List View Fields/Columns read only

Posted By:      Posted Date: October 21, 2010    Points: 0   Category :SharePoint
 
Hey,

i programmtically add a view to a SP List. Within this view I want to make some columns read only to certain group of users. How should I implement this?

Here is my code for creating an view programmatically:
public partial class _Default : System.Web.UI.Page 

{

    protected void Page_Load(object sender, EventArgs e)

    {

        SPSite mySite = new SPSite("http://spserv");

        //SPWeb myWeb = mySite.OpenWeb("/vst");







        using (SPWeb oWebsite = mySite.AllWebs["website_name"])

        {

            oWebsite.AllowUnsafeUpdates = true;

            SPList oList = oWebsite.Lists["list_name"];

            SPViewCollection collViews = oList.Views;

            string strViewName = "CustomView";

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?

Can Managed Metadata columns be edited in the DataSheet View of a Library or List?

  
Hi, I like to mass set document properties in a library using DataSheet View, the properties are columns based on Managed MetaData values. When I open the doc library in Datasheet view, those columns become read-only. I made sure the library does not require 'Check Out' and also tested it in other views then the AllItems view. Can someone confirm what is the expected functionality and or if there is a bug?

Duplicate Fields during list creation from content types and site columns

  

I am trying to create a List in Sharepoint 2010 using Site Columns and Content Types. It results in creating duplicate fields in the list for the Site Columns used. Here is the details description of what I was doing.

I have created two site columns 

 

<Field Type="Number" DisplayName="Start Coordinate" Required="TRUE" EnforceUniqueValues="FALSE" Indexed="FALSE"
Group="QMS" ID="{A3F2D108-11B5-4B49-9633-338D27227E12}"
Name="StartCoordinate" Overwrite="TRUE" />

<Field Type="Number" DisplayName="End Coordinate" Required="TRUE" EnforceUniqueValues="FALSE" Indexed="FALSE"
Group="QMS" ID="{06B927BB-C354-4A0A-AE88-9C14E55EAB27}"
Name="EndCoordinate" Overwrite="TRUE" />

Then added these to a new content type I

Distinct List View over multiple columns

  

I have a custom list with People, Courses, and Completion Dates. People take multiple courses, and sometimes they also take a course again to refresh. I would like to show the list with all people and all courses, but if a person has taken the same course multiple times, I only want to show the last time the course was taken. In SQL this would be some sort of a DISTINCT query over the combination of PERSON and COURSE. Has anyone done something like this with SP lists (without code ;-) ).

A workaround would be to flag expired courses, once the person has taken the course again. This way you could filter for the not-expired records, but maybe there is a better way. Suggestions?

 

Thx

custom list template columns not in order (not keeping required fields)

  
I have a template (based on a custom content type) that I got working just the way I want it. All the list forms are in the order I want with the fields showing that I want.  I saved this list as a template and create List#2 from that template, but its forms don't show all the required fields (they don't show on the form), and some items are out of order.  Can anyone explain this to me please?  I am working towards a site definition that needs everything just so.
There are no mistakes; every result tells you something of value about what your are trying to accomplish.

Designing a view for Share Point list with vertically repeated columns

  

I want to create a view for a Share Point List, which displays employee name and his/her phone number. I need to design this view in such a way that all items fit on one page and as there are more items they need to be displayed in repeated columns, instead of displaying on next page. Is it possible to achieve this without programming and just using Share Point Designer? I tried the conditional formatting but did not know how to achieve the repeated columns?

Anyone done this functionality or can provide any insight?

 

thanks.


custom field type works in view properties, but not in list view: 3 parent fields filter child list,

  

My situation:

A) odd thing is that no matter where I put a stop point in my custom field type, it is NEVER hit when the items are displayed in list view.  Event with <Field Name="CAMLRendering">TRUE</Field> which causes the list to error out, but again no stop point to help me know why.

B) the value of the column in question will be different for every user who views the list, I'm querying a secondary list based on the user's loginName, and two of the fields from the list we're in. 

C) the display is customized based on whether any records were returned and the current DateTime, so possible displays would be "", "! 12/1/2010", and "7/7/2011"

D) and the text displayed links over to a form for them to do their assignment. the link url would be a config setting url + "?[one of the fields form the list we're in]"

My questions:

1) Is it possible for fieldtype code to execute while a list view is being rendered?

2) If not, then should I chase down the path of a content query webpart?  Will it be able to filter on the current users login name?

3) If not on 1 or 2, can you think of any other way to do this beyond creating a custom application page? (need to having filtering and sorting on this page)


Disable filtering on a Dynamic Data list view.

  

I have an entity set of NotificationTemplates, and each one of these has a collection of zero-many SmsTemplate entities. When editing or viewing a NotificationTemplate, I have a link to View SMS Templates. That link takes me to a List view for the SmsTemplates entity set, filtered for the NotificationTemplate I was viewing.

How can I prevent the user changing this filter to show SmsTemplates for another NotificationTemplate? That is, I want the filter, but it must be read only. The drop-down just mustn't drop down, it must just display the name of the NotificationTemplate that these SmsTemplates belong to. To view SmsTemplates for another NotificationTemplate, the user must click View SMS Templates from that other template.


This was originally asked by myself on SatckOverflow at: http://stackoverflow.com/questions/3514373/disable-filtering-on-a-dynamic-data-list-view



Entity Data Model and database view returning the same columns as there are in a table

  

When adding a stored procedure into the Entity Data Model I can select whether the procedure returns a scalar, a (new) complex type or one of the entity types I already defined. 

How do I do something similar for a view?


I mean assuming I have a view like this

CREATE VIEW FilteredFoos as SELECT Foo.* FROM Foo join ... WHERE ...

(that is a view that implements some involved filtering, but returns all columns from one table) how do I add it to the project so that I can use the entity set, but get the Foo objects, not some new FilteredFoo objects.


var foos = myDB.FilteredFoos.Include("Bar").ToList();

foreach (Foo foo in foos) { ...

calculate fields in a list

  

hi..

how do I go about generating formulas for something like this.

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.

 

 


Required columns on list; how can I reset them to be NOT required?

  
I have a user list where several fields in a sharepoint list that were originally created as required, but would now like to make them not required. I have already tried simply unchecking the required field checkbox, but that does not work. Any other ways to do this?

How to create scrolling table for columns in a SharePoint Designer Data View

  

I have a fairly complex SharePoint Designer 2007 Data View they have added two more requirements.

1. Have the columns on the right side be able to scroll left to right as there is a large number of columns, while the first 3 columns on the left side stay locked in place.  This is only one list not two, and because of some other requirements I have it must remain to be just one list.

2. Then they also need to have scrolling up and down of the entire list with the headers locked in place.

The first requirement is more important than the second, but preferrably I need to do both.

I am new to XSL so not familar with the syntax. Is this something I can do on a custom Data View? Does anyone have any examples of how?

I have a drawing that show how it needs to look but I don't see an option here to upload a graphic.

So here is a link to my graphic example uploaded to my blog area: http://lindachapman.blogspot.com/  or just the image here: http://4.bp.blogspot.com/_aB01ue__NvQ/TGL42MOvrGI/AAAAAAAAAA4/c3xP4uCy4BU/s1600/Scrolling.png

I failed to mention that 3/4 of the columns are HTML Calculated fields wh
