CAML Help

Collaborative Application Markup Language (CAML), based on XML language, is used in defining sites and lists, including fields, views, or forms in Microsoft� Windows� SharePoint� Services. For more information on CAML, see the MSDN article Introduction to Collaborative Application Markup Language (CAML).

CAML can be used in a number of ways, but in the Bamboo List Rollup Web Part, it is mainly used for defining front-end list or view definitions. For example, when selecting lists or views to include in a List Rollup, you may want to filter the list or view for use in a List Rollup data view. Some examples for implementing a CAML filter are as follows:

� To filter a list or view so users only see data where Status is equal to �Not Started�, type the following:

<Where>
    <Eq>
        <FieldRef Name='Status' />
        <Value Type='Choice'>Not Started</Value>
    </Eq>
</Where>

� To filter a list or view so users only see data where Priority is equal to �High� and Status does not equal �Completed�, type the following:

<Where>
    <And>
        <Eq>
            <FieldRef Name='Priority' />
            <Value Type='Choice'>(1) High</Value>
        </Eq>
    <Neq>
        <FieldRef Name='Status' />
        <Value Type='Choice'>Completed</Value>
    </Neq>
    </And>
</Where>

To download and install a free tool that enables you to build CAML filters quickly and easily, go to U2U CAML Query Builder for SharePoint 2007.

Applying a CAML filter to a list or view is entirely optional. You can always filter the list or view in SharePoint to suit your needs prior to including it in the List Rollup data view.
