Using builtin variables in pages

Using builtin variables in pages

avatar
(anonymous user)

In Powershell Universal (v4), we have built pages with forms that asks users for input and then using these to automate stuff.
I have found that these pages are defined as .xml files in the file system, but we would (for example) like to pre-populate a textbox with the user email or username, using the builtin variable $UAJob.Identity.Name. As I understand it, we can’t use this in the xml file?
If not, how do we define a more dynamic page? I have seen references to cmdlets like New-UDPage, but not sure where to put these so that they show up in Powershell Universal?

Manually create a page using New-UDPage.

e.g.

New-UDPage -Blank -Name "TestPage" -Title "My Test Page" -HideNavigation -id "TestPage"  -Content {
      #My UD commands here...
}


Which ever page is your main home page add the -DefaultHomePage parameter to that pages New-UDPage cmdlet:

New-UDPage -Name "Home" -Blank -DefaultHomePage -Title "My app" -id "HomePage"  -Content {
   #my homepage here
}


Store these pages in a file in a folder somewhere in your app.

In your main dashboard.app file where you have your New-UDApp cmdlet load your pages into memory:

 $pages = @(
        # Load a folder of pages
        Get-ChildItem '/root/.PowerShellUniversal/Repository/dashboards/myapp/myPages*.ps1' -Recurse -File | ForEach-Object {
            & $_.FullName
        }
       # Load a page
        & '/root/.PowerShellUniversal/Repository/dashboards/myapp/home.ps1'


in your new-udapp cmdlet you will then need to declare you pages using the -Pages parameter:

New-UDApp -Title "My App"  -Pages $pages


Hope this helps

I’ve seen those code snippets before, but where to put them? In PowerShell Universal / User Interfaces / Pages, I have a few pages, defined by xml-files located in %programdata%\UniversalAUtomation\Repository\Pages. These are not relevant here as I understand it.
I have also created an app (PowerShell Universal / User Interfaces / Apps), but code for creating for example a Form does not work, generates an error rendering dashboard in PSU. Neither does the New_UDPage examples above. But is Apps not where I’m supposed to put the code?

Apologies, just seen this post.

The New-UDPage commands can go in separate ps1 files

The $pages scriptblook and New-UDApp command go in your main dashboard/app file in that order.
