SharePoint Saturday Melbourne 2012

/

 

I had a great time in Melbourne and presented my session on Building Custom REST services and consuming them with jQuery AJAX.  Thank you for attending my session and listen to me ranting for an hour.

 

As promised, there are a number of links:

 

There are a few things I missed:

On 2007, you can't easily deploy WCF or REST services to a 2007 installation.  But you can still use Javascript to talk to SharePoint 2007's built in WCF services.  Check:

For 2013, the WCF/REST solutions work fine.  I had a quick test and took some screenshots.

For DataService (ADO.NET / exposing Entity Framework via REST service), see the last feature in the demo project.

 

Drop me a comment if you want to ask me about anything specific and I'd love to geek out!

SP2013 Custom services deploys and runs on v15

/

 

I fired up my SP2013 VM to do some simple tests tonight, I wanted to know if the REST services that I've built and demo'ed for SharePoint 2010 would run in SP2013.  Technically, they should.

So I deployed:

  • stsadm -o addsolution -filename .\SPGSvcWp.wsp
  • stsadm -o deploysolution -name SPGSvcWp.wsp -local -allowgacdeployment -allcontenturls

 

The files are copied to the services OK.

Deployed to ISAPI folder (_vti_bin)

Activate the features for the webpart:

Add the Web Part to the page:

The javascript needs a small modification - since the page in 2013 is loaded asynchronously.  But once I've re-attached the click event, the REST service itself works fine and returns the properties of the selected item.

The SharePoint Pinterest-style Image Library

/

A picture is worth a thousand words.

 

In the latest version of spaspa.codeplex.com, I created a separate Knockout Template and bind the Images library (BaseTemplateID 851) to it.  Then I inserted a simple jQuery Plugin Wookmark https://github.com/GBKS/Wookmark-jQuery

The end result is that when we have pictures, they are displayed in an awesome layout.

As an added bonus, I'm calculating the thumbnail image from SharePoint, so instead of rendering:

http://spg-dev-jl/PublishingImages/wallpaper_08.jpg

image

Original: 78K

I'm rendering

http://spg-dev-jl/PublishingImages/_w/wallpaper_08_jpg.jpg

image

Thumbnail image generated by SharePoint.  Which is a far smaller file - 16k.

 

Next update, I'll try to resolve those pesky SharePoint users and get the correct user name and picture.  So we don't have Mr. Bill Gates staring back at us! ;-)

Test your C#: Generic overloaded constructors

/

I love languages.  Here's one for a language nut.

public class Response<T> {

    private T result;
    private string error;

    public Response(T result) { this.result = result; }
    public Response(string message) { this.error = message; }

}

 

You can use this generic class as a wrapper for returning data.

return new Response<int>(1000);

Or to return an abnormal result

return new Response<int>("Something has gone wrong");

 

Question 1

The fun part then, is what happens when you have this?

var result = new Response<string>("Is this a result or an error?");

What is result

 

Question 2


What about this:

public class Sample
{
    public static Response<T> GetSample<T>(T arg)
    {
        return new Response<T>(arg);
    }
}

and then:

var result = Sample.GetSample("Is this an error?");

What is result
