User information list properties SP Foundation 2010

When trying to view properties of user information list in SPD 2010, I get the following error "SharePoint designer cannot display the content of this view (...)" I am logged in as administrator for both farm and site. I can view content of the list in a browser, but I cannot access the list as a lookup column. It works with WSS 3/SPD 2007 on another server.

Update all Properties in the User Information List after restoring a site collection to a new domain


hi All

I moved a site collection (content db) from one domain to another. After the site collection was restored i ran the stsadm -o migrateuser -oldlogin -newlogin. The result was that the login id of the user in the source domain was replaced with the login in the destination domain.

However the rest of the properties in the User Information List (paricularly interested in the Email) was not updated.

How can i get all the properties in the User Information List with values in the new domain

Thanks in Advance


Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

User Defined Functions in Microsoft SQL Server

User Defined Functions are compact pieces of Transact SQL code, which can accept parameters, and return either a value, or a table. They are saved as individual work units, and are created using standard SQL commands. Data transformation and reference value retrieval are common uses for functions. LEFT, the built in function for getting the left part of a string, and GETDATE, used for obtaining the current date and time, are two examples of function use. User Defined Functions enable the developer or DBA to create functions of their own, and save them inside SQL Server.

"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave


<%@ Control Language="VB" ClassName="SimpleCtrl" CodeFile="SimpleCtrl.ascx.vb" Inherits="_SimpleCtrl" %>

    Simple control


Partial Class _SimpleCtrl
    Inherits UserControl

    'Nothing to see here.

End Class


<%@ Control Language="VB" CodeFile="ContainerCtrl.ascx.vb" Inherits="_ContainerCtrl"

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

Crawler fails to register date properties of user profiles with the month of January, April, August


This seems to be a bug when the crawler search the user profiles in MOSS 2007.  When crawled, user profiles with a SPS-HireDate in the months of January, April, August and December will be detected, but a full-text (SQL) search returns those profiles without the HireDate field.

User profiles with HireDates in other months work correctly, returning the HireDate in the search.  And changing the month of a problematic user profile also fixes the problem.

This problem is also reflected in the fact that while we have 499 user profiles using the SPS-HireDate property,  the managed property page from the search section only has 350 items with the HireDate property.

We're running MOSS 2007 32bit with SP2 with an English language base and the Spanish language pack. I'd considered date format problems, but I can't imagine how some months would work, while others wouldn't.

Any ideas?

How to Set a list item's createdby or modifiedby field as a User(deleted from AD)



I have to migrate data from SQL DB to SP list. But its old data and some users who created/modified the record has been deleted from the AD. Now I need to set the CreatedBy / ModifiedBy Field of the item accordingly. How to achieve this?

And when I tried to modify the "Editor" and "Author" field through Object Model, it works. But its not working through Webservice. What is the reason behind this?

Please help me find an optimal solution for this...


Thanks and Regards,

Problem with User Control Properties


I've been trying to figure out a problem that I've had for the past week and believe that the issue is something with a user control that I created. In short, the properties for the user control are recognized by intelisense when I register the control and then add it in the markup for a page. However, the values that I set in the markup are ignored by the class as if the properties don't exist.

 <%@ Register Src="../../controls/contactdetail.ascx" TagName="ContactDetail" TagPrefix="tfc" %>

<tfc:ContactDetail runat="server" ID="UserControlContactDetail" Title="Contact-Detail" ContactId="1580" EnableViewState="true" />   



User Control Class

Imports System.Data
Imports System.Data.SqlClient

Partial Class control_ContactDetail
    Inherits System.Web.UI.UserControl
    Public Property ContactId() As Integer
            Return _ContactId
        End Get
        Set(ByVal value As Integer)
            _ContactId = value
        End Set
    End Property
    Private _ContactId As Integer
    Public Property Title() As String
            Return _Title

Creating a table-valued function on a user defined type in SQL Server CLR

We would like to be able to create a table-valued function on a user defined type.  We would like the syntax in SQL to look like it works for the XML nodes function:   DECLARE @myXml XML = '<a><b>1</b><b>2</b><b>3</b></a>' ; SELECT  node.query('text()') FROM    @myXml.nodes('a/b') nodes (node) ;   In other words, in the FROM clause, we can access the "nodes" method of the xml variable and it returns a rowset. Thanks!

User Alert Management for a specific list versus entire SharePoint site?

It seems that to be able to manage User Alerts, one must have Full Access to the entire SharePoint site - and then use => Site Settings > User Alerts. Ideally, I would like to be able to grant access to users to only be able to manage alerts for a specific list. Is this possible (without having to do any programming) and, if so, how? If such access is only available at the site level, I will simply create a Permission Level that allows one to only "Manage Alerts" Thanks in advance for any assistance. Dave
