Class TwTreeList

Namespace
TwBlazor.Components
Assembly
TwBlazor.dll

Root of a tree of expandable/selectable items: renders the outer <ul role="tree"> and hosts nested TwTreeListItem nodes, given as ChildContent - typically generated with your own @foreach over whatever data you already have.

public class TwTreeList : TwBlazorComponentBase, IComponent, IHandleEvent, IHandleAfterRender, ITwComponent

Remarks

Every TwTreeListItem in the tree - regardless of nesting depth - cascades a reference to this root instance, so a checkbox toggle anywhere can call back into TwBlazor.Components.TwTreeList.NotifyDescendantChangedAsync to re-render the whole tree (needed for ancestors to reflect an indeterminate state once their descendants disagree).

Constructors

public TwTreeList()

Properties

ChildContent

Gets or sets the root-level TwTreeListItem nodes.

[Parameter]
public RenderFragment? ChildContent { get; set; }

Property Value

RenderFragment

HideIcons

Gets or sets whether each node's leading icon is hidden. Icons are shown by default - a folder for a node with children, a generic file icon for a leaf - unless a node's own Icon overrides it.

[Parameter]
public bool HideIcons { get; set; }

Property Value

bool

ShowCheckboxes

Gets or sets whether a checkbox is rendered next to each node. Checking or unchecking a node cascades to all of its descendants; a parent whose descendants disagree renders indeterminate.

[Parameter]
public bool ShowCheckboxes { get; set; }

Property Value

bool

Methods
