Redirect in SharePoint Using Meta vs JavaScript

This morning I was working on a custom list item display form for a “Tags” list that I created in SharePoint (DispFormCustom.aspx). I replaced the standard display form web part with a data view web part (DVWP). For various reasons that I won’t bother explaining in this post, I needed to create a redirect on this page that included an additional tags parameter in the query string with the @Title of the current list item. For example, if a list item has an ID of “1” and a title of “jquery,” I want the page to redirect from http://server/lists/tags/dispformcustom.aspx?ID=1 to http://server/lists/tags/dispformcustom.aspx?ID=1&tags=jquery.

I didn’t want to use <meta http-equiv="refresh" content="0;url=/{@FileDirRef}/dispformcustom.aspx?ID={@ID}&tags={@Title}" /> because it creates a history entry in the browser. If the user clicks the Back button from the new page, they’ll go back to the page with the redirect and be immediately redirected to the page they were just on. This is bad for the UX. I could extend the time from 0 seconds to 3 seconds or more to give the user more time to click the Back button again, but I don’t think this is a good UX either. I want the redirect to be as transparent as possible. (more…)

Display Events from a SharePoint Calendar Using jQuery and FullCalendar

As part of a large department site redesign project, I wanted to implement a better calendar solution than what MOSS 2007 gives you OOTB. I remembered coming across the FullCalendar jQuery plugin a while back, so I decided to try using it with the calendar on my department’s site. I haven’t tested this in SharePoint 2010, but it should work just fine regardless of the version (just verify all of the column references in case any of them are named differently).

Prepping the Resources

I downloaded the latest FullCalendar package, unzipped the file, and uploaded the CSS and JavaScript files to a document library on my site. I like to use a library called WebResources and add a choice column with options for “CSS,” “Image,” “JavaScript,” and “jQuery” so I can keep track of all of my various resources in one place, with versioning.

I keep all of my resources in a "WebResources" document library grouped by the type of resource.

Once the files were uploaded, I copied the calendar.aspx page and renamed it CalendarCustom.aspx in SharePoint Designer (SPD). Then I switched back to the web UI, went to the calendar settings, and modified the duplicate “Calendar” view so I could rename it and set it as the default (this is the view that will contain our custom calendar). Next I opened that view and hid the default list view web part for the calendar.

The last step in prepping the page was to open it in SPD and add references to the CSS and JavaScript files that the calendar will need just below the <asp:Content ContentPlaceHolderId="PlaceHolderMain" runat="server"> tag on the page (you could also put them in a Content Editor Web Part):

Load the CSS and JavaScript references on the page. This can be done in a Content Editor Web Part, but I prefer to add them in the PlaceHolderMain section.

Setting Up the Data View Web Part

To make this happen, I used a Data View Web Part (DVWP) to output the necessary JavaScript for the plugin to generate the calendar. I selected the web part zone and inserted a new DVWP. I chose the Calendar list as my data source, selected the Title field and inserted it as a “Multiple Item View.”

Insert a DVWP with the calendar as the data source, and insert the Title field as a "Multiple Item View."

I didn’t want to bog down the browser by loading hundreds of really old events, so I set a filter on the DVWP so that only events with a start time greater than or equal to today minus 90 days would be displayed (see this post for more information on setting up CAML query offsets). This allows people to view events up to three months in the past, as well as current and future events. I also sorted the events by start time in ascending order.


Load SharePoint Web-optimized Images into a DVWP

It finally happened. I’m starting a SharePoint category on my blog.

So, I recently worked on a project in which users were encouraged to upload photos that they took at volunteer events around the country. The stakeholder wanted to have a slideshow of these images on the event home page, and of course it had to look good.

I immediately thought of using a Data View Web Part and some jQuery because I knew I could create a nice-looking slideshow using one of the many jQuery plugins available on the web. However, I wanted to make sure the images looked good and fit within the slide show’s boundaries.

Luckily for me SharePoint creates web-optimized and thumbnail versions of images when they are uploaded into a Picture Library (not to be confused with the standard “Images” document library that is created for a site with the Publishing feature enabled). The tricky part was getting those optimized versions to load on the page instead of the original images, some of which were small, and some of which were many megapixels in size. Fortunately most of the leg work for this project was already done thanks to this post on the blog.
