Make a Data View Web Part Work on Sub Sites

One of the things about SP 2010 that has driven me crazy is the inability to get DVWPs from one level of a site to work correctly in another level. Maybe you have a list on a subsite and want to surface that content on the homepage, or the list is at the root and you want to use the DVWP on a sub site. I even went as far as having my company pay for Laura Roger’s time a year or so ago to have a web meeting with her to see if there was a solution. What I was told was that there were a few things you can try but there was no guarantee any of it would work, depending on your specific farm setup, etc. I found some instructions on the web with hacks but they never went deep enough and I could never get them to work.

Last night, as I was thinking about another dvwp issue-how to create a dvwp that displays an item randomly-I found a site that had a solution for that issue as well as one for the other issue. The problem was that the instructions still were not clear enough, there were steps that maybe were assumed but that I didn’t know about or understand. So I had to poke it a while but I finally got both issues-the random item dvwp and the make dvwp work anywhere in the site- to work.

I take no credit for these solutions, I only translated them into a more visual language for folks like myself.

Styling webpart data with the Data View Web Part

One of the things that as been driving me crazy is the inability to selectively style webparts. On the home page of my company’s intranet, I have several webparts pulling content in, and they all look the same. I primarily wanted to make the announcements web part look different. I tried every hack I could think of to find some kind of unique hook to attach some styling to. I would change the title style and then watch it change ever title on the page. I have been trying to find uses for the data view web part and so I thought, maybe I can use that to pull in the announcements and then style them…

Long story short, it worked. Using the dvwp I was able to pull in the announcements list, set what fields to display, and then individually style the display of those fields.

First, I created a page layout. You can’t add the dvwp to pages directly unless you create a page based off a page layout and then detach that page from the page layout in SPD before you work on it. On the page layout in Sharepoint Designer, I selected a web part zone, clicked on Data View in the toolbar, and then selected Insert Data View. I then pulled the announcements list onto the dvwp area. I clicked on the arrow to the right of the DVWP and the Common Data View Tasks box displayed.

First, I edited the columns. I removed all but Title and Body. Then I changed the layout to Repeating Form Style. I then set the paging to display items in sets of 4. Under Sort and Groups, I set it to sort by Created, descending.

Now it was time to style the content. First, I removed the word Body that displayed right over the body content. Then I moved the title xsl code to right above the body code. I created two styles, one to handle the title and one for the body. I wrapped the styles around the fields and then cleaned up the display a bit by removing the extra row, hr and br tags.

Once that was done, I saved the layout, checked it in and then created a new page based off that layout. The dvwp displayed on the page as a webpart. I exported the webpart and then added it to the Web Part Gallery. I went to the intranet home page, put it in edit mode, and then added the webpart to the page.

One note, I tested this on my dev server first and made sure it worked before I tried it on production 😉
