Dynamic Regions

Dynamic regions allow you control the reload of data within the region.

New-UDDynamic allows you to define a dynamic region. Pages themselves are dynamic in nature. This means that every time a page is loaded, it runs the PowerShell for that page. Sometimes, you may want to reload a section of a page rather than the whole page itself. This is when you will want to use dynamic regions.

Basic Dynamic Region

This dynamic region reloads when the button is clicked.

New-UDDashboard -Title "Hello, World!" -Content {
    New-UDDynamic -Id 'date' -Content {
        New-UDTypography -Text "$(Get-Date)"
    }

    New-UDButton -Text 'Reload Date' -OnClick { Sync-UDElement -Id 'date' }
}

Arguments List

An array of arguments may be passed to the dynamic region.

Note that the arguments are static and do not change when Sync-UDElement is invoked.

New-UDDynamic -Id 'dynamic_01' -Content {
                New-UDTypography -Text "This is an $($ArgumentList[0])
                 an $($ArgumentList[1]) in a UDDynamic"
                 } -ArgumentList @('example of', 'arguments list')

Auto Refresh

Dynamic regions enable the ability to auto refresh components after a certain amount of time. The entire region's script block will be run when autorefreshing.

If you have multiple related components that use the same data, consider putting them in the same dynamic region to improve performance.

    New-UDDynamic -Id 'date' -Content {
        New-UDTypography -Text "$(Get-Date)" -Variant h3
        New-UDTypography -Text "$(Get-Random)" -Variant h3
    } -AutoRefresh -AutoRefreshInterval 1

Loading Component

Sometimes refreshing a dynamic component may take some time. For example, if you are querying another service's REST API or a data. Dynamic regions support configuration of the component that shows when the region is reloading. By default, nothing is shown. This can be any Universal Dashboard component.

    New-UDDynamic -Content {
        Start-Sleep -Seconds 3
        New-UDTypography -Text "Done!"
    } -LoadingComponent {
        New-UDProgress -Circular
    }
