In previous versions, the only way to specify unbound column values was to handle an event and write appropriate code. The same applied if you needed conditional formatting with complex criterias. With this new release, DevExpress WinForms controls now allow you to address both these requirements using an intuitive design-time editor.
An updated version of the DevExpress Expression Editor (the first version was introduced in XtraReports v2008 vol 2) is now available to our WinForms Grids controls. You can use it to specify formulas for unbound column value computation or to setup conditional formatting. The DevExpress Controls that support this new feature are the XtraGrid and XtraPivotGrid.
For unbound columns, you can also enable end-user expression customization. Simply enable an appropriate option and the column's header menu will include a link to the Expression Editor.
Beyond this, we've also extended the Expression Editor with approximately 50 new functions.
