Blorc.Core

Blorc.Core is a set of components that can be used to write Blazor libraries and apps.

BlorcComponent

BlorcComponentBase is a base control for any Blazor component. It adds several new features to any component.

Property bags

Thanks to the underlying property bag, each component will automatically support change notifications.

[Parameter]
public bool IsGrouped
{
    get => GetPropertyValue<bool>(nameof(IsGrouped));
    set => SetPropertyValue(nameof(IsGrouped), value);
}

State converters

Because properties can be watched automatically via the property bag, it's possible to subscribe to properties and automatically update states based on property changes.

CreateConverter()
    .Fixed("pf-c-select")
    .If(() => IsExpanded, "pf-m-expanded")
    .Watch(() => IsExpanded)
    .Update(() => Class);

Feature	Description
Fixed	This is a fixed of constant expression that will always be added.
If	The state is added in case the predicate returns true (e.g. IsExpanded == true).
Watch	Adds a property to the watch list. The state will be re-evaluated every time a watched property changes.
Update	Updates a specific property with the new state. In the example above the Class property will be updated every time the IsExpanded property changes.

Binding system

To be described...

DocumentService / DOM manipulation

Blazor is able to update everything within the <app> element. Sometimes it's necessary to update the DOM outside this element. This is possible via the IDocumentService that uses Javascript interop:

@functions
{
    [Inject]
    public IDocumentService DocumentService { get; set; }

    protected override void OnInit()
    {
        base.OnInit();

        DocumentService.InjectHead(new Css("/patternfly/patternfly.css"));
    }
}
