매개 변수

  The total number of pages.

• report
  The Report object being evaluated.

• pageReportItems
  A PageReportItems collection containing report items on the page.

• pageHeader
  The resulting page header, if it needed evaluation. If this is null, check the PageHeader.

• pageFooter
  The resulting page footer, if it needed evaluation. If this is null, check the PageFooter.

주의

The page header and footer of the report may include aggregates or other information that is dependent on the contents of that page of the report. If the NeedsHeaderFooterEvaluation property of the Report is true, the rendering extension needs to create a PageReportItems object and add all the report items that are completely contained on the page into the collection. The rendering extension then calls the EvaluateHeaderFooterExpressions function, passing in the collection, and the report server returns the new page header and page footer. If the header or footer didn’t need to be evaluated, then they were available directly on the Report object. In the case that the header needs to be evaluated but the footer doesn’t (or vice-versa), the header is available from the result of EvaluateHeaderFooterExpressions, while the footer is available directly in the object model.

All visible items and items that are always hidden in the page should be included in the collection of report items. Conditionally hidden items will not be included if they are currently hidden.
