WinForms Expression Editor for DevExpress Grid Controls

Thinking Out Loud
14 July 2009

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.

This is really cool. I'm sure power users will love using that feature.

Very useful. Are these settings persisted in a saved layout? Would be great, if the end-user could add expression columns with this.

Looks good. It would be really great if you exposed the expression tree as an object model and then developers could create their own filters, sql statements, linq queries... Something I would find really useful.

We're just about to release v2009.2 and it would be a good idea to have an "accumulator"
