XAML with every attribute

Namespace xmlns:nv="http://nuvyntralabs.com/uikit". Kit attributes first, then inherited MAUI VisualElement / View members. Framework properties are the same on every NV* view and are not repeated in the official control reference.

xmlns:nv="http://nuvyntralabs.com/uikit"

<nv:NVTreeDataGrid
    Columns="{Binding Columns}"
    Rows="{Binding Rows}"
    Filter="Filter"
    SortKey="none"
    SortDirection="none"
    PageSize="0"
    PageIndex="0"
    FrozenColumnCount="0"
    VisibleRows="VisibleRows"
    Roots="{Binding Roots}"
    IsVisible="True"
    IsEnabled="True"
    Margin="0"
    HorizontalOptions="Fill"
    VerticalOptions="Fill"
    BindingContext="{Binding}" />

Attributes

custom names are Lumina API. Unmarked names match familiar MAUI / forms usage.

Attribute	Type	Default	Kind	Explanation
`Columns`	`IList`	—	custom	`Header`, `Binding`, `Key` alias, `Sortable`, `Frozen`
`Rows`	`IList<IDictionary<string, object?>>`	—	custom	Grid row dictionaries keyed by column Binding / Key.
`Filter`	`string`	`""`	familiar	`""` case-insensitive cell match
`SortKey`	`string`	`none`	familiar	none header tap cycles none → asc → desc
`SortDirection`	`NVSortDirection`	`none`	familiar	none header tap cycles none → asc → desc
`PageSize`	`int`	`0`	familiar	`0` / `0` `0` page size shows all; pager when `> 0`
`PageIndex`	`int`	`0`	familiar	`0` / `0` `0` page size shows all; pager when `> 0`
`FrozenColumnCount`	`int`	`0`	familiar	`0` plus per-column `Frozen`
`VisibleRows`	`computed`	—	familiar	filtered / sorted / paged
`Roots`	`IList`	—	familiar	flatten + `Expand` once

Inherited MAUI attributes

Every NV* view also inherits MAUI ContentView / VisualElement members. Those are framework properties.

Attribute	Type	Default	Explanation
`IsVisible`	`bool`	`true`	MAUI `VisualElement`. Hide the control without removing it from the tree.
`IsEnabled`	`bool`	`true`	MAUI `VisualElement`. When false, the control ignores input and uses the Disabled visual state.
`Margin`	`Thickness`	`0`	MAUI `View`. Outer gap around the control. Use `NVTokens.Space*` for Lumina rhythm.
`HorizontalOptions`	`LayoutOptions`	`Fill`	MAUI `View`. Horizontal alignment in the parent (`Start`, `Center`, `End`, `Fill`).
`VerticalOptions`	`LayoutOptions`	`Fill`	MAUI `View`. Vertical alignment in the parent.
`BindingContext`	`object?`	inherited	MAUI `BindableObject`. Source for `{Binding …}` paths on this subtree.

Typical usage
