Bringing Map functionality into SharePoint 2010: Rendering Map List View

Overview

SharePoint 2013 introduces functionality to integrate location information and maps in SharePoint lists and location-based web and mobile apps for SharePoint with the following capabilities:

  • new field type named Geolocation that enables you to annotate SharePoint lists with location information. The built-in Geolocation field can render only with Bing Maps. However, you can create a custom field by using the Geolocation field as a parent field type, for example see my blog post about using Google Maps as map service.
  • Map View that displays a map (with data obtained from the Bing Maps service), using longitude and latitude entries from the Geolocation field type

Client-side rendering for Map List View in SharePoint 2013

Regarding Map View, SharePoint 2013 utilizes client side rendering framework for List View that allows to define the rendering logic of SharePoint list views using HTML/JavaScript. There is already predefined rendering template in SharePoint 2013  for Binq Maps service that is used when Map View is created, for more details see Create a map view for the Geolocation field in SharePoint 2013.

Map List View in SharePoint 2010

But what about SharePoint 2010? Let’s discuss one approach related with customizing List View for  XSLTListViewWebPart (XLV) . So, in proposed solution  geographical locations are stored in Custom List and custom View is used to render data on Map using Google Maps service For example, list items GeoMapDefaultView

will be represented in Map View as shown below

GeoMapView

Implementation of Map List View in SharePoint 2010

As was noted earlier for storing geographical location on a map and visualizing it in Map View we will define Custom List named GeoMap List.

GeoMap Content Type

For storing geographical locations we define the following Content Type

GeoMap List

GeoMap List is based on Generic List with GeoMap Content Type and with custom View

Customize the rendering of a List View in Sharepoint 2010: Displaying List Items in Accordion

Overview

The creation of non standard presentations for Lists/Libraries  is a fairly common  scenario and using the XSLT List View Web Part (XLV) possibilities that can be achieved pretty easily.
Let’s take a look how to render list of question and answers using Accordion Menu in SharePoint. Actually the idea for this post appeared after posting  of corresponding question on StackOverflow.
So, let’s discuss how it could be accomplished using XLV. For Accordion we will utilize jQuery UI library.

Accordion

Implementation

FAQ Custom List

First of all, let us define where  the questions and answers (FAQ) we’ll be stored. For this we will use Custom List with Content Type.

Custom View for arranging items using jQuery UI Accordion

After creating Custom List we add new View for displaying Accordion for FAQ items

XSLT style sheet for rendering Accordion View

XSLT style sheet for FAQ List is intended for the following purposes:

  • loading jQuery Core and UI Libraries
  • rendering list items using layout as specified for Accordion menu
  • initializing and rendering Accordion for List items

Using jQuery UI Accordion

jQuery Core and UI libraries are injected during XSLT style sheet processing. After JavaScript files which hosted on Microsoft CDN are loaded, jQuery UI Accordion is initialized for items.

FAQ List Accordion View rendered in XLV is shown below on picture

Embedding and Sharing Video in SharePoint. Part Two: Posting embedded code, support for different Video Providers, Preview view

Introduction

In previous post we have discussed  approach on how to embed video into SharePoint from YouTube. Custom List Video Links were used for storing embedded video properties and Computed Field for rendering Video player.
This time we will extend our solution with the following capabilities:

  • Support for different video providers listed in  oEmbed
  • Preview view for displaying video arranged in list
  • Alternative mode for posting the embed code for video into SharePoint

Support for different video providers

In addition to embed code using iframe, another options also available now. Some providers listed in oEmbed specification use object element for embedding code.

Table 1. Support for Video Providers listed in oEmbed specification

Provider Name Embedded Mode
YouTube IFrame, Object(YouTube)
Viddler –
Qik Object(Qik)
Revision3 IFrame
Hulu IFrame
Vimeo IFrame
CollegeHumor Object(CollegeHumor)
Jest Object(Jest)
CircuitLab –

Alternative mode for posting embedded code

Additionally to existing mode for embedding video code, the approach described below allows to paste the embed code as it was generated by Provider. Let’s take a look at the common usage scenario:

  • Generate and copy the embed code on the Provider website
  • Select Embed Code from New Item for Video Links List

  • In New Form for Video Links List paste the embed code and fill in comments if needed as shown below

For displaying video player the same (see previous post for details) Computed Field EmbeddedVideoOnForm field is used

Preview view for displaying video

In addition to default view (video player items with details), Preview view is intended to display items arranged by columns as shown below

Implementation

To paste the embed code we define Embed Code Content Type

where field EmbedCode for storing the embed code  is used

As was noted earlier, for displaying video player the same (see previous post for details) Computed Field EmbeddedVideoOnForm field is used, below is presented complete XSLT style sheet for  rendering of a field on a List View
