TreeDataGridWeb.Blazor 0.2.0

TreeDataGridWeb.Blazor

Install TreeDataGridWeb.Blazor version 0.2.0. The package targets .NET 8/.NET 10 and bundles the real Core/Web engine and styles as local static web assets for interactive WebAssembly and Server.

Typed grid and binding

@using TreeDataGridWeb.Blazor
<TreeDataGrid TItem="Row" Items="rows" ItemsChanged="Changed" Columns="columns"
              SelectedPaths="selected" SelectedPathsChanged="SelectionChanged" />
@code {
    public sealed record Row(string Name, int Value);
    private Row[] rows = [new("First", 1), new("Second", 2)];
    private GridColumn[] columns = [new("Name", "name", "2*", true), new("Value", "value", "*", true)];
    private IReadOnlyList<string> selected = [];
    private void Changed(Row[] value) => rows = value;
    private void SelectionChanged(IReadOnlyList<string> value) => selected = value;
}

Column property names match serialized JSON casing. ChildrenProperty enables hierarchy. CellChanged exposes a typed item, model path, column and old/new values. ItemsChanged retrieves the full native DTO collection through streaming. SelectedPaths uses model paths such as 0 and 0.1; paths are not visual row indexes. ItemsRevision explicitly signals in-place source updates. Parent acknowledgements of native edits do not replace an unchanged native source.

GetItemsAsync, SetCellValueAsync, SelectPathsAsync, BeginEditAsync, CommitEditAsync, search, scrolling, CSV and view-state methods are available after Ready. Model accepts a caller-owned Core source for advanced use. Native sources and callbacks remain accessible through Module.

Razor cells

GridColumn.Template accepts BrowserFunction.RazorTemplate(id) backed by BrowserTemplate<TItem>. Register AddTreeDataGridWebBlazor and the host's RegisterTreeDataGridWebBlazor method first. The sample executes a Razor callback inside a native virtualized cell and verifies a native edit updates typed C# items.

An optional EditTemplate uses the same factory mechanism; its editor must provide an input marked data-grid-value. Keep durable edit state outside virtualized roots. Browser factories can also supply create/update/dispose hooks.

Read INTEGRATION.md for hosting, callback timing, reference ownership, streaming and releases. The wrapper preserves the underlying engine's compatibility boundaries and does not claim a generated C# replacement for every desktop API.
