Avalonia TreeDataGrid

Introduction

TreeDataGrid is a control for the Avalonia UI framework which displays hierarchical and tabular data together in a single view. It is a combination of a TreeView and DataGrid control.

The control has two modes of operation:

• Hierarchical: data is displayed in a tree with optional columns
• Flat: data is displayed in a 2D table, similar to other DataGrid controls

An example of TreeDataGrid displaying hierarchical data:
