Question

I am using the below code in PoweerShell script:-

$options = @{
    "A"="a"
    "B"="b"
}

$props = @{
    Parameters = @(
        @{Name="selectedOption"; Title="Choose an option"; Options=$options; Tooltip="Choose one."}
    )
    Title = "Option selector"
    Description = "Choose the right option."

    Height = 300
    ShowHints = $true
}

Read-Variable @props

I need to get selected dropdown values. However, it is showing ok or cancel result when I click on ok and cancel button in dialog box. I have tried $props.Parameters.Value as well it is showing the dropdown values but not the selected value everytime.

Answer 1

You should check $selectedOption value after you execute the script.

That's were the value of what user selected is stored.

Your parameters contain:

{Name="selectedOption"; Title="Choose an option"; Options=$options; Tooltip="Choose one."}

Look at the part Name="selectedOption". That means that your value will be stored in $selectedOption variable.

And you should only process if $result returns ok, like that:

$options = @{ "A"="a" "B"="b" }

$props = @{
    Parameters = @(
        @{Name="selectedOption"; Title="Choose an option"; Options=$options; Tooltip="Choose one."}
    )
    Title = "Option selector"
    Description = "Choose the right option."
    Width = 300
    Height = 300
    ShowHints = $true
}

$result = Read-Variable @props

if($result -eq "ok") 
{
    $selectedOption
}

Answer 2

You need to update your code to get value like this.

$options = @{
"A"="a"
"B"="b"
}

$props = @{
Parameters = @(
    @{Name="selectedOption"; Title="Choose an option"; Options=$options; Tooltip="Choose one."}
)
Title = "Option selector"
Description = "Choose the right option."
Width = 300
Height = 300
ShowHints = $true
}

Read-Variable @props
$selectedOption
