Office App Model Samples

Office App Model Samples (AMS) is a community driven project. This provides sample and patterns for SharePoint and Office App model development. The highlights of this project are:

Provides ready to use code for common scenarios
Code includes for Office365 and on-premise
Provides Examples, Guidelines, and Reference Codes
July 2014 release has Components, Samples, Scenarios, and Solutions
Bundle of code can also be used for knowledge gain

Another important note here is, we can also provide feedback to the team on scenarios which are not covered in the release. This project really speed up the learning curve and also saves lots of time in development. I've already downloaded the package and excited to go through these samples.

How to get SharePoint List or Library GUID via REST

Sometimes, you would need List or Library GUID to use that in some operation. In such cases, how do you get hold of GUID using REST API? There is a straight-forward end point which you can use: /_api/web/lists/getByTitle('ListTitle')/Id This will return the GUID of a List or Library. There is also another approach. However this approach works only if a List or Library contains at least one item. /_api/web/lists/getByTitle('ListTitle')/items This is a familiar end point which we use to fetch items of a List or Library. To get the GUID from the response, you would do: var listIDTemp = response.data.d.results[0].__metadata.id; var listID = listIDTemp.substring(listIDTemp.lastIndexOf("guid") + 5).split('\'')[0]; As you can see, we are doing string operations to fetch GUID from metadata.id. This contains information only if the response has at least one item.

Get User Id using REST or JavaScript Object Model

Sometimes you would need to fetch the User Id based on either Login name or Email id. You would need User Id if you need to assign a user object to a people picker control or People/Group field. How do we get the Id based on Email or Login Name in client side development? We can achieve that using JavaScript Object Model or REST API. Let me share the first example using JavaScript Object Model (JSOM). var context = new SP.ClientContext.get_current(); this.user = context.get_web().ensureUser(loginName or Email); var o = { d: d, user: this.user }; context.load(this.user); context.executeQueryAsync( Function.createDelegate(o, ensureUserSuccess), Function.createDelegate(o, Fail) ); The above code fetches User Id for a given Login Name or Email Id. Interestingly, there is no equivalent endpoint available in REST! The Microsoft documentation talk about a endpoint but I could not get it working. So what is the way to get User Id using REST? You have to use the hidd

All about SharePoint List View Styles

Sometimes, there are out of the box features which we tend to ignore and later when we do apply, we are more than happy about the feature which is readily available in SharePoint. One such feature is List View Style. I never thought I would write a post on this. However, whenever I spoke about this with users, people were excited to see the result. That prompted me to write this post. Instead of getting into only theory part, I will basically take use cases where these styles can be applied and also touch up on on some minor limitations with certain style. When you are creating/modifying a List view, you will get an option to select View Style. As shown below, there are 8 options available and Default is always set if you ignore this style. List of View Styles I will take typical Contact List and Announcement List to explian about these styles. Let us go one by one. Default: This view, as name suggest, is the default style in a view. This is one of the widely seen style
