Hallo,
die Mehrfachauswahl Felden sind in der Content Query WebPart(SharePoint 2007) nicht unterstützt. Schau mal bitte diesen Artikel hier: Inconvenient Content Query Web Part vs. Lookup fields with multiple values
Content Query Web Part has been around for a while now and has proven to be a great performing and a very flexible content aggregation solution. In spite of its power it has some shortcomings like for example lack of support for Lookup fields with multiple values.
This problem isn’t new and has been mentioned on the Microsoft Enterprise Content Management (ECM) Team Blog nearly three years ago: “SPSiteDataQuery and by extension the Content Query Web Part doesn’t support multi-value lookup fields”.
If you do want to use the Content Query Web Part and you do want to make this work, there are a couple approaches you might consider.
Custom Multi Lookup Field
One of the first things that could come to your mind might be developing a custom Lookup field which would allow selecting multiple values. Because the LookupMulti field type isn’t supported by the CQWP you could create a totally custom field type deriving from the Text or Note field type. The value of a Lookup field with multiple values is a ;# delimited string, such as id1;#value1;#id2;#value2 which can easily be converted to the SPFieldLookupValueCollection type so that you can work with the stored values in a way comparable to the standard LookupMulti field. You could even go a step further and provide a similar User Interface to the one the LookupMulti field has using the GroupedItemPicker control.
While this is definitely a plausible approach, many people find working with custom field types rather complex. There are quite a few different components you have to consider while creating a custom field type if you want to make it fool-proof. The worst of it all in my opinion is, that a custom field type is available in all Web Applications across the whole farm. In other words: after you deploy your custom field type everyone else is able to use it in their Web Applications as well.
Gruss,
Alex
