Customizing External List Fields

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :SharePoint
I have two SharePoint features:  a BDC model and an external list definition.  Everything deploys and works as expected.  However, I would like to customize the fields in the list.  For example, I want a date only field, multi-line text field and a choice field instead of a date and time field and two single-line text fields.  I am using a custom schema.xml in the list definition, but the fields section is ignored.  I have also tried to alter the fields through the object model with no luck.  Currently, the solution is easy to deploy.  So I'd like to avoid additional steps in SharePoint Designer.  Although I don't see any options for customizing field types anyway (outside of manually editing the forms).  I'm not using the Enterprise edition, so Infopath is not an option.  In the BDC model in Visual Studio I set a few fields to Nullable DateTime.  The Central Admin shows it as DateTime and required though.  Surely there is a way to change that behavior.  Any suggestions?

Customizing the External list



I have connected a BCS to a external list. I am able to do all the operations like create new item, delete and update.

Most of the columns in the external list are textbox now. I would like to customize the external list to have dropdown box, textbox, checkbox depending on the business requirements.

How to customize the external list to have different columns attached to it.

Thank you

calculate fields in a list

I have a field( choice ) that has three choices (Low, Medium and High ). If I choose Low, I need to add 5 days to the current date( excluding weekends ) and place it in the Target date field, the same goes for Medium = 3 days( exclude weekends) , High = 1 day, exclude weekends.



Need to pass parameters from URL to fields in Custom List


I have a complex customized list and I need to pass parameters of two fields so that when the 'Questionnaire' is completed and subsequentially opened after initial submission, it will retrieve the Number and GUID automatically in respective fields. I send an email out with a link to the 'Form' that carries the parameters. I am trying to use the following javaScript but am unsure as to where to place this on the SharePoint page for it to work.



<script type="text/javascript">

function loadFormVars()
getQuerystring('CustodianGUID', 'ctl00_m_g_d08916d8_7224_4665_be72_2de381f45985_ff46_1'); ///replace
customerGUID and form field name
'ctl00_m_g_d08916d8_7224_4665_be72_2de381f45985_FormField11_ctl00_ctl00_TextField'); ///replace customerGUID
and form field name

alert("it works");

function getQuerystring(key, field)
key = key.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regex = new RegExp("[\\?&]"+key+"=([^&#]*)");
var qs = regex.exec(window.location.href);
document.getElementById(field).value = qs[1];


When editing a list item the fields are not blank.


This is a recent issue that I have in which I have a "Issue Tracking" List that maintains the workflow of contract renewals.

When an person goes to edit an existing list entry, the description field (standard) has the original text in the box. Prior to this the original - or any older text from a prior change was listed outside and just below the box - and non editable.

That's not the case anylonger.

Any thoughts?

Updating a List item field value in a SPD Workflow is setting Date fields to null

Hello everybody,I faced a very weird behavior while creating a workflow in SPD against a Document Library.Here is the case:1- Create a document library in sharepoint site.2- Add a custom column of type DATE.3- Upload any document to the library4- Edit the item metadata and set the custom date field to any date you want.5- Now using sharepoint designer, create a very simple Workflow with only one action that updates the current item "Title" field to any value. (Note: In my case I set the workflow to start manually and not automatically)6- Save the workflow and then start it on the uploaded item.7- Now check the value of the date column after the workflow is finished.8- You will see that the Date field is Empty... (very weird)Notes:   1-This behavior will not appear on a standard list. it is only appearing in a Document library.  2- I am using WSS 3.0 SP2 + MOSS 2007 SP2. Also SharePoint designer 2007 SP2Did anyone face this situation and does it have a fix, or am I doing something wrong here... Please help.Regards,Maheed

List view - inline editing with read only fields

I'm new to sharepoint and using SP2010. I would like to use the inline editing feature of list view and at the same time to lock some of the fields. Is there a simpler way to achieve this like adding some field property using SP designer?

External List Profile Pages

I have some external data sources that are related to each other. I created the associations in sharepoint designer, and they all work.  I have a page that has a list of people, that you can search, and when you search for them, it takes you to the profile page that shows the two related lists for that person. This works how I want it. What I want to do has four parts. First, on the initial page that displays my list, I want the primary field (case number) to link to the profile page for that person, instead of the display form. I have tried this with a custom action, but I don't think I did it correctly. Second, on the profile page itself, I have those two related tables that show up. One table is a questionnaire the person filled out, and one is information about interviews they were given.  In the interviews section, I would like the viewer to have an "add interview" button at the bottom, just like any list web part would have. I don't have the option in the web part properties. Finally, on the questionnaire section, I need to alter the view. Right now, there are headings across the top, with the information going left to right. I would like to set it up with a box style, like you can normally do in a list. I would also like to change the field labels from generic field names to more descriptive ones. In addition to that, the questionnaire is entere

External List - Access Selected Items

Hello, The situation;- An external list in SP 2010 from SQL A custom ribbon/button that calls via JS a Dialog box(Application page) and passes the selected items IDs Some code behind to process items after confirmation from user. Question is how to access the selected items in the code behind. As far as I can tell the JS 'getselecteditems' only returns the list ID, which in the case of a standard list is fine, but with an External list returns something like '_B00234' - how do I use this or how to return a more meaningfull ID? (I would rather work in my confort zone VB/C# than JS to process items) casey

How to query for id's of the fields with List Data Retrival Services Query() web service

Since i marked a post as answer in my previous topic, it seems that people dont visit the topic anymore as they see it as "answered" while it actually is only partially answered. So i guess i have to ask again in a different topic.    I need to get data from Sharepoint Server (3.0 i belive) for my Integration Services project. For that i use Sharepoint's webservices. I've read tutorials and downloaded sample programs to talk to WSS web services. I realise i have two ways to get items in a list: Use Query() or GetListItems(). Problem is, GetListItems() has a mandatory "Row limit" field and i might have to import ALOT of fields, so i thought Query() is better for me.  But, when using GetListItems(), the WSS returns the ID of the fields (for example, for a field of type user, something like "395;Ivanov Ivan Ivanovich" is returned) but when using Query() for the same list, WSS returns only the field value ("Ivanov Ivan Ivanovich") without the ID. I need it to return the ID as well. How can i set it up, on my side or server side, so i would receive the ID's, not only the values of the fields that are actually linking to something by ID when i use Query() web service?     

Connecting a Sharepoint Custom list with an external Data-source

Hi I am planning to connect a Sharepoint Custom list with an external Data-source. External DB will be in Access 2007 format. More Information: I need a solution that we can connect our sharepoint list (one-way) to online db in a way that new  information is directly updated in the sharepoint list, whilst other info changed in sharepoint list  is not synced back to original value. Is there a way to solve this? -saumil

Changing the field type in an External List

I have created an External Content Type to a database containing document titles and the URLs to those documents.  I created the External content type operations for read item and read list with the title and url fields (there's a number identifier too). I next created an external list using my external content type. It's great - I can see the information I need from the external Database. BUT... The URL field appears as text and I'd like a clickable Hyperlink.  I'm not sure how I can do this.  Any ideas? Cheers,

Create drop-down filter for External List

I hope this is an easy question. I will have an external list of a bunch of people.  There are several ways I want to display this data: All of them, Only the ones that have a value of 1-4 in the status field, Only the ones that have any other value in the status field, and people that have a value of 1-4 in the status field, but are at a certain location. I want to be able to put a drop-down filter above the list where people can select that. Could someone please point me in the right direction? Time is of the essence.  

Need to link multiple External Content List items to a single document metadata column

I have an external content list - for my purposes, the data isn't any fancier than a list of terms provided by a web service (read only - I don't need update/delete functionality). I want to be able to link any subset of those terms to a single document metadata column (in other words, I need it to work like a normal content list that is defined to allow multiple values in a column) but SharePoint doesn't let me do that on an ECL. I need the content list to be externally driven since more values are going to be added to an outside system over time, but I think it's possible that I may not need a full-fledged ECL list to make this work this way in SharePoint. Just to clarify: I don't need the metadata values in my documents to maintain a PERSISTENT link to the web service (if someone changes an underlying value in the web service DB, it doesn't need to be updated in the document table too). I just want SharePoint to offer up an updated set of source values from the web service if somebody goes in and edits the document metadata. Any ideas for how I can make this work?
