This sample demonstrates the column chooser functionality in Tree Grid. Click the column chooser icon in the toolbar to open the column chooser and select columns to hide or show from the checkbox list.
The column chooser allows showing or hiding Tree Grid columns dynamically, and it is enabled by setting the ShowColumnChooser property to true. Columns can also be excluded from appearing in the column chooser by setting the ShowInColumnChooser property of the TreeGridColumn component to false.
In this demo, the column chooser is accessed through the toolbar and displays a list of columns with checkboxes for visibility toggling. The "Description" column is excluded from the chooser by setting its ShowInColumnChooser property to false.
More information about the column chooser can be found in this documentation section.
