Design paginated Reports
หมายเหตุ: บทความนี้ยังเป็นภาษาอังกฤษ เนื่องจากคำแปลภาษาไทยกำลังอยู่ระหว่างจัดทำ
Purpose
หัวข้อที่มีชื่อว่า “Purpose”Build PDF reports with validated data sources, page-aware bands, repeating child rows, and Freeform or Tablix layouts.
Report structure
หัวข้อที่มีชื่อว่า “Report structure”A Report selects one dataSource table, optional parameters, page settings, and bands. Page size is A4 or Letter; orientation is portrait or landscape; margins are [top, right, bottom, left] in points.
| Band | Behavior |
|---|---|
| Header | Renders on firstPage, everyPage, or lastPage. Space is reserved only on pages where it renders. |
| Detail | Repeats for each main data-source record. |
| Footer | Renders on firstPage, everyPage, or lastPage and stays inside the physical page. |
| Line source | Repeats related child records identified by table and refField after each main Detail. |
Legacy pageHeader and pageFooter metadata remains compatible and is normalized to Header/Footer with everyPage behavior in the Designer.
Choose a layout
หัวข้อที่มีชื่อว่า “Choose a layout”Freeform bands position text, field, image, line, and rectangle elements on a fixed canvas. A Freeform Detail or Line row is atomic: when its designed height does not fit, the whole row moves to the next page.
Tablix bands define columns with field, label, width, alignment, and format plus header/row styles and border settings. Set headerHeight and rowHeight deliberately; the renderer uses them to plan pages and repeats the Tablix header after a page break.
Switching a band between Freeform and Tablix removes the previous layout’s elements or columns. Confirm the warning only after exporting or copying any design that must be retained.
Procedure
หัวข้อที่มีชื่อว่า “Procedure”- Create a Report in Web Designer and select its App, Model, Layer, and source table.
- Choose page size, orientation, margins, and a default font.
- Configure Header/Footer display policy and height.
- Design the main Detail as Freeform or Tablix.
- Add each Line source, choose the child table and reference field, and design its repeating band.
- Add typed parameters and verify their bindings.
- Validate the Report JSON, save it, and generate PDFs with zero, one, and enough records to cross several pages.
Fonts and pagination checks
หัวข้อที่มีชื่อว่า “Fonts and pagination checks”Roboto and Noto Sans Thai are built in. PDF rendering segments mixed Thai and Latin text by grapheme and selects a font with the required glyphs. Installed report fonts can be used as defaults or per-element/Tablix overrides.
Test first-, middle-, and last-page Header/Footer policies; long Detail and Line sequences; Tablix page breaks; configured row heights; footer position; mixed Thai/Latin output; empty datasets; and both page orientations.
Security
หัวข้อที่มีชื่อว่า “Security”Grant the named Report through a Privilege and also grant read access to its data source. A visible menu item is not authorization; direct report requests are checked server-side.
