The WinUI TreeGrid, also known as a multicolumn tree view, is a data-oriented control that displays self-relational data in a tree structure UI. Its rich feature set includes editing with different column types; selection; data loaded on demand; and node selection with checkboxes, sorting, and filtering.

Data binding

  • Bind hierarchical data by specifying child mapping.
  • Display self-relational data in a tree structure by specifying the parent and child mappings.
  • Use the unbound mode, where the data is loaded on demand through events.

  • Utilize built-in column types such as text, date, and combo box.
  • Embed controls such as a progress bar and rating to view or edit data.
  • Commit or roll back changes when a data object implements IEditableObject.
