How can i send click action to a Grid cell ? there is no ClickCellR method under my object

Anyone can help? Thanks!

Grids are different than tables and such within TestComplete.  They take a different approach to work with.

Fortunately, those folks at SmartBear already know this and have documented a lot of information on how to work with such grids... even the specific grid you're working with. :)

See https://support.smartbear.com/testcomplete/docs/app-objects/specific-tasks/grids/devexpress-xtragrid/index.html

Hope this helps!
