UploadCtl Control

SharePoint 2003

An UploadCtl control allows multiple documents to be uploaded from an external application to a document library on a site in Microsoft Windows SharePoint Services. When a user clicks Upload Multiple Files... on Upload.aspx, the page for uploading documents, an <OBJECT> tag for the control is created on the page as follows:

<OBJECT id=idUploadCtl name=idUploadCtl
  CLASSID=CLSID:07B06095-5687-4d13-9E32-12B4259C9813
  WIDTH='100%' HEIGHT='350px'></OBJECT>

Note  The CLSID used in this tag is the GUID that uniquely identifies the ActiveX control that is installed with Microsoft Office 2003. To implement a custom control for uploading documents, specify a different GUID.

When Office 2003 is installed on the client computer, this control is defined in the STSUPLD.DLL file, a dynamic-link library (DLL) that is installed on the client during Office 2003 setup in the Local_Drive:\Program Files\Microsoft Office\OFFICE11 directory.

MultipleUpload Method

expression An expression that returns an UploadCtl object.
newVal A string of the form #aabbcc, where the characters are hexadecimal values in the order BGR and represent the color.

Example

The following example steps through the process of adding an UploadCtl control to an .aspx page for uploading multiple documents to the Shared Documents folder of a specified site. The example adds a hidden UploadCtl control within the page that is displayed when a link is clicked.

The .aspx file, in this example WebForm1.aspx, must be located in the Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\60\TEMPLATE\LAYOUTS directory, and is opened through the URL http://Server_Name/_layouts/WebForm1.aspx.

  • Add a page directive that registers the Microsoft.SharePoint.WebControls namespace:
    <%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
    Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
    PublicKeyToken=71e9bce111e9429c" %>

    Note  You can obtain the PublicKeyToken value for the current Microsoft Windows SharePoint Services deployment from the default.aspx file in the Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\60\TEMPLATE\LCID(1033 in English)\STS folder, or from information provided for the Microsoft.SharePoint assembly at Local_Drive:\WINDOWS|WINNT\assembly in Windows Explorer.

  • Add a LINK element in the HEAD section to apply Windows SharePoint Services styles that are defined in ows.css:
    <LINK REL="stylesheet" TYPE="text/css" HREF="/_layouts/1033/styles/ows.css">
  • Add a script block to the HEAD that includes 2 methods. One method sets the background color for the tree view and displays the UploadCtl on the page. The other method uploads documents that are selected in the control.
    <SCRIPT LANGUAGE="javascript">
    function MultipleUploadView()
    {
        document.all.idUploadCtl.SetTreeViewColor("#FF0000");
        document.all("idMultipleView").style.display="inline";
    }
    
    function DocumentUpload()
    {
        document.all.idUploadCtl.MultipleUpload();
    }
    </SCRIPT>
  • Add a form within the BODY section of the .aspx page:
    <FORM NAME="frmUpload" METHOD="post"
       ACTION="WebForm1.aspx?RootFolder=&amp;Source=http%3A%2F%2FServer_Name%2FShared%2520Documents%2FForms%2FAllItems%2Easpx">
  • In order to upload documents and thereby modify data within a SharePoint site, a FormDigest server control must be included in the form:
    <SharePoint:FormDigest runat="server" />
  • Include INPUT elements that specify the required parameters of the post:
    <INPUT TYPE="hidden" NAME="Cmd" VALUE="Save">
    <INPUT TYPE="hidden" NAME="NextUsing"
       VALUE="http://Server_Name/Shared%20Documents/Forms/AllItems.aspx">
    <INPUT TYPE="hidden" VALUE="New">
    <INPUT TYPE="hidden" NAME="putopts" VALUE="true">
    <INPUT TYPE="hidden" NAME="destination"
       VALUE="http://Server_Name/Shared Documents">
    <INPUT TYPE="hidden" NAME="Confirmation-URL"
       VALUE="http://Server_Name/Shared%20Documents/Forms/AllItems.aspx">
    <INPUT TYPE="hidden" NAME="PostURL"
       VALUE="http%3a%2f%2fServer_Name/_vti_bin/shtml.dll/_layouts%2fWebForm1%2easpx" />
    <INPUT TYPE="hidden" NAME="VTI-GROUP" VALUE="0">
  • To complete the form, add a link for calling the MultipleUploadView method and displaying the contents of a DIV section, which includes the OBJECT tag that creates the control on the page:
    <P CLASS="ms-toolbar">
       <A HREF="javascript:MultipleUploadView()"
          TARGET="_self">Upload Multiple Files</A>
    </P>
    <DIV ID=idMultipleView style='display:none'>
    <P CLASS="ms-toolbar">
       <A HREF="javascript:DocumentUpload()"
          TARGET="_self">Save and Close</A>
    </P>
    <OBJECT id=idUploadCtl name=idUploadCtl
    	  CLASSID=CLSID:07B06095-5687-4d13-9E32-12B4259C9813
    	  WIDTH='100%' HEIGHT='350px'>
    </OBJECT>
    </DIV>
    </FORM>
