Lookup Column Data on seperate Subsite

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :SharePoint
 

Is there a way to make a look up reference a column on a seperate subsite?  I was thinking I could do it with BCS but I seem to be having an issue setting up a MOSS 2010 list as a source.

Basically I have SubSiteA with a list that includes some catalog information for systems and SubSiteB is a Doc Center that contains various atricles about the systems. I want to have one column in SubSiteB reference a Column from SubSiteA to use as metadata for search/filter purposes.

 

Any thoughts?  Thanks

Paste data in a lookup column

  
Hi all, I am trying to create a Sharepoint list from a previous Excel file and I would like to use a lookup column, to allow users to pick values of “column B” from “column A”. The values are already entered in "column A", so now I would like to edit the list in datasheet view and copy/paste the values from my excel file into my “column B”. It works well when I copy/paste only one data, but when I try to paste several values in the same row (using a semicolon as delimiter), I get the error message “Cannot paste the copied data due to data types mismatches or invalid data.”, although the column is set to allow multiple values. I noticed that lookup columns allowing mulitple values store items with the item ID, as follows: ITEM NAME;#ITEM ID, but don’t display it in datasheet view or standard view, and I guess this is why I can’t copy and paste the data from my excel file since they don’t have the ID encoded, but is it possible to do it anyway? Thanks for your help.

lookup column data not visible with REST

  

Using Designer 2010 and a data view web part, the Lookup column data, is not showing when I reference my list with REST. Is there something special I need to do to be able to see this data? I came across an article that talked about lookup data not being part of the physical list. Is that relevant?

Thanks in advance for any help


Rendering data with HTML tags in the DD Gridview for a selected column

  

I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                // Html Encode the cells
            }

        }

but this event never fires?


Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

split one data column into many?

  

Hi, I've a database table contains survey questions and answers. But the problem is both 'question' and 'answer' are saved in the same column(like below).

SubmissionDate                                                          Submission

2010-02-15 14:53:59.657                     ***What's your pet's name?***  Lili ***Tell us about yourself*** I'm a teacher

2010-02-15 14:53:59.657                     ***What's your pet's name?***  Lucy ***Tell us about yourself*** I'm a five star cook


I'd like to use a simple datagrid to display the survey result, but I need to separate the submission column into multiple columns ('question' as column name, 'answer' as data)

the number of questions or questions being asked are different for each survey so they are not fixed. 

Is it even possible to get something like this below in a gridview?

Business Data Column cascade

BD Column 2 called City with all the cities based on the state selected on BD Column 1


Use BDC data in list as multi-select column

  
I have a document library that uses values from another system for its metadata.  Right now, we copy the values from the primary system into SharePoint so users can choose them.  I want to find a way to use the BDC connection that I have set up to automatically pull those values.  The problem is that the current metadata is set to multi-select.  So, I have a file that is in the library and it can be used for multiple clients - clients is a column in my library and users can select many entries.  When I set up a column to pull BDC data, it only allows single entry.  Does anyone have any ideas?

wss2.0 update/delete/hide lookup column that does not display any values

  

Hi All,

I have a document library that contains a Category column that is a lookup field. This is a default column that is a required field when uploading documents to the document library. The Category column is empty and I am unable to amend, hide, make it not required or delete it.

I have gone to Modify settings and columns -> clicked on the Category field to edit, but there is no option to amend the content or delete it. I am only able to amend the Column name and Description.

Since then, I have amended the column name to eg. Category1 and created a new Category field as a lookup and linked it to the correct list.

The problem I am facing now, is that I cannot hide, delete or make the Category1 (old Category) field NOT required. Either I would like to update the original field to display the correct values or alternately hide, delete or make the column not required.

Please help.


Datasheet view lookup column issue

  

When a column that has a lookup is empty in datasheet view and I attempt to update a different column I get this message: the text entered for isn't an item from the list. select an item from the list, or enter text that matches one of the listed items.

I found this hotfix, but it did not apply.

Any ideas how to get this resolved?


Hide data for specific column from a user

  
Greetings, I have a problem. I would like to restrict showing specific users (or roles or schemas) data in a column. First I thought DENY option will do it but figured out that it won't. DENY denies the column being in the SELECT query. I would still like to call the column but if access to the data in that column is restricted it would show only null values and not the real ones. So... I would like call the next query from user TestUser: SELECT ID,Name,Address FROM Employee But if access to Address is restricted for TestUser I would get results like: ID Name Address 1 John Smith NULL 2 Rick Ross NULL ... Is it possible to do something like that in SQL Server 2005/2008? I was thinking of storing that kind of information in a table (for which tables, which columns for which users access is restricted) and then manipulate it on the application site but my programmers tell me that they use components which always call the full table (like SELECT *).  Thank you for your answer.

How to perform math on a column of data in SQL database and display it in my VB app

  
Sorry if this is the wrong forum, cos it's SQL and VB2010 So I have my sqlserver database 3.5 compact editon called "Dive Club Records" and in it are stored columns of dive trip information and I want tthe user to be able run a query from my VB2010 application to sum a divers total dive hours and display it on the form, eg: MemberID, FirstName, LastName, DiveTime by the way divetime is a real number recorded as 15.5, 20.5, 5.0 etc What is the easiest way to do this? Would prefere to do it from within VB2010 code if possible or make a query from the datagrid on my form using query designer. thanks for any suggestions from you all, hope you can keep them simple for me :)   regards   paul   paul
