TreeDataGrid Quick Start Guide

Overview​

The Avalonia TreeDataGrid is a control 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

Installation​

See the Installation Guide for step-by-step instructions on how to install Accelerate components.

Add the TreeDataGrid package to your project:

dotnet add package Avalonia.Controls.TreeDataGrid

Add the License Key​

Include your Avalonia UI license key in the executable project file (.csproj):

<ItemGroup>
  <AvaloniaUILicenseKey Include="YOUR_LICENSE_KEY" />
</ItemGroup>

For multi-project solutions, you can store your license key in an environment variable or a shared props file to avoid duplication.
