If I specify multiple parameters for a DVWP, I seem to have to always provide a value in the query string or I get nothing. For example,


How would I specify "everything from waldo and not limited to books" presuming that I must provide the 'category' parameter in the URL (which seems to be true for this web part)? One would presume something like * should work but it doesn't.

There is a field for "default value" but the question still applies: how to specify any, or all, or don't care.


You'll need a compound filter condition, something like this:

<xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row[@Category = $Category or $Category = '*']"/>


$Category is the parameter you've set up for the category Query String value

This way, if you pass an asterisk '*' for category, you'll get all categories.




...should work.

But the question comes in with how that's passed to the query.

Can you post the SharePoint:SoapDataSource tag here for troubleshooting?

  • Will look for SoapDataSource, but for now with 'fair' and 'appt' specified within the DVWP, .../ReviewResume5.aspx?fair=something&appt=student returns a row .../ReviewResume5.aspx?fair=''&appt='' and .../ReviewResume5.aspx?fair=""&appt="" return nothing. – Michael Broschat Jan 5 '11 at 12:55
  • The '*' will only work as a string value, not in any sort of wildcard way. – Marc D Anderson Jan 5 '11 at 14:34
