Sandboxed Solution Issue

Posted By:      Posted Date: October 13, 2010    Points: 0   Category :SharePoint
I have an issue in using Sandboxed Solution on SharePoint 2010 Enterprise Svr. I have created & deployed a webpart as a Sandboxed solution, when i try to add webpart in page i'm getting "The sandboxed code execution request was refused because the Sandboxed Code Host Service was too busy to handle the request"

I googled this error and tried below three solutions, but it did not help...

1. Started "Microsoft SharePoint Foundation Sandboxed Code Service" service from "Manage services on server" option
2. $acl = Get-Acl HKLM:\System\CurrentControlSet\Control\ComputerName 
$person = [System.Security.Principal.NTAccount]"Users" 
$access = [System.Security.AccessControl.RegistryRights]::FullControl 
$inheritance = [System.Security.AccessControl.InheritanceFlags]"ContainerInherit, ObjectInherit" 
$propagation = [System.Security.AccessControl.PropagationFlags]::None 
$type = [System.Security.AccessControl.AccessControlType]::Allow 
$rule = New-Object System.Security.AccessControl.RegistryAccessRule($person, $access, $inheritance, $propagation, $type) 
Set-Acl HKLM:\System\CurrentControlSe

(Imperfect) Solution to TreeView Postback / Client-Side Node Selection Issue


I've seen this question posted on all corners of the web... "How do I disable "AutoPostBack" on the ASP.NET 2.0 TreeView control?!"  Unfortunately, most of the answers either don't work, miss the point (don't work right), or boil down to "You can't do it."  I happen to know that this behavior worked perfectly in the IEWebControls TreeView that Microsoft released as an add-on prior to ASP.NET 2.0, however.  So I set out to find a solution for the ASP.NET 2.0 TreeView issue.

In a nutshell, the behavior that I and others are looking for is to have a TreeView rendered in a page that allows the user to expand, contract, and select nodes within the TreeView without causing a PostBack to the server.  This implies two things: (1) the most recently-selected node should be recorded as the currently-selected node [i.e., at PostBack time, the most-recently selected node is actually represented as the SelectedNode]; and (2) the selected node should exhibit the SelectedNodeStyle as specified in the TreeView declaration.

It appears that the TreeView engineers saw only two possible outcomes from selecting a leaf node in a tree: (1) immediately posting back to the server, or (2) immediately navigating to another web page.  They apparently did not consider option (3) just allowing selection in-place on the client, while waiting for a click on so

Deploying and Using jQuery with a SharePoint 2010 Sandboxed Solution

If you're an avid reader of this blog, you probably now that I'm quite a big fan of the jQuery Javascript library, especially in combination with SharePoint sites. For a while I've been trying to find a mechanism to deploy jQuery and add a reference to it on all SharePoint pages of a site, by just using a Sandboxed Solution. The first part, deploying the jQuery file, is really easy; this can be done in a Module in a SharePoint project. The second part was more of a challenge; making sure the jQuery file got referenced in all pages of a SharePoint site. My initial thought was to do this by using the AdditionalPageHead Delegate control, but it's not possible in a Sandboxed Solution (you need to deploy the .ASCX to the SharePoint root). My second thought was to use the new ScriptSrc attribute you can use in a CustomAction (I wrote about this attribute some time ago). But initially I was under the impression that the ScriptSrc attribute could only target Javascript files loaded from the SharePoint Root (the \LAYOUTS) folder, resulting in a no-go for a Sandboxed Solution as well. Daniel McPherson stumbled upon this issue as well, but neatly solved it using Javascript to add the reference dynamically. But apparently you can make use of the ScriptSrc attribute to reference files from the Virtual File System (e.g. a Document Library in a site) as well! (thank you Frederic Dobon for men

Deploying sandboxed solution

When I am deploying my sandboxed solution with Power Shell it deploys globally as full trust and not as sandboxed (there is nothing in the solution gallery). Here is my script: ADD-SPSolution -LiteralPath $wspPath Install-SPsolution -Identity $SolutionId -Force:$true -GACDeployment:$true -Local:$true -WebApplication $UrlSiteCollection Enable-SPfeature -Identity $SiteCollectionItemsFeature -Force:$true -URL $UrlSiteCollection The solution is deployed as sandboxed from Visual Studio, but not from this script. Am I missing some option on Install-SPSolution?

Why sandboxed solution cannot load class?

Let's say I have a sandboxed web part with GridView. GridView has sortable columns. I need to store field name and sort order in the viewState. I add two properties to the web part (user control) class:         private string OrderByFieldName         {             get             {                 object o = ViewState["OrderByFieldName"];                 if (o == null)                     return "EmploymentStartDate";                 else                     return o as string;             }             set             {                 V

Is UpdatePanel supported in sandboxed solution?

I have never seen direct answer for this - is Microsoft AJAX (scriptmanager, updatepanel, AJAX control kit, etc) supported in sandboxed solution? If I simply add UpdatePanel into a sandboxed visual web part I get an error saying that script manager is missing. I can add script manager to the control list from code-behind and runtime error goes away, but page does full postback. Is it supposed to work or not? -Stan

Deploying A Solution Issue

I am trying to create a column whereby i can generate a Unique ID for my documents. I have downloaded and installed the UniqueColumnPolicy.wsp from http://blogs.salmanghani.info/?p=570 and i can confirm that in the Central Admin Site under Solution Management the solution has been deployed globally, but i dont see the solution in the List Settings where the article says it should be??? Has anyone any ideas on this? Have i missed a step somewhere?

Opening vs2008 solution file in vs2010 - Framework targeting issue


Hey guys,

I am opening a vs2008 .sln file inside vs2010 - the conversion wizard shows up, and it goes through with no errors other than a pop up warning me that this solution needs .Net Framework 3.5 and that it is "not installed on this machine" - I chose to target it to .Net Framework 4.0 and to try to switch it later as an option.

I then bring up Properties - >Application -> Target Framework and in the dropdown, .Net Framework 3.5 is not listed - which is strange since in "Add or Remove Programs" I can see .Net Framework 3.5 is installed on my machine.

How can I get Framework 3.5 to show up in the dropdown so I can target this project to that framework?

Can't say I've ever done this, so I'm pretty sure I'm doing something wrong.


Update: I tried Method #1 here (http://blogs.msdn.com/b/robvi/archive/2004/02/17/75272.aspx) and I cannot see v3.5 - so where did it go? I'm confused why it is not in my registry but shows up in "Add or Remove Programs" list...


EnsureUser in sandboxed solution (AllowUnsafeUpdates)


I need to get user name (first and last name) for the given login name (MyDomain\TestUser).  EnsureUser does that:

SPUser responsiblePerson = web.EnsureUser (loginName);               
string userName = responsiblePerson.Name;

I am not sure if that is the rigth way of getting user name, because as far as I understand it adds a user to the internal user list and the collection of users.

This is probably why it fails in sandbox solution with dreadful exception below. It does not fail in all cases, though.


Updates are currently disallowed on GET requests. To allow updates on a GET, set the 'AllowUnsafeUpdates' property on SPWeb.

WCF solution to Double Hoop issue


I read about WCF support to resolve the Double hoop issue typical in ASP.NET, is it because of WCF's implementation or just because of WCF's use of kerberos?

Error debugging sandboxed solution: The sandboxed code execution request was refused because the San



I'm trying to deploy a sandboxed solution but I don't succeed.
I created an empty sharepoint project, added a (regular) webpart to it and that's it. Didn't add any code of my own to the project.

Then I hit F5 to deploy it to my sharepoint server (visual studio and sharepoint running on the same machine)

First it gives me an attach security warning, where I hit "attach"
Then a message about scrip debugging disabled where I click ok to enable it.

Then my sharepoint site opens, I log in and it displays my default team site page.
I go edit the page and add my custom web part, and when I click add I get a loading window that seems to hang for a while and then an error:

The sandboxed code execution request was refused because the Sandboxed Code Host Service was too busy to handle the request

I searched google and here on the forums, found several topics describing the same.
I checked and in Central Admin the service "Microsoft SharePoint Foundation Sandboxed Code Service " is started
I also tried to execute the powershell script (even though the server is not running DC)

All to no avail.
Am I missing something here, why do I get this error ?

IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:

MVC2 issue - Stuck. Trying to create a cms with nested partials


I am currently trying to display multiple items on a single page. I am not sure as to how to tackle this. What I have is a database table that has all the page data in. I have this run as a PagesController and this works fine. However what I would like to do is, if say the Products page is selected via the menu, I want to pull back not only the Products page html but also get all the products, and even be able to pull them through via category. I was trying to use a partial view, but I can't get it to work. The same would be for other pages, having partial views to display the other content, ie if Gallery is selected, the page html for Gallery shows and it then can push to a partial view that pulls all the gallery images from the gallery db table and so on. 

Maybe I am tackling this the wrong way. I have the pages stored in the db to allow for a CMS system I have setup. Maybe I need to use models for all the other items(Products, Gallery, Videos and such) and use the partial for the page html?

Any help would be greatly appreciated as I am confused.
