Here’s another case where looking at my blog stats gave me an idea for a post. There were several searches about the apostrophe character which led people to my blog today:
- sharepoint data view apostrophe
- dataview apostrophe problem sharepoint
The apostrophe character (‘ or ' or ASCII character 39) is a bit of a trickster in Data View Web Parts (DVWPs). When you create a new DVWP, you’ll generally see that SharePoint Designer creates a parameter for the apostrophe for you:
This lets you use the $dvt_apos value where you might need an apostrophe, such as in concat(), contains(), etc. functions. In many cases, you will be able to use encoding for the apostrophe: ', but if that doesn’t seem to be working, try the $dvt_apos value instead. Once you get the hang of it, the apostrophe isn’t much of a problem (I usually delete the parameter just to keep my XSL clean), but it can be infuriating until you do catch on.
