You cannot customize permission levels in a web site with inherited permission levels. at Microsoft.SharePoint.SPRoleDefinitionCollection.Add(SPRoleDefinition role)

Okay simple solution here: Make sure that if you are not the root SPWeb and you want to add custom role definitions i.e. SPRoleDefinitions call SPRoleDefinitionCollection.BreakInheritance(bool,bool)

if (!web.IsRootWeb && !web.HasUniqueRoleDefinitions)
{
      web.RoleDefinitions.BreakInheritance(true, false);

Server Out Of Memory – There is no memory on the server to run your program. Please contact your administrator with this problem. at Microsoft.SharePoint.Library.SPRequestInternalClass.ApplyWebTemplate(String bstrUrl, String& bstrWebTemplate, Int32& plWebTemplateId)

There are lots of reasons this error message can occur, see: http://www.google.com/search?q=sharepoint+Server+Out+Of+Memory. In my case it happened when a new site was being provisioned using a custom site definition during the ApplyWebTemplate call.

Turned out the there were subtle errors in my onet.xml. In particular I was referencing some document templates using an incorrect path:

<Project Title="$Resources:onet_TeamWebSite;" xmlns="http://schemas.microsoft.com/sharepoint/"  Revision="2" ListDir="$Resources:core,lists_Folder;" xmlns:ows="Microsoft SharePoint">
  ...
  <DocumentTemplates>
    <DocumentTemplate Path="INCORRECTPATH" Name=""

SharePoint field constants.

I always forget the name of the class that stores a great big list of field ID constants. So as a reminder to myself it’s SPBuildInFieldId

For example:


SPFieldUserValue user = item[SPBuiltInFieldId.Author]

Whilst looking this up again I stumbled across another similar class SPBuiltInContentTypeId that holds content type id’s for the common OOTB content types, neat!

if (this.ContentTypeId.IsChildOf(SPBuiltInContentTypeId.Message))
{
......

Quicklaunch navigation will not show a link if it’s set as the home page.

Today I had the requirement to include a link in the quick launch menu to the current web’s homepage. Agreed it’s a strange requirement, but nonetheless in this case it was arguably not too bad.

However the default SPNavigationProvider does not display the homepage in the quick launch menu. In order to do this add the link as an external page, even though it’s not.

using (SPSite site = new SPSite("http://localhost"))
{
	using (SPWeb web = site.OpenWeb(""))
	{
		string url = web.ServerRelativeUrl + "/Pages/MyPage.aspx";
		WL("Adding..." + url);
		
		SPNavigationNodeCollection nodes = web.Navigation.QuickLaunch;				
		SPNavigationNode newNode = new SPNavigationNode("MyLinkTitle", url, true);
		nodes.AddAsLast(newNode);
		web.Update();
	}
}

Shared Services User profile synchronization with WSS user profiles stored in the User Information list

Ever wished that the WSS user profile would update it’s values immediately after you’ve just ran a new SSP profile import. Well I just came across a very cool little tool that does just that. The “User Profile Sync” tool hosted on codeplex.

It’s worth noting that SharePoint has timer jobs that run and perform this synchronization process for you. Hover the above mentioned tool allows you to force this process to occur immediately.

Target Audience property not displaying / missing for web parts

I came across this problem on a web application that had been working fine, then all of a sudden the “Target Audiences” property disappeared from the web part tool pane.

 

To solve this problem I re-associated the web application with the Shared Service Provider (SSP) and bounced IIS.

1. Web applications are associated with SSP’s in central administration. Select Shared Services Administration

sharepoint central administration

 

2.  Select Change Associations

sharepoint central administration manage farm shared services

 

3. Select the web application you are having problems with, and select OK to complete the process.

sharepoint central administration change association between web applications and ssps

4. Perform a  complete IISReset.

Then the property miraculously reappeared – hooray!

Pages - AllCounterParties - Mozilla Firefox (3) ITS BACK!!

 

During investigating this issue I found the class responsible for rendering this section of the tool was an internal class WebPartToolPartAdvanced. I you really get stuck and my method doesn’t cut it you could dig around in that class and see if you can find anything that helps.

Unknown SPRequest error occurred. More information: 0x80040e14 – Exception from HRESULT: 0x80040E14

If you get ever get this error message and you are rolling out your own list definition, chances are you messed something up in the shema.xml file.

The first place to look is the event logs. In my case today this was caused due to an incorrectly mapped column name in the field element. The log files gave the clue:

Unexpected query execution failure, error code 8143. Additional error information from SQL Server is included below. "Parameter '@sql_variant1' was supplied multiple times." Query text (if available): "SET NOCOUNT ON; DECLARE @ItemId int,@@iRet int,@ExtraItemSize int,@DN nvarchar(256),@LN nvarchar(128),@@S uniqueidentifier,@@DocUIVersion int,@@Level tinyint;SET @@S='846FD34D-3722-433D-845B-564ACB4037EE';SET @@Level=1;SET @@DocUIVersion = 512;BEGIN TRAN;SET @ItemId=NULL;SET @DN=N'counterparty/Lists/CounterParties';SET @LN=NULL;SELECT @ExtraItemSize = 0  EXEC @@iRet = proc_AddListItem @SiteId = '846FD34D-3722-433D-845B-564ACB4037EE',@WebId='EEFB7523-73C9-4BDF-B2FC-9AA940A0B059',@ListID = 'B6BA34B0-8CBE-4F1F-819C-0460CF82FA35',@RowOrdinal = 0,@ItemDocType = 0,@ItemId = @ItemId OUTPUT,@ItemDir...	 

I had used sql_variant1 twice for the ColName attribute, replacing the duplicate with sql_variant2 did the trick 🙂

SPUtility.DateParse !♥ seconds: SPUtility.DateParse removes the time component if you parse a date that incudes seconds!??!

Okay here’s another baffling API bug:

If you parse a date using SPUtility.ParseDate(web, “11/29/2009 13:37:12”, SPDateFormat.DateTime, false) it will return you a date object without parsing the time!

Remove the seconds SPUtility.ParseDate(web, “11/29/2009 13:37”, SPDateFormat.DateTime, false) and we are good to go. Full program listing of bug follows:

using System;
using System.Collections.Generic;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;

public class SPUtilityParseDateTest
{
	public static void RunSnippet()
	{
		using (SPSite site = new SPSite("http://localhost"))
		{
			SPWeb web = site.RootWeb;			
			DateTime parsedDate = SPUtility.ParseDate(web, "11/29/2009 3:37:12 AM", SPDateFormat.DateTime, false);				
			WL(parsedDate.ToString());
				
			parsedDate = SPUtility.ParseDate(web, "11/29/2009 3:37 AM", SPDateFormat.DateTime, false);				
			WL(parsedDate.ToString());
			
		}
	}
		
	#region Helper methods
	
	public static void Main()
	{
		try
		{
			RunSnippet();
		}
		catch (Exception e)
		{
			string error = string.Format("---\nThe following error occurred while executing the snippet:\n{0}\n---", e.ToString());
			Console.WriteLine(error);
		}
		finally
		{
			Console.Write("Press any key to continue...");
			Console.ReadKey();
		}
	}

	private static void WL(object text, params object[] args)
	{
		Console.WriteLine(text.ToString(), args);	
	}
	
	private static void RL()
	{
		Console.ReadLine();	
	}
	
	private static void Break() 
	{
		System.Diagnostics.Debugger.Break();
	}

	#endregion
}

The above code assumes you have US regional settings on your root web.

SPLimitedWebPartManager.SaveChanges throws Microsoft.SharePoint.WebPartPages.WebPartPageUserException: The file is not checked out.

Got stuck on this one for a long time, more than an hour

Microsoft.SharePoint.WebPartPages.WebPartPageUserException: The file is not checked out.  You must first check out this document before making changes.   at Microsoft.SharePoint.WebPartPages.SPWebPartManager.SaveChangesCore(SPLayoutProperties layoutProperties, Boolean httpGet, Boolean saveCompressed, Boolean skipRightsCheck, Guid& newTypeId, Byte[]& newAllUsersProperties, Byte[]& newPerUserProperties, String[]& newLinks)   at Microsoft.SharePoint.WebPartPages.SPWebPartManager.SaveChangesCore(SPLayoutProperties layoutProperties, Boolean httpGet, Boolean saveCompressed, Boolean skipRightsCheck)   at Microsoft.SharePoint.WebPartPages.SPWebPartManager.SaveChangesInternal(SPLayoutProperties layoutProperties, Boolean skipRightsCheck)   at Microsoft.SharePoint.WebPartPages.SPWebPartManager.SaveChanges(Guid storageKey)   at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.SaveChanges(WebPart webPart)

I was using the following code to update a webpart

gWeb publishingWeb = PublishingWeb.GetPublishingWeb(webSite);
SPListItem item = publishingWeb.PagesList.GetItemByFileName(pageName);
if (item != null)
{
	SPLimitedWebPartManager webPartManager = item.File.GetLimitedWebPartManager(PersonalizationScope.Shared);
	PublishingPage publishingPage = PublishingPage.GetPublishingPage(item);

	try
	{
		if (item.File.CheckOutStatus == SPFile.SPCheckOutStatus.None)
		{
			publishingPage.CheckOut();						
		}					
		else
		{
			item.File.UndoCheckOut();
			publishingPage.CheckOut();
		}

		WebPart webpart = webPartManger.WebParts[0];
		// Do something with the webpart
		webPartManger.SaveChanges(webpart); // Now the exception is thrown
		
		
		publishingPage.Update();
		publishingPage.CheckIn(updateComment);

		if (publishingWeb.PagesList.EnableModeration)
		{
			item.File.Publish(updateComment);
			item.File.Approve(updateComment);
		}
	}
	finally
	{
		if (webPartManager != null)
		{
			webPartManager.Dispose();
		}
	}
}

A quick google reveals quite a lot of other people stumped with this problem. Why is it saying the file is not checked out, the lines above it make sure it’s always checked out to the user running the code. Turns out it’s quite a simple fix. Don’t instantiate the SPLimitedWebPartManager until your done making sure the page is checked out!

Working code

gWeb publishingWeb = PublishingWeb.GetPublishingWeb(webSite);
SPListItem item = publishingWeb.PagesList.GetItemByFileName(pageName);
if (item != null)
{
	SPLimitedWebPartManager webPartManager = null;
	PublishingPage publishingPage = PublishingPage.GetPublishingPage(item);

	try
	{
		if (item.File.CheckOutStatus == SPFile.SPCheckOutStatus.None)
		{
			publishingPage.CheckOut();						
		}					
		else
		{
			item.File.UndoCheckOut();
			publishingPage.CheckOut();
		}

		// Now we're certain the page is checked out, grab the web part manager.
		webPartManger = item.File.GetLimitedWebPartManager(PersonalizationScope.Shared);

		WebPart webpart = webPartManger.WebParts[0];
		// Do something with the webpart
		webPartManger.SaveChanges(webpart); // Now the exception is thrown
		
		
		publishingPage.Update();
		publishingPage.CheckIn(updateComment);

		if (publishingWeb.PagesList.EnableModeration)
		{
			item.File.Publish(updateComment);
			item.File.Approve(updateComment);
		}
	}
	finally
	{
		if (webPartManager != null)
		{
			webPartManager.Dispose();
		}
	}
}

Notice that we assign the value of the web part manager after we make sure the page is checked out. Hopefully this saves someone a couple of missing hours i’ll never get back 🙂

Provisioning a Web Part with a predefined ID in your onet.xml of element manifest.

From time to time you might want to provision your WebParts using the CAML markup and then modify them in a feature later on. Most examples on the web find the webpart based on it’s title. i.e.

foreach(Webpart webpart in webpartManager.WebParts)
{
   if(webpart.Title == "Title I'm expecting")
   {
       // Do something with the webpart
       webpart.AuthorizationFilter = "";
       webpartManager.SaveChanges(webpart);
   }
}

However you can specify the ID of a web part in your onet.xml / element manifest like so:

 <View List="Lists/MyList" BaseViewID="1" DisplayName="Counter Parties" Name="List Nmae" RecurrenceRowset="TRUE" WebPartZoneID="Header" WebPartOrder="1">
        <![CDATA[
               <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2">
                    <Assembly>Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>
                    <TypeName>Microsoft.SharePoint.WebPartPages.ListViewWebPart</TypeName>
                    <Title>MyList - Workflow Users</Title>
                    <DetailLink>~Site/Lists/MyList/AllItems.aspx</DetailLink>
                    <Description>Use this list to store ... information.</Description>
                    <ID>g_45C819FD_FC4C_44e1_81DD_3AE4FCC34D37</ID>
               </WebPart>
            ]]>
      </View>

Create a new Guid replace the hyphens with underscores and add a “g_” to the beginning of the string g_45C819FD_FC4C_44e1_81DD_3AE4FCC34D37.

Now we can reference the web part in your feature receiver using the indexer property, which is I think you’ll agree much more elegant and less error prone:

Webpart = webpartManager["g_45C819FD_FC4C_44e1_81DD_3AE4FCC34D37"]
// Do something with the webpart
webpart.AuthorizationFilter = "";
webpartManager.SaveChanges(webpart);
