WPF Tips

2020/09/29 | 4 minute read |

I will start some post around WPF and PowerShell with XAML and I give you some Tips for your applications Today I start this series with Variables in your project. the First question is “How to find variables into your XAML files ?”

There is multiple ways, for example we start with the same XAML file.

</Controls:MetroWindow>

Load_assembly

1. The First way

I decided to use Mahapps theme for this Application, because it’s very easy to use with XAML and PowerShell.

The first way to find your WPF object in your form you need use this method : foreach WPF Controls you need to assign and create a variable for add event.

$CEIP = $Form.FindName("CEIP")
$Choose_Network = $Form.FindName("Choose_Network")
$Choose_Static = $Form.FindName("Choose_Static")
$DNS_Server = $Form.FindName("DNS_Server")
$Domain_Name = $Form.FindName("Domain_Name")
$Gateway = $Form.FindName("Gateway")
$Github = $Form.FindName("Github")
$IPAddress = $Form.FindName("IPAddress")
$MainPanel = $Form.FindName("MainPanel")
$Network_Mask = $Form.FindName("Network_Mask")
$NTP = $Form.FindName("NTP")
$Passwd_R = $Form.FindName("Passwd_R")
$Passwd_VCSA = $Form.FindName("Passwd_VCSA")
$Site_Name = $Form.FindName("Site_Name")
$SSH = $Form.FindName("SSH")

2. The second

The second way is very funny because you must just use two function to find in your form all WPF Controls with the atribute Name and create a Powershell variable with this rule $WPF_YourNameControls

$XamlMainWindow.SelectNodes("//*[@Name]") | %{
    try {Set-Variable -Name "$("WPF_"+$_.Name)" -Value $Form.FindName($_.Name) -ErrorAction Stop}
    catch{throw}
    }

This Powershell code Find all Controls in your XAML and create a powershell variable.

Function Get-FormVariables{
if ($global:ReadmeDisplay -ne $true){Write-host "If you need to reference this display again, run Get-FormVariables" -ForegroundColor Yellow;$global:ReadmeDisplay=$true}
write-host "Found the following interactable elements from our form" -ForegroundColor Cyan
get-variable *WPF*
}
Get-FormVariables

Here the result when you launch pour PowerShell script if you want to hide this outpout you need to comment this line like this…

#Get-FormVariables

3. How to try
