SharePoint online SUBSITE authentication using client object model :

Are you looking for the perfect solution to authenticate and get data from SharePoint online subsite 2010 (SPO) using client object model?

You can find following sample projects to connect authenticate SharePoint online site content using client object model,

• ·        Remote Authentication in SharePoint Online Using Claims-Based Authentication (http://msdn.microsoft.com/en-us/library/hh147177.aspx)

This article has given brief overview of claims-based authentication and client object model for remote authentication in SharePoint Online. You can download sample code which demonstrates technique of adding SharePoint authentication cookies to the ClientContext object. Solution prompted a dialog window where user have to enter their Office 365 credentials, use the same cookies to the SharePoint client side object model (CSOM) to get SharePoint site content.

But what should I do when I don’t want to show prompt form to enter user details, because I am accessing sharepoint content in Azure site. So I started to check the solution where I can provide user credentials from the code.

• ·        “Headless” Authentication with SharePoint Online and the Client Side Object Model (http://blogs.msdn.com/b/cjohnson/archive/2011/05/14/part-2-headless-authentication-with-sharepoint-online-and-the-client-side-object-model.aspx)

This sample queries the Office 365 STS directly using the Windows Identity Foundation (WIF).  WIF helps with managing the security tokens and requests to the STS. 

Great! This is what exactly I was looking for, it is very good solution.

Project executable solution works fine with the root site. I was trying to query for SharePoint online subsite using the same code but giving (404) NOT Found error for Subsites. When I debugged the code, found following line

Wreply = samlUri.GetLeftPart(UriPartial.Authority) + "/_forms/default.aspx?wa=wsignin1.0"

For root site it gets the correct reference like https://site/_forms/default.aspx?wa=wsignin1.0 and if you used same code to query SharePoint subsite it will give you (404) Not Found because if you try to browse https://site/subsite/_forms/default.aspx?wa=wsignin1.0  browser will show 404 not found error.

Conclusion:
Make following changes on ‘MsOnlineClaimsHelper.cs’ file,

-          Find following line in CS file,
Wreply = _samlUrl  + "/_forms/default.aspx?wa=wsignin1.0"

-          Update same file with following changes

Uri samlUri  = new Uri(_samlUrl);

var sharepointSite = new

         {

                Wctx = office365Login,

                Wreply = samlUri.GetLeftPart(UriPartial.Authority) + "/_forms/default.aspx?wa=wsignin1.0"

         };

                Above changes works for me! Let me know if you want any more information.

SharePoint 2010 : how to open Modal Dialog in ECB Menu

You can open model dialog in SharePoint site using the following code:

<script type="text/javascript">

function openDialog() {

     var options = {

          url: "demopage.aspx", 

         width: 600,

         height: 300,

         title: "My PopUp",

     };

     SP.UI.ModalDialog.showModalDialog(options);

 }

</script>

<div>

    <a  onclick="javascript:openDialog(); return false;">Click Herea>

    <asp:Button ID="btnDialog" runat="server" Text="Open Dialog"  OnClientClick="javascript:openDialog(); return false;"/>

</div>

But what if you want to open dialog from ECB menu? Create new custom action in Element.xml file and in UrlAction tag use the following javascript function.

<Elements xmlns="http://schemas.microsoft.com/sharepoint/"> 

    <CustomAction

        Id="{B0B5A0CB-7FBE-4dd6-9B2A-2B1E1321B8F9}"

        RegistrationType="List"

        RegistrationId="101"

        Location="EditControlBlock"

        Title="Goto My Blog">     

        <UrlAction Url="javascript: function onClose(){ }

          var o = {

            url: 'http://www.niteen.co.cc',

            title: 'MyBlog',

            allowMaximize: true,

            showClose: true,

            width: 700,

            height: 500,

            dialogReturnValueCallback: onClose

          };

          SP.UI.ModalDialog.showModalDialog(o);"/>

    </CustomAction> 

</Elements>

In above code, I created new ECB menu for “Document library”, you can create ECB menu for any lists by changing RegistrationId , you can find all required Register Id here.

If you are not able to see modal dialog then change the <UrlAction> tag with following function.

<UrlAction Url="javascript:(function () {

        var o = {

        url:'http://www.niteen.co.cc',

        title: 'MyBlog',

        allowMaximize: true,

        showClose: true,

        width: 700,

        height: 500

        };

        SP.UI.ModalDialog.showModalDialog(o); }) ();"/>

How to resolve "The language-neutral solution package was not found" error?

Many of developers faced with this error while deploying SharePoint solution from Visual Studio.
I tried many different ways to solve this error like


Delete the following folders from the project directory(In Visual Studio, Right click on project in "solution explorer" window and select 'Open folder in Windows Explorer' ;) )

• bin
• obj
• pkg

and then IISRESET (Goto start > Run > and write IISRESET and press ENTER ) 


Sometimes it works but not every time, So what is the another solution to remove this error while deploying?


Here is simple tric to resolve this problem.. :)
Just open powershell (or Sharepoint management shell) and execute following command,

(get-spsolution YourSolution.wsp).Delete()

that's it.. now you can deploy solution without getting "The language-neutral solution package was not found" error.
*Note: Change "YourSolution.wsp" name to your WSP file name.

Change Sharepoint site home page to Sub-site page

Sharepoint 2010 has given top ribbon from where you can change any sharepoint page as home page for current site by "Make this page as Home page"

But there is one limitation, you cannot assign sub site pages as top site home page.

Then how could you do this change? Is there any way to change default home page to the sub-site pages? Even you cannot change default home page from IIS.

I googled for this and found another way to change default home page path. You have to change into web.config file of Sharepoint site(you can find web.config by looking at Local_Drive:\Inetpub\wwwroot\port_number or check this blog for more details http://blog-sharepoint.blogspot.com/2009/12/where-is-sharepoint-webconfig.html )

Edit your site web.config file with following lines (under system.web )

<urlMappings enabled="true">

<add url="~/" mappedUrl="/french/Pages/Default.aspx"/>

</urlMappings>

Save above changes to web.config file and reset IIS. And now browse for the site, you will see the changes.
you can change default home page in both Sharepoint 2010 and MOSS 2007.

SharePoint Manager 2010

The SharePoint Manager 2010 is a SharePoint object model explorer. It enables you to browse every site on the local farm and view every property. It also enables you to change the properties.

Really very useful for SP developers and admins!


You can download Sharepoint Manager 2010 from Codeplex.

How to get approvers user name in workflow?

When you assign workflow task to any group and how would you get task approvers user name? Task list can show only 'assigned to' column which will give you group name only.
You can fetch approvers user name by creating custom List item event receiver for task list. Create Item updated event receiver and add following code...

public override void ItemUpdated(SPItemEventProperties properties)
{
        base.ItemUpdated(properties);

        SPListItem oListItem = properties.ListItem;
        oListItem["ApprovedBy1"] = properties.UserDisplayName;
        oListItem.Update();
}

*Note: Create new column for workflow task list. I created new column with 'ApprovedBy1' name.
