October 19, 2009 at 11:09 AM There are different ways of adding your own custom actions to the ribbon in SharePoint 2010. The ribbon is made up of tabs and groups. Each tab consists of Groups. So when we want to add a custom action we need to identify the correct tab and group. This is referenced by Tab.Group ID. 1. SharePoint Designer Using SPD 2010, open the list that you want to customize. You can see the Custom Actions section on the page.

October 19, 2009 at 11:07 AMEnterprise Content Types and Service Applications are interesting features of SharePoint 2010. Enterprise content types can be used to provide a consistent entity definition to different web applications. Consider an example of a textile company who has implemented an Extranet and an Intranet application. Their clients can log on to their extranet site and order different products. To add a product the client needs to fill up a form. The form data will be stored in a list on the extranet. The li

December 21, 2008 at 11:06 PMLast week we came across a very interesting problem. A routine deployment made some of the web parts throw an exception whenever you made a change to its properties and tried to save the changes. This exception was also seen when we tried to add a web part to a page. It was not only for custom web parts but also for OOTB (Out of the box) web parts. Now what could have possibly happen that would make the OOTB web parts break and throw an exception. Looking into the issue, I found that the culprit

December 21, 2008 at 11:04 PMI don't know how or why but sometimes the fields in a content type can get hidden. And you wont get an option of un-hiding the field using the UI. Actually if you try and un-hide the field using the object model, it wont let you. The CanToggleHidden property will be false. And the object model does not allow you to reset this property. There is a way to reset this property. The following code uses reflection to invoke the right method and reset the property. After the code executes the field (SP

December 21, 2008 at 11:00 PM I saw some applications making use of the carosel to display their products and that made me think. What if I had a set of products related to each other. Like if I was displaying Vaccum cleaners then clicking on of the vaccum cleaners would show me another carousel which would display different accessories for that vaccum cleaner. We can architect this by creating different entities. 1. Carousel - This class handles the items in it and rotates them at the set speed. 2. Carousel Controller -

September 7, 2008 at 9:15 PM To implement a search UI quickly, we can use the content editor web part to generate the UI. After you get the UI on track, how do you get the search working. 1. Add the search core results web part to the page. 2. Configure the search core results web part: a) Set the number of results to display. b) Set the selected columns that you want to display. These columns are basically managed properties which can be changed/added in the shared service provider. Once you add the co

August 13, 2008 at 11:23 AM According to the current implementation you will get an error when you click on Attach File link. I guess most of you have seen this dialog box some time or the other after customizing the edit or new forms for a list. The problem: The JavaScript is trying to find the element “part1” (which is the ID of the table which has all the field controls) and though we have set the ID of that table to “part1”, the JavaScript does not find the element. The cause: Since we have rendered the inpu

August 12, 2008 at 10:21 PM To develop an edit/new/display form for a SharePoint list we have to implement the following steps: Get the list. Get the collection of all the columns If the form is in EDIT mode, get the item which is being edited. Render the columns that you want according to your requirements. Add the Save, Cancel buttons to the form and add the handler to it. The first 3 steps are pretty straightforward. All of this information is available in the query string and SPContext.

August 12, 2008 at 10:21 PM Accessing the values of the controls is actually very easy. All the controls that you render using the FormField class are collected and stored in a collection. This collection resides in the current FormContext. To access the collection use the following statement: SPContext.Current.FormContext.FieldControlCollection This collection has all the fields that were rendered using the FormField class. The FormField class when instantiated registers itself in the FieldControl collection. Toolbar

Often we need to add more tabs to the global navigation of a MySite. By default, you get to see "My Site" and "My Profile" and even if you add more links using the Top Link Bar tool in Settings page, they wont show up in the Top navigation.This is because the provider specified in the web.config for the MySites Navigation ignores the Global navigation nodes specified by the user.
This is the provider for the mySites in the web.config.

If this happens, you don't see the column in the list settings, but if you try and create a column with the same name, Sharepoint throws an error saying that a column already exists with that name. If you try and add a site column to the list, it creates the column in the list with the Display name as what is required, but the internal column name is the column name + 0 e.g region0, budget0 To delete this colum

February 16, 2008 at 10:45 AM If you want to try and modify the Display Form of a document library using SPD, you should be aware of the following problems: Deleting the existing web part on the page and adding new content might break the document library. (When you click on View Properties of an item, it redirects the user to the root site) Modifying the existing web part, might work but it could break the edit forms functionality.

April 26, 2007 at 11:52 AMScenario: Workflow is waiting on the OnItemChanged event of a SP list. We need to update the same item from the workflow.
Solution:
Do not use the Update method of SPListItem. This will surely make the workflow go into recursion.
Instead add a CallExternalMethod Activity.
Select the interface type as IListItemService
Method : UpdateListItem
Bind the following properties:
1. ListId : Bind to the workflowproperties.ListID
2. ItemId : Bind to the workflowproperties.ItemID
3. Id.

This sharepoint site gets accessed locally from a port other than 80.If you develop a custom aspx page then you would generally put the page in the _layouts folder and the dll in the Bin folder of the Site:port Virtual directory.The page would work fine if the user accesses the site from the Intranet using the local url i.e http://site:portBut try accessing the page using the mapped URL.

Before I start with my articles, I would like to explain why I have named my blog as Axon.
The nervous system consists of a large number of cells, called neurons. Each neuron has numerous extensions called dendrites. These extensions receive chemical signals from other neurons. An Axon is a little different from dendrites. It is responsible for transmitting signals to other neurons over considerable distance.
Now compare this with our work environment. Each individual is a processing unit,
