multiple content type in one library

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :C#
I created a content type based on the Document content type.  Call this ContentType A.  I associated a custom document template with it.  Then I created another content type.  Since I wanted it to have the exact same columns as ContentType A, I based it on that, but gave it its own document template.  I  needed to make a change to ContentTypeA.  I then noticed that when I select the template (from the library New menu) for contentType B, that it opens the template from contenttype A.  Should I not have based contenttype B from contenttype A?  Or would it have been best to create it based on Document and just recreate all the same columns?
There are no mistakes; every result tells you something of value about what you're are trying to accomplish.

can you upload multiple documents (to a doc library) and set content type and meta data at same time

can you do this?  it doesn't seem like the dialogs support this functionality.  As an alternative i tried doing it in a grid type view after the fact but i couldn't get the grid view to show the content type, even worse, the grid view would let me add meta data to content types that didn't even have that column as long as it was in the view!!

External Data Fields in a Word Template saved as a content type in a document library with multiple


I have created a Word Template for a Document Library that has an External Data Column in it of Client Name which also adds Client Address1, Client Address2, Client City, Client State, & Client Zip.  Now this works fine for a Document library with that template as the Template.dotx file. 

I want to be able to make a bunch of Templates and have them all as Content Types in one Library.  When I do this I cannot get the External Data Quick Parts to work.

Anyone have any ideas?

URGENT: Document Library Content Type not inheriting some fields from parent Site Content Type


I have a situation that has foxed me!! I have a site level content type that has 8 fields... I use this to create more content types at the site level and use these in multiple Document Libraries (I have 40 doc libs).  This works fine for 38 of the libraries.  But for 2 of them... 2 of the columns are not showing up on the document libraries.  These are user lookups fields.  I am not sure why it's not working in these libraries only!  When I use the same content type in another library... the inheritance does not break for these fields!

Anyone please provide some guidance on this?  I am using WSS 3.0 and SPD to do workflows.

On another note... the content type has a template (in excel) attached to it.  When I create the content manually using the content type from the New menu option, the template is used... however, when I try to add it using an SPD workflow, it creates a blank template... the content type template is not being used.

Please help... I am in a fix and need to release this application today!!!

Change the content type for multiple list items


I have a document library which is configured to manage content types.  Users will be expected to upload multiple documents into the library.  Then they will be expected to choose the content type of the file and fill in the required metadata.  The only difference in these content types is the template which will be used to create new files of the specific content type so the columns are identical for each content type.

I have created a public view with inline editing enabled but Content Type is not an editable field.

The problem I have is that when I enable Inline editing, the users don't have an opportunity to select the content type, even though the files have just been uploaded and have not been checked in.

My question is this; how can users change the content type of multiple items without having to go through the complete New Item form? 

With literally thousaands of documents to be imported, having the users fill out a separate form for each document when many will have the same column values is a show stopper for our rollout.  It will take too much time.  The project will be a failure. 

I've also tried to create a datagrid view but the same problem exists.  Content type is not an editable column value.

Thanks for helping.


Multiple Content Types in a single list - how to edit fields outside a content type

I have a single list and created two content types on the list in order to reduce the amount of visible fields a user sees when entering a form.  Once the form is filled out by one group with the limited data, an alert is sent to another team that adds to the list item using the larger set of fields defined by the second content type.  Unfortunately it seems that the edit burron remembers ihe initial content type that the entry was created with.  Is there another url to access the edit button for the same entry using the alternate content typr?

Adding New Custom Folder Content Type doesn't show up on the Document Library New Menu


I been trying to add new custom folder content type to the document library programatically in my sandbox environment and it does show up on the document library. But, when I move same code to the almost similar configured SP2010 environment, adding new folder content type to the document library doesn't show up on the document library's new menu.

Here is the code? Since this code works fine in my sandbox environment, is there any other settings I should check on the server environment which would cause hiding content type on new menu of document library.

  class Program
    static void Main(string[] args)
      SPSite spSite = new SPSite("http://sp2010vm");
      foreach (SPWeb spWeb in spSite.AllWebs)
        spWeb.AllowUnsafeUpdates = true;

        //For each site, cycle through lists
        bool isDocLibraryExists = false;
	      foreach(SPList spList in spWeb.Lists)
          if(spList.Title == "Classified Documents")
             isDocLibraryExists = true; 
        if(isDocLibraryExists == true)
          //Create new doc library
          SPList splist = spWeb.Lists["Classified Documents"];

          //Create Content Type
          SPContentType documentContentType = spWeb.AvailableContentTypes["Classified Documents Folder"

Custom document library list template issues with custom content type


Either I don't know what SharePoint is doing or I don't know what I'm doing (or both, which is more likely).

I'm attempting to create a Custom Document Library template with a custom content type association (Custom Document), all using a feature. When I create
a document library based on the installed template, the content type association is there. However, when I click on New Custom Document, the template.dotx does not reflect the Custom Document content type association. The Word document information panel does not show any Custom Document content type properties (like Title and Comments).

Here are the steps I've taken:

1. Create the feature.xml with element manifests of contentType.xml and CustomDocumentLibrary.xml
2. Create the contentType.xml (Custom Document) with an additional field reference for Comments
3. Create the CustomDocumentLibrary.xml for the list template
4. Create a Custom Document Library subfolder that contains the same files that are in the 12\TEMPLATE\FEATURES\DocumentLibrary\doclib folder.
5. Edit the schema.xml to use the new content type and field reference
6. Deploy and activate the feature
7. Create a new "Custom Document Library"
8. Go to Custom Document Library Settings and verify the Custom Document content type is being used
9. Click on New Custom D

PDF form as Content Type for SharePoint Document Library


Is there any way to use PDF form (.pdf)  template as Content type for document library??

I have a pdf form template and i want to make a content type of it, so i can use it for my Document Library. I defined a new content type of it with following settings:

Select Parent Content From dropdown: Special Content Types,
    Parent Content Type Dropdown: Unknown Document Type

Under Advance Settings i uploaded the pdf form template to server. Under Document Library Settings I add this content type to it, now when i click NEW button it gives me an error message saying:

"The Document couldn't be created. The required application may not be installed properly, or the template for this document library can't be opened"

Seems like SharePoint doesn't integrate with or support Adobe Reader to open PDF form as Content Type or I am missing something there (for example: dll ).

I would really appreciate if you help me on this. Thanks


Document Library/Content Type Planning


Im in the process of moving a network drives content to a new document library.

The network contains all our IT Sarbanes Oxley documentation/checks


What im struggling with is how to plan the document library.

Should I create a team site for this network drive and have multiple document libraries?
Or should I create just one document library?

What im struggling with is how to plan andocument library.


for example,
currently every morning a member of staff completes a check of server backups.
They modify an Excel spreadsheet which contains a row for each site/server and a column for each day.
This Document is located at O:\IT Procedures Policies & Controls\Controls\KC202 - Monitor Backups
Every month a new Spreadsheet is started which is based on a template.

My first idea was to create a content type for this check called 'KC202' as a template can be assigned then each month the user just needs to hit the dropdown button and then 'new KC202'.
the problem with this is we have 37 folders within 'Controls' ranging from KC000 to KC507 all of which will need template documents (each being Unique)

Then I thought the best idea would be to have a content type for 'Controls' with metadata for the 'KC' number. Whenever a new document is created the user can

error with "Create new content" type Translation Management Library


I added the Translation Management feature today, using the following command line:

stsadm -o activatefeature -name TransMgmtlib -url http://mysite

everything seemed to work fine, as no error occurred at this stage, and when I go to my top level site settings, click on "Site libraries and lists", then "create new content" I now see "Translation Management" as an option.

I select this type, click Create, complete the first part of the 'wizard' (Name and Description, etc.), then I'm on step 2 and this is where the error occurs. 

  1. The Workflow select box is disabled, and from the articles I've read this should be usable.
  2. More critically, when I complete this form and click Next, I get a server error:

    Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. 

I've googled around, and tried updating various items in my web.config and machine.config, but I cannot find the solution. A lot o

RPC and C++: Build a Template Library for Distributed Objects Containing Multiple Interfaces


Building a C++ template library for developing distributed object-oriented applications using Remote Procedure Calls (RPC) allows the programmer to design RPC applications that are composed of components that implement multiple interfaces. This article demonstrates the use of techniques such as assembly-level thunks to build machine code on the fly, and C++ features such as templates, conversion operators, virtual destructors and virtual function tables. Along the way, familiar C++ interfaces and classes are transformed into a distributed application. The benefits of using distributed objects rather than raw remote procedures, which include writing fewer lines of code, is explained.

WSS 3.0 Content Type with Office 2007


We're currently encoutering an issue on our production servers with Office 2007 documents. In essence, the Content Type for all docx, xslx, and pptx documents cannot be changed away from the site default on all newly created sites.

I've even done some step by step debugging on an SPItem insert and I can set the content type to a custom type, but it reverts back to the site's default Content Type on Update(). Other file types - .doc, .xls, .tif, .txt, and .jpg - have all been tested, and all work as expected (the Content Type changes correctly).

Thanks in advance!


WSS 3.0 Content Type - Lost data for Titles


We are running WSS 3.0 SP2 on server 2003.  Recently, we lost the "Titles" for all content types for documents.  Our system Content Type for Document is set up to require this field to be completed on all documents that is uploaded.  Our system would automatically enter in by default the name of the document in the "Title" field it no longer does this for the user.  The user must now enter in manually the "Title".  How do I get it to enter in the "Title" using the document file name automatically?

Below is the way the setting page for Site Content Type: Document looks like.  (I tried to recreate it since I could place a screen shot in the box)

Site Content Type Information
Name:  Document
Descriptiong:  Create a new document.
Parent:  Item

Issue with List Definition of same base content type and deployed via same feature


I am trying to deploy two custom list definitions using only one single feature.  Below are the details of my issue.

  • Two custom list definitions
  • Each custom list definition has its own custom content type
  • Each custom content type inherits from the base content type Picture (Type = 109)
  • The custom list definitions are grouped together under one single feature
  • The custom content types are grouped together under a seperate single feature

When I deploy my solution in this configuration, the second list definition gets the first custom content type applied to it and the list schema from the first list definition is also applied to the second list definition.

What makes this more interesting, when I seperate both of the list definitions under two seperate features it all works fine.  Custom content types and list schemas get applied correctly.

Can anyone tell me why I can not deploy both list definitions under one single feature?

If you need me to post any of the origional code or XML to this post please let me know.
