Visualizar PDF no site SharePoint

Este conceito é muito bacana e pra quem quer facilitar para olhar seu arquivo pdf no prórpio site pdf segue ai tutorial muito bom que encontrei.

O conceito é similar ao Page Viewer(PVWP) Esta WebPart cria um IFRAME object e seta atributo para a pagina.



Através de um DropDown você seleciona o nome do documento.



Crie uma biblioteca de documentos para inserir seus documentos em pdf
Aqui está sendo apontada para a biblioteca de documentos




Segue o código para criar está WebPart
Esta WebPart foi desenvolvida no Visual Studio 2008

[Personalizable(PersonalizationScope.Shared),
WebBrowsable(true),
WebDisplayName("Document Library"),
WebDescription("Enter in the Url to the document library")]
public string LibraryUrl
{
  get { return _docLib; }
  set { _docLib = value; }
}

Aqui o codigo método CreateChildControl para esta webpart

protected override void CreateChildControls()
{
  base.CreateChildControls();

  iframeObjectID = "iframe_" + guid;

  string siteUrl;
  string webUrl = string.Empty;
  string fileContents = string.Empty;

  //Define our DropDown List
  dl = new DropDownList();
  dl.Attributes.Add("onchange", "LoadFile_" + guid + "();");
  dl.Items.Add("Select a document");

  SortedDictionary <string,string> files;

  try
  {
      //Is our document library path set?
      if (this._docLib != null)
      {
          //decode any %20 spaces in URL
          siteUrl = this._docLib.Replace("%20", " ");

          //Open site collection
          using (SPSite site = new SPSite(siteUrl))
          {
              //this block of code allows us to extract the relative Url of a subweb
              if (site.Url.Length + 1 <= siteUrl.Length)                {                    webUrl = siteUrl.Remove(0, site.Url.Length + 1);                }                 //open web
              using (SPWeb web = site.OpenWeb(webUrl))
              {
                  //get handle to our document library
                  SPDocumentLibrary library = (SPDocumentLibrary)web.GetList(_docLib);

                  //create a generic sorted dictionary to store the files
                  files = new SortedDictionary<string, string>();

                  //loop through each file in root folder and add to sorted list
                  foreach (SPFile file in library.RootFolder.Files)
                  {
                      files.Add(file.Name, web.Url + "/" + file.Url);
                  }

                  //add each sorted file name to our drop down list
                  foreach (KeyValuePair<string, string> key in files)
                  {
                      ListItem item = new ListItem(key.Key, key.Value);
                      dl.Items.Add(item);
                  }
              }
          }
          //Add drop down list and break tag to web part
          this.Controls.Add(dl);
          this.Controls.Add(new LiteralControl("
"));

          //Define a literal control to hold generated HTML  (This will become our iframe)
          iframe = new LiteralControl();
          //Uniquely stamp this IFRAME
          string frameGuid = new Guid().ToString();
          iframe.Text = "";
          this.Controls.Add(iframe);
      }
      else
      {
          //Set literal text to configure this web part
          LiteralControl html = new LiteralControl("Click  + this.ID + "')\">open tool pane to set path to Document Library");
          this.Controls.Add(html);
      }
  }
  catch (Exception ex)
  {
      //Display any error that comes up
      this.Controls.Clear();
      this.Controls.Add (new LiteralControl ("An error occurred: " + ex.Message.ToString()));
  }


}

Agora o JScript para DropDown

crie antes
maiores detalhes veja aqui

protected override void OnPreRender(EventArgs e)
{
   base.OnPreRender(e);

   if (!Page.ClientScript.IsClientScriptBlockRegistered ("script_" + guid))
   {
       //dynamically generate our JavaScript
       string script = @"function LoadFile_" + guid + @" () {
var iframeobj = document.getElementById ('" + iframeObjectID + @"');
var selectobj = document.getElementById ('" + dl.ClientID + @"');
if (selectobj.value.toLowerCase().indexOf ('http') != -1)
{
iframeobj.src = selectobj.value;
iframeobj.style.visibility = 'visible';
}
else
{
iframeobj.src = '';
iframeobj.style.visibility = 'hidden';
}
}
";
       //register our client side script that is an embedded resource
       Page.ClientScript.RegisterClientScriptBlock (typeof (Page),"script_" + guid, script,true);
   }
}


Agora é só fazer o deploy da solução

stsadm –o addsolution –filename <full path to WSP file>
stsadm –o deploysolution –filename  –url <path to Web application>
stsadm –o activatefeature –name FileViewer –url <path to site collection where you want to use this>
