Methods

BuildComponentCssVariables(Dictionary<string, string>)

Contributes additional CSS custom properties to the inline style attribute. Keys that collide with framework-owned --bob-inline-* variables will be overwritten.

public void BuildComponentCssVariables(Dictionary<string, string> cssVariables)

Parameters

cssVariables Dictionary<string, string>

BuildComponentDataAttributes(Dictionary<string, object>)

Contributes additional data- attributes to the root element. Keys that collide with framework-owned data-bob- attributes will be overwritten.

public void BuildComponentDataAttributes(Dictionary<string, object> dataAttributes)

Parameters

dataAttributes Dictionary<string, object>

BuildRenderTree(RenderTreeBuilder)

Renders the component to the supplied Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder.

protected override void BuildRenderTree(RenderTreeBuilder __builder)

Parameters

__builder RenderTreeBuilder

DisposeAsync()

Async disposal path. Blazor invokes this first when the component is unmounted because the type implements System.IAsyncDisposable; it tears down the JS-side behavior instance via BlazOrbit.Abstractions.BOBComponentPipeline.DisposeBehaviorAsync().

public override ValueTask DisposeAsync()

Returns

ValueTask

Remarks

Both this method and Dispose(bool) run on disposal — Blazor calls DisposeAsync for the async work and the framework's System.IDisposable contract still invokes Dispose(true) afterward. The split is intentional: async work (JS interop teardown) lives here, sync work (event unsubscribe) lives in Dispose(true). Both set IsDisposed so derived components can guard post-await continuations regardless of which path runs first.

TryParseValueFromString(string?, out TValue, out string?)

Parses a string to create an instance of TValue. Derived classes can override this to change how Microsoft.AspNetCore.Components.Forms.InputBase<TValue>.CurrentValueAsString interprets incoming values.

protected override bool TryParseValueFromString(string? value, out TValue result, out string? validationErrorMessage)

Parameters

value string

The string value to be parsed.

result TValue

An instance of TValue.

validationErrorMessage string

If the value could not be parsed, provides a validation error message.

Returns

bool

True if the value could be parsed; otherwise false.
