Report Conditional Rules determine if Report Content is displayed or not. Report Rules are XQuery expressions that return True or False and determine if Content is Enabled depending on the Report Data Source. Report Rules are useful for controlling the flow of Report Content.
To Add or Edit a Report Rule click on the Report Treeview and select the Rule Node.
Rules can be applied to all Report Items allowing flexible conditional control of Report Content. By Default if empty the Rule will always be True.
The Report Rule Content Type can be either a Literal or a File. If the Content Type is a File the Content for the Report Rule is read from the specified URI.
Report Rules can also contain Fields which can be used to substitute Content in the Report Query. XQuery and / or XSLT is used in Report Fields and provides the means to extract and manipulate data from a report data source.
XML namespaces are used for providing uniquely named elements and attributes. If the Data Source contains Namespaces they can be applied to the XQuery Processor.
