Issue with PowerShell variables

[sjacobs]

I just found out about Universal Dashboard yesterday, and I love it.
I may not be using it correctly, though. I have the following sample script:
Import-Module UniversalDashboard

Get-UDDashboard | Stop-UDDashboard

$services = Get-Content 'C:\temp\Services.txt'
$Dashboard = New-UDDashboard -Title "Service Groups" -Content {
    New-UDLayout -Columns 3 -Content {
        foreach ($service in $services) {
            New-UDCard -Title "$($service) services" -Content {
                $criteria = "$($service)*"
                New-UDElement -Tag "div" -Content {"$((Get-Service | ? displayname -like "$($service)*").Count) members in group"}
                New-UDButton -Text "Generate $($service) list" -OnClick {
                    Get-Service | ? displayname -like "$($service)*" |
                                Select Name, DisplayName, status | 
                                Export-Csv -Path c:\temp\outServices.txt -NoTypeInformation
                    Show-UDToast -message  "$($service) member list generated." -Position bottomRight -Duration 3000 
                }
            }
        }
    }
}
Start-UDDashboard -Dashboard $Dashboard -Port 10001

My services.txt file contains the following 3 lines:
Application
Diagnostic
Hyper-V

Here is a screenshot:

When I click on the UDButton, I would like to export the services beginning with the name on the card, and display a toast message. For some reason, $service is being ignored in both the button’s OnClick event and in the toast message.
Any assistance would be appreciated. Thanks!

Welcome to the UD forum and happy to have another UD lover.

I am not in front of a computer but I think the problem is the same as in this thread: Pass variable to modal

Thanks for the response. The thread seems to be saying that I need to add a UDEndpoint to pass a variable to the toast. I’ve tried the following, but the toast message does not appear:

Get-UDDashboard | Stop-UDDashboard

$Dashboard = New-UDDashboard -Title "Parameter Test" -Content {
            $service = "Test Service"
            New-UDCard -Title "$($service)" -Content {
                New-UDButton -Text "$($service) list" -OnClick {
                    New-UDEndpoint -Endpoint {
                        Show-UDToast -message  $ArgumentList[0]
                    } -ArgumentList @($service)
                } 
            } 
}
Start-UDDashboard -Dashboard $Dashboard -Port 10001

I think the problem is that you are using {} instead of () for -OnClick

Try this:

New-UDButton -Text "$($service) list" -OnClick (
                    New-UDEndpoint -Endpoint {
                        Show-UDToast -message  $ArgumentList[0]
                    } -ArgumentList @($service)
                )

Bingo! That was it! Thank you very much!!

Is there a way to mark the question as answered? Thanks again!

[augustin.ziegler]

Not that I am aware of … thought so too about this
