Page Layout

PageLayout is used to define page-specific elements across application.

Title

Title is used to render page title in the PageHeader.

@inject PageLayout PageLayout

@{
    PageLayout.Title = "My Page Title";
}

MenuItemName

Indicates current selected menu item name. Menu item name should match a unique menu item name defined using the Navigation / Menu system. In this case, it is expected from the theme to make the menu item "active" in the main menu.

@inject PageLayout PageLayout

@code {
    protected override async Task OnInitializedAsync()
    {
        PageLayout.MenuItemName = "MyProjectName.Products";
    }
}

Menu item name can be set on runtime too.

@inject PageLayout PageLayout

<Button Clicked="SetCategoriesMenuAsSelected">Change Menu</Button>

@code{
    protected void SetCategoriesMenuAsSelected()
    {
        PageLayout.MenuItemName = "MyProjectName.Categories";
    }
}

Be aware, The Basic Theme currently doesn't support the selected menu item since it is not applicable to the top menu.

BreadCrumbs

BreadCrumbItems are used to render breadcrumbs in the PageHeader.

@inject PageLayout PageLayout

@{
    PageLayout.BreadcrumbItems.Add(new BlazoriseUI.BreadcrumbItem("My Page", "/my-page")); 
}

Toolbar

ToolbarItems are used to render action toolbar items in the PageHeader.

@{

}
