few things you should NOT do when deploying Office Web Apps Server

First, here are a few things you should NOT do when deploying Office Web Apps Server.

  • Don’t install any other server applications on the server that’s running Office Web Apps Server. This includes Exchange Server, SharePoint Server, Lync Server, and SQL Server. If you have a shortage of servers, consider running Office Web Apps Server in a virtual machine instance on one of the servers you have.

  • Don’t install any services or roles that depend on the Web Server (IIS) role on port 80, 443, or 809 because Office Web Apps Server periodically removes web applications on these ports.

The file that i want to open have url like http://blog.bugrapostaci.com:80/_layouts/xlviewer.aspx?id=/Shared%20Documents/CaseTest.xsls
But  the important one is in logs   in this correlation that unrelated information log not the exceptions. This info is about :
“There is no Web named “/SiteDirectory/BlogContent/Lists/Categories/AllCategories.aspx”. in first i ignored it quickly. Than i realized that article:

Excel Calculation Service cannot display workbooks if no root site collection is created for a web application.

The sharepoint version which i was working on it is before Oct 2011 CU . The Solution is simple install at least Oct 2011 CU for fixing these errors.

Sharepoint 2010 Character problem in Category Titles in Blog Site for different languages

Hello Everyone,

If you faced a character problem in Category Titles in Blog Site Template for different language , may be this article helps you. In my envoriment i am using Turkish Language Pack (1055) .
the repro is not tested on other languages but it  should be occurs for other languages which is contains specific characters .

I think this  problem is a minor bug .You can reproduce it easily .

Here the Repro steps.
1) Install or find SPS2010 + SP1Dec2011 CU + TR(1055) language pack installed machine.
2) Create a site collection in Turkish
3) Create a “Web Günlüğü”  (Blog Site Instance)
4) Add some categories that contains Turkish Characters.
5) Click one of this category titles in left navigation  and open category page

I have created a category named : “Yağlı Boya Seçmeleri”  You can see the problem bellowed screenshot.

The problem is when rendering left panel Categories web part (XSTLListView) not encode url of Link object correctly. I have tested with changing the link in browser’s address bar with correct encoding the titiles shown correctly on category page.

So There  is a workaround for fixing this issue with using Sharepoint Designer 2010 .

1) Open defauılt aspx and (any needed page) in Sharepoint Designer.

2) Select one of the link  in Categories  XsltListViewWebpart


3) Click the HyperLinkOptions button.

4) Change the default value of
{$HttpVDir}/{$thisNode/../@resource.wss.lists_Folder}/{$thisNode/../@resource.wss.blogcategories_Folder}/Category.aspx?CategoryId={$thisNode/@ID}&Name={$CategoryTitle} as
{$HttpVDir}/{$thisNode/../@resource.wss.lists_Folder}/{$thisNode/../@resource.wss.blogcategories_Folder}/Category.aspx?CategoryId={$thisNode/@ID}&Name={$thisNode/@Title}

5) Repeat same options for all needed pages.

And Open and Check  again your blog page :

(For who know Turkish the word of “Şeçme” have a little typo correct word is “Seçme” . Dont worry about it . i am not get all screenshot again for fixing this 🙂

See you next article.

TaxonomyWebTaggingControl – Sharepoint

Hi guys , in this article i will tell you how to use TaxonomyWebTaggingControl . First of all i assume that you already define your terms and terms sets in your sharepoint managed meta data service.This control help us that show and set this terms for various purpose. Msdn says “A TaxonomyWebTaggingControl object is a Web control that can be added to a page so that a user can pick one or more taxonomy Term object from a specific TermSet object or from an entire TermStore object.”

First we register control in our page definition.

<%@ Register Assembly="Microsoft.SharePoint.Taxonomy, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"
    Namespace="Microsoft.SharePoint.Taxonomy" TagPrefix="cc1" %>

And control in the content like this

<cc1:TaxonomyWebTaggingControl ID="TaxonomyControl" runat="server" >
</cc1:TaxonomyWebTaggingControl>

At code behind we getting taxonomy store from metadataservice and set the control properties

Dont forget to add your libraries.

using Microsoft.SharePoint.Taxonomy;
using Microsoft.SharePoint;
And your code here
SPContext context = SPContext.Current;
SPSite site = context.Site;
TaxonomySession session = new TaxonomySession(site);
TermStore termStore = session.TermStores["Managed Metadata Service"]; //if you a custom meta service you should change name.
Group group = termStore.Groups["MyGroup"];
TermSet productsTermSet = group.TermSets["Genders"];

.the code above just getting metadata objects from service via using taxonomy entities.

In my code i am usign UserProfileService which has a user property named “Gender” means “Male,Female” which is defined in metadataservice. I am going to set TaxonomyWebTaggingControl (ID: TaxonomyControl) and get value from this control.

Bind the control with entities

TaxonomyControl.SspId.Add(termStore.Id);

TaxonomyControl.TermSetId.Add(productsTermSet.Id);

TaxonomyControl.IsAddTerms = true;

TaxonomyControl.AllowFillIn = true;

TaxonomyControl.IsMulti = false;

Setting data to control with userprofile object:


string
termName = service.GetUserPropertyByAccountName(loginName, ProfileProperties.Genders).GetSingleValue();// don’t worry about this line this is not in our concept.Just know this line getting value from UserProfileService as string.

TaxonomyControl.Text = string.Format(“{0}|{1}”, termName, productsTermSet.Terms[termName].Id.ToString());

TaxonomyWebTaggingControl has a propery named “Text” . You should set this property  “[Label] | [Guid]” format.
Set values into this control as pairs of labels and GUIDs. The delimiter between a label and a GUID is the | character. When using multiple values, delimit them with a ; character. Example: term1|12345678-1234-1234-1234-123456789012;term2|87654321-4321-4321-4321-210987654321

Getting data from control :

TaxonomyFieldValueCollection portfolioCountriesValues = new TaxonomyFieldValueCollection(String.Empty);

portfolioCountriesValues.PopulateFromLabelGuidPairs(TaxonomyControl.Text);

profile[ProfileProperties.Genders].Value=  portfolioCountriesValues[0].Label;

We are using TaxonomyFieldValueCollection class that help us parsing data.
