Toolbar and Context Menu
The FileManager component provides the following UI customization properties:
- The toolbar property specifies the toolbar's visibility and available commands.
- The contextMenu property specifies the context menu's availability and its commands.
The toolbar and context menu support context-invariant and context-sensitive items that can be visible or hidden depending on user action.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
