webParts = new List<Dictionary<string,string>>();
foreach (XNode webPartNode in resultElement.Nodes())
{
  var properties = new Dictionary<string,string>();
  XElement element = webPartNode as XElement;
  foreach (XNode propertyNode in element.Nodes())
  {
    XElement propertyElement = propertyNode as XElement;
    if (propertyElement != null)
    {
      properties.Add(propertyElement.Name.LocalName, propertyElement.Value);
    }
  }
  webParts.Add(properties);
}

.

Edit2 Come punti Ali di seguito abbiamo potuto utilizzare la web part GUID come identificatore: lo capiremmo durante la creazione della web part, memorizzalo in una posizione esterna e usarlo in seguito.Tuttavia, in questo caso non possiamo usare / archiviare questo identificatore ma è necessario fornire il nostro.Quindi l'unica possibilità rimanente sembra essere asmx.

WebPartPagesWebService exposes GetWebPartProperties2 Method that could be used to retrieve information about web parts (eg, WebPartID) on page

For example, the code below demonstrates how to get Web Parts Ids:

function getWebPartProperties(pageUrl,completeFn,errorFn)
{
    var soapEnv =
        '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">  \
            <soap:Body>  \
                <GetWebPartProperties2 xmlns="http://microsoft.com/sharepoint/webpartpages">  \
                    <pageUrl>' + pageUrl + '</pageUrl>   \
                    <storage>Shared</storage>   \
                    <behavior>Version3</behavior>   \
                </GetWebPartProperties2>  \
            </soap:Body>   \
        </soap:Envelope>';

    $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + "/_vti_bin/WebPartPages.asmx",
        type: "POST",
        dataType: "xml",
        data: soapEnv,
        complete: completeFn,
        error: errorFn,
        contentType: "text/xml; charset=\"utf-8\""
    });
}                


$(function() {
    getWebPartProperties('/SitePages/DevHome.aspx',
        function(xhr,textStatus){
            $(xhr.responseXML).find("WebPart").each(function() {
                var wpId = $(this).attr("ID");

                //Manipulate web part by Id via CSOM here... 

            });

        },
        function(xhr,textStatus,errorThrown){
            console.log(errorThrown);
        });
});

Answer 2

Using the WebPartManager one could retrieve all web parts in a page, see example by http://blogs.technet.com/b/speschka/archive/2009/11/01/using-the-sharepoint-2010-client-object-model-part-6.aspx

In terms of web service access, there is of course a SOAP web service the Web Part pages web service (http://msdn.microsoft.com/en-us/library/ms774569(v=office.12).aspx) which allows manipulating web parts in a page.

Each web part has an Unique Identifier automatically added by SharePoint anyway, so you don't need to add another one. Your best choice here is still the WebPartManager (Shared or Personal).

Answer 3

//get the connection
ClientContext ctx = new ClientContext("http://foo");


//get the home page
File home = ctx.Web.GetFileByServerRelativeUrl("/SitePages/home.aspx");


//get the web part manager
LimitedWebPartManager wpm = home.GetLimitedWebPartManager(PersonalizationScope.Shared);

//load the web part definitions
ctx.Load(wpm.WebParts);
ctx.ExecuteQuery();

//get the web part definition
WebPartDefinition wpd = wpm.WebParts.GetById(MyWebPartId);

//set the title
wpd.WebPart.Title = "My Web Part Title";

the above does what your asking for as c. marius has pointed out, as for a unique ID, its already set. wpd.WebPart.ID will show the id.... if you return that value within a lable or textbox than youll see the unique ID that is auto generated! Title and description are not unique!

http://msdn.microsoft.com/EN-US/library/microsoft.sharepoint.client.webparts.webpartdefinition_members.aspx

if you want to search by title:

//get the connection
ClientContext ctx = new ClientContext("http://foo");


//get the home page
File home = ctx.Web.GetFileByServerRelativeUrl("/SitePages/home.aspx");


//get the web part manager
LimitedWebPartManager wpm = home.GetLimitedWebPartManager(PersonalizationScope.Shared);

//load the web part definitions
ctx.Load(wpm.WebParts);
ctx.ExecuteQuery();

foreach ( WebPart wp in wpm.WebParts)
{
       //get the web part definition
       WebPartDefinition wpd = wp;

      //get the title
      string title = wpd.WebPart.Title;

      //get the ID
      string id = wpd.WebPart.ID;

      //get a specific webpart with a specific title
      if (wpd.WebPart.Title == "HOME")
      {
         //return ID
         string id = wpd.WebPart.ID;
      }

}
