Make MetaData READ ONLY

Posted By:      Posted Date: August 26, 2010    Points: 0   Category :SharePoint


I want to make the metadata of a document set to read only. The business idea is that when the document is created the first time, it is modifyable. However, few years down the line when the document comes up for revision, we want the metadata columns to be set to read only.

make columns read only in a list

Hi, I am using SP 2010 and needed help in customizing an exisiting list. I need to make 3 columns of the list editable to 3 users only and the rest of the users have a READ-ONLY option. How can this be done?

ReadOnlyEnforced not working? How to make a field always read only?



I want to create a custom content type (a feature) and includes a field that will be always displayed to user but always in ReadOnly mode.

I'm creating items from a worklfow and what to unable user to modify some values....

I'd make some reasearch and found the "ReadOnlyEnforced " attribute.



This is the attribute definition: Optional Boolean . TRUE to specify that the user cannot change the field by any means and that it can only be changed by the system.


This is what I do and redo again to be sure... but it's not working! I'm starting to be a little bit discourage about that, because I can't allow user to change value of this fields...

It's a little bit frustrating, because the definition gave in documentation is right what I need lol But it's not working...

Anyone had this kind of problem? Any solution?

How read flowdocument xaml to make available in vb code


I'm very very new to WPF and not particularly experienced in VB.Net (mostly a VBA man) so forgive me if this comes across as completely idiotic, cause it more than likely is :-( .....

The problem I have is that I want the user to have the ability to insert buttons into a richtextbox and be able to put essentially as many buttons as they like in and amongst some text.... simple enough....

Problem is I'm finding this impossible with my limitted knowledge of anything WPF related.....

I can use the following code to allow the user to double click in the rtb at a certain point and the code will go off and create a flowdocument (in vb) with an inline container with a button in it and then merge the text from the rtb with the flowdocument.... 



 Dim WithEvents aButton As TextBox = New TextBox (class level variable)

Dim aFlowDocument As FlowDocument = New FlowDocument

Dim bparagraph As Paragraph = New Paragraph

        bparagraph.Inlines.Add(New InlineUIContainer(aButton))




How to make document libraries read-only. How to block users to not able to upload or create new doc



We are planning to perform a backward migration from MOSS 2007 to WSS3.0 on one of our sharepoint farms. For this migration we like to disable the users to modify the existing doc-libraries or invidual documents. We also want to restrict the users from creating new document-libraries or upload new documents onto sharepoint sites.

Can somebody tell if there is a way to accomplish this either by using GUI or SharePoint API ?

Thanks ahead.

Beginner: this doesn't make sense to me


Do you need and "empty" script tag in the head to run scripts that are in the body?  Also, can you run JQuery scripts if they're in the <head> tag?  The first sample only works if the JQuery script is in the form (and body) tag, not in the head - even if I add $(document).ready(function() { });

This works

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
<script type="text/javascript">
<form id="form1" runat="server">
<a href="">Here is a link</a>
<script type="text/javascript">
$('a').click(function () {
alert("you clicked me!");


This doesn't work.  Notice I removed the second <script> tag from the head

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="serve

Scripts not read when in head tag


I just upgraded to VS2010 if that matters.  I'm learning JQuery and noticed that scripts don't work if they're in the head tag.  Also, I need the script tag with type="text/javascript" in the head (with nothing else) in order for the JQuery scripts in the body to work.

Very bizzare, any suggestions?

With a separate script tag in the <body> with my JQuery script, this works

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
<script type="text/javascript">

This doesn't:

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />

Need Syntax To Make Results of LINQ Union Return Non-Generic Type



I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont

Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

What are other requirements  ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.

How to read Excel table?
