TreeView
Family: Navigation & Workflow
Namespace: Tessera.Controls
Use TreeView when this interaction is the best match for your screen workflow.
When to use
- You need a
TreeView-style interaction inside the navigation & workflow lane. - A titled widget surface improves scanability in dense shells.
- The control is mainly presentational or state-driven through property updates.
Minimal usage
csharp.cs
using Tessera.Controls;
using Tessera.Layout;
var widget = new TreeView
{
Title = "TreeView"
};
return Screen.Build(window => window.Body(body => body.Center(widget, width: 44, height: 9)));Common pitfalls
- Do not choose
TreeViewby name only; validate it against the target workflow. - Keep this control scoped to the navigation & workflow concern; avoid cross-layer state coupling.
- Set focused/normal styles intentionally so keyboard focus remains obvious.
- Keep disabled state explicit and reversible so users understand why actions are blocked.
