Excel-inspired Conditional Formatting

Deliver an experience familiar to everyone.

With our WinForms Conditional Formatting engine, your app can easily highlight cells or nodes based on specified criteria without writing a single line of code. Cells and nodes can be highlighted using animated data bars, icons, and predefined color scales. Users can easily apply/customize style conditions via the tree list's popup menu.

And of course, you can take advantage of predefined format rules or create custom rules as needed. The TreeList ships with both a design-time and runtime Conditional Formatting Rule Editor - so you and your users can create, edit, and delete format rules as and when needed.
