Pages

Information about Universal App pages.

An app can consist of one or more pages. A page can have a particular name and URL. You can define a URL that accepts one or more variables in the URL to define a dynamic page.

Creating a new page

Within the app editor, expand the Pages navigation menu and click New Page.

You can edit a page by clicking the link in the menu. The code editor will switch to the page's content.

To reference the page in your dashboard, use Get-UDPage.

Basic Page

A basic page can be defined using the New-UDPage cmdlet. You could navigate to this page by visiting the /appURL of your dashboard.

$Pages = @()
$Pages += New-UDPage -Name 'Dashboard' -Content {
    New-UDTypography -Text 'Dashboard'
}

New-UDApp -Title 'Pages' -Pages $Pages

App with Multiple Pages

Apps can have multiple pages and those pages can be defined by passing an array of UDPages to New-UDApp

$Pages = @()
$Pages += New-UDPage -Name 'App One' -Content {
    New-UDTypography -Text 'App Two'
}

$Pages += New-UDPage -Name 'App Two' -Content {
    New-UDTypography -Text 'App Two'
}

New-UDApp -Title 'Pages' -Pages $Pages

You may want to organize your app into multiple PS1 files. You can do this using pages.

$UDScriptRoot = $PSScriptRoot
$Pages = @()
$Pages += New-UDPage -Name 'App One' -Content {
    . "$UDScriptRoot\db1.ps1"
}

$Pages += New-UDPage -Name 'App Two' -Content {
    . "$UDScriptRoot\db2.ps1"
}

New-UDApp -Title 'Pages' -Pages $Pages

Page with a Custom URL

A page can have a custom URL by using the -Url parameter. You could navigate to this page by visiting the /db URL of your app.

$Pages = @()
$Pages += New-UDPage -Name 'App' -Url '/db' -Content {
    New-UDTypography -Text 'App'
}

New-UDApp -Title 'Pages' -Pages $Pages

Page with Variables in URL

You can define a page with variables in the URL to create pages that adapt based on that URL.

$Pages = @()
$Pages += New-UDPage -Name 'Dashboard' -Url '/db/:user' -Content {
    New-UDTypography -Text 'Dashboard for user: $User'
}

New-UDApp -Title 'Pages' -Pages $Pages

Query string parameters

Query string parameters are passed to pages and other endpoints as a hashtable variable called $Query.

For example, if you visited a page with the following query string parameter: http://localhost:5000/dashboard/Page1?test=123

You would have access to this value using the following syntax:

$Query.test
$Query['test']

Role-Based Access

This feature requires a license.

You can prevent users from accessing pages based on their role by using the -Role parameter of pages. You can configure roles and role policies on the Security page.

$Pages = @()
$Pages += New-UDPage -Name 'Administrators' -Content {
    New-UDTypography -Text 'Dashboard for user: $User'
} -Role 'Administrator'

$Pages += New-UDPage -Name 'Operators' -Content {
    New-UDTypography -Text 'Dashboard for user: $User'
} -Role 'Operator'

New-UDApp -Title 'Pages' -Pages $Pages

Header

The following options are available for customizing the header.

Position

Use the -HeaderPosition parameter to adjust the behavior of the header.

• absolute\fixed - Remains at the top of the page, even when scrolling

• relative - Remains at the top of the page. Not visible when scrolling.

New-UDPage -HeaderPosition fixed -Content {
    New-UDElement -tag div -Attributes @{
        style = @{
            height = '150vh'
        }
    }
}

Colors

You can adjust the colors of the header by specifying the -HeaderColor and -HeaderBackgroundColor parameters. These colors will override the theme colors.

New-UDPage -Name 'Home' -Content {
} -HeaderColor 'black' -HeaderBackgroundColor 'white'

Navigation

You can customize the navigation of a page using the -Navigation and -NavigationLayout parameters. Navigation is defined using the List component. Navigation layouts are either permanent or temporary.

Custom Navigation

Custom navigation can be defined with a list. List items can include children to create drop down sections in the navigation.

$Navigation = @(
    New-UDListItem -Label "Home"
    New-UDListItem -Label "Getting Started" -Children {
        New-UDListItem -Label "Installation" -Href '/Installation' 
        New-UDListItem -Label "Usage" -Href '/Usage' 
        New-UDListItem -Label "FAQs" -Href '/faqs' 
        New-UDListItem -Label "System Requirements" -Href'/requirements' 
        New-UDListItem -Label "Purchasing" -Href '/purchasing' 
    }
)

$Pages = @()
$Pages += New-UDPage -Name 'Installation' -Content {
 New-UDTypography -Text "Installation"
}

$Pages += New-UDPage -Name 'Usage' -Content {
    New-UDTypography -Text "Usage"
} 

New-UDApp -Title "Hello, World!" -Pages $Pages -NavigationLayout permanent -Navigation $Navigation

Dynamic Navigation

Dynamic navigation can be used to execute scripts during page load to determine which navigation components to show based on variables like the user, IP address or roles.

You can generate dynamic navigation by using the -LoadNavigation parameter. The value of the parameter should be a script block to execute when loading the navigation.

$Navigation = {
    New-UDListItem -Label "Home - $(Get-Date)"
    New-UDListItem -Label "Getting Started" -Children {
        New-UDListItem -Label "Installation" -Href '/installation' 
        New-UDListItem -Label "Usage" -Href '/usage' 
        New-UDListItem -Label "FAQs" -Href '/faqs' 
        New-UDListItem -Label "System Requirements" -Href'/requirements' 
        New-UDListItem -Label "Purchasing" -Href '/purchasing' 
    }
}

$Pages = @()
$Pages += New-UDPage -Name 'Test' -Content {
 New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation

$Pages += New-UDPage -Name 'Test2' -Content {
    New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation


New-UDApp -Title "Hello, World!" -Pages $Pages

Role-Based Access

You can use dynamic navigation to create a navigation menu that takes advantage of roles. Use Protect-UDSection to limit who has access to particular menu items. Ensure that you also include the same role on the page.

$Navigation = {
    New-UDListItem -Label "Home" -Href '/Home' 
    Protect-UDSection -Role "Administrator" -Content {
        New-UDListItem -Label "Admins" -Href '/Admins' 
    }
}

$Pages = @()
$Pages += New-UDPage -Name 'Home' -Content {
 New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation

$Pages += New-UDPage -Name 'Admins' -Content {
    New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation -Roles "Administrator"

New-UDApp -Title "Hello, World!" -Pages $Pages

Layouts

The permanent layout creates a static navigation drawer on the left hand side of the page. It cannot be hidden by the user.

$Pages = @()
$Pages += New-UDPage -Name 'Test' -Content {
 New-UDTypography -Text "Hello"
} -NavigationLayout permanent

$Pages += New-UDPage -Name 'Test2' -Content {
    New-UDTypography -Text "Hello"
} -NavigationLayout permanent


New-UDApp -Title "Hello, World!" -Pages $Pages

The temporary layout creates a navigation drawer that can be opened using a hamburger menu found in the top left corner. This is the default setting.

$Pages = @()
$Pages += New-UDPage -Name 'Test' -Content {
 New-UDTypography -Text "Hello"
} -NavigationLayout temporary

$Pages += New-UDPage -Name 'Test2' -Content {
    New-UDTypography -Text "Hello"
} -NavigationLayout temporary


New-UDApp -Title "Hello, World!" -Pages $Pages

Horizontal Navigation

You can use New-UDAppBar with a blank page to create horizontal navigation.

New-UDApp -Title 'PowerShell Universal' -Pages @(
    New-UDPage -Name 'Page' -Content {
        New-UDAppBar -Children {
            New-UDTypography -Text "Title" -Variant h4 -Style @{
                marginRight = "50px"
            }
            New-UDMenu -Variant text -Text "Settings" -Children {
                New-UDMenuItem -Text 'Item 1' -OnClick { Invoke-UDRedirect "/item1" }
                New-UDMenuItem -Text 'Item 2' -OnClick { Invoke-UDRedirect "/item1" }
                New-UDMenuItem -Text 'Item 3' -OnClick { Invoke-UDRedirect "/item1" }
            }
            New-UDMenu -Variant text -Text "Options" -Children {
                New-UDMenuItem -Text 'Item 1' -OnClick { Invoke-UDRedirect "/item1" }
                New-UDMenuItem -Text 'Item 2' -OnClick { Invoke-UDRedirect "/item1" }
                New-UDMenuItem -Text 'Item 3' -OnClick { Invoke-UDRedirect "/item1" }
            }
            New-UDMenu -Variant text -Text "Tools" -Children {
                New-UDMenuItem -Text 'Item 1' -OnClick { Invoke-UDRedirect "/item1" }
                New-UDMenuItem -Text 'Item 2' -OnClick { Invoke-UDRedirect "/item1" }
                New-UDMenuItem -Text 'Item 3' -OnClick { Invoke-UDRedirect "/item1" }
            }
        } -DisableThemeToggle
    } -Blank
) 

Logo

You can display a logo in the navigation bar by using the -Logo parameter.

First, setup a published folder to host your logo.

Now, when creating your page, you can specify the path to the logo.

New-UDPage -Name 'Home' -Logo '/assets/favicon.png' -Content {
}

The logo will display in the top left corner.

To customize the style of your logo, you can use a cascading style sheet and target the ud-logo element ID.

Header Content

You can define custom content to include in the header by using the -HeaderContent parameter.

$Page = New-UDPage -Name 'Home' -Content {

} -HeaderContent {
    New-UDButton -Icon (New-UDIcon -Icon Users) -Text 'User'
}

New-UDApp -Title "Dashboard" -Pages $Page

Dynamic Page Title

Page titles are static by default, but you can override this behavior by using -LoadTitle. It will be called when the page is loaded. This is useful when defining pages in multilingual dashboards.

New-UDPage -Name "Home" -LoadTitle { "Current Time" + (Get-Date) } -Content { } 

Static Pages

Static pages allow for better performance by not executing PowerShell to load the content of the page. This can be useful when displaying data that does not require dynamic PowerShell execution. The page content is constructed when the dashboard is started.

New-UDPage -Name 'Static Page' -Content {
    New-UDTypography (Get-Date)
} -Static

Static pages do not have access to user specific data. This includes variables such as:

• $Headers

• $User

• $Roles

You can still include dynamic regions within pages. These dynamic regions will have access to user data. Reloading the below example will update the date and time listed in the page.

New-UDPage -Name 'Static Page' -Content {
   New-UDDynamic -Content {
       New-UDTypography (Get-Date)
   }
} -Static
