Reporting — Video Tutorial, Enhancements, Documentation Updates, Tips & Tricks (November 2021)

New DevExpress Reporting Video Tutorial

A Few Recent Enhancements of Note

RDLC and Crystal Reports Conversion Tool Supports New Expression Functions

As of last month, our Report Conversion Tool recognizes the following third-party expressions: RDLC’s Right and Mid functions, Crystal’s Length & Mid functions, and Crystal’s CurrentDate special field.

XRChart - RTL Support

Our XRChart control is now RTL-enabled! XRChart maintains right-to-left orientation if its parent container is placed into RTL mode (default behavior), or if the chart’s RightToLeft property is set explicitly.

New PDF Content Demo (Desktop and Web)

Check out the following demos if you want to embed a PDF file directly into your report:

• End-User Report Designer for WinForms - Embedded PDF Content
  **(must install our v21.2 WinForms Demo collection to proceed).
• End-User Report Designer for Web - Embedded PDF Content.

DirectX WinForms Demo

Our WinForms Reporting demos (within the DevExpress Demo Center) now include a DirectX | GDI+ switch. If you have yet to explore the benefits of DirectX rendering on the WinForms platform (a DevExpress exclusive), be sure to specify DirectX mode before you execute our report demos (DirectX improves glyph rendering quality and scrolling performance).

• How to Hide the Main Menu on a Print Preview Form

  Use one of the following options:

• Export to DOCX - Picture Box is Displayed in Front of a Label and Overlaps Text
