Simple - just add then up.

Code: Select all

$buttonWorld_Click={
    #TODO: Place custom script here
    $world = "World"
    $lbl.Text += $world
}

thx for your quick respond.
My goal here is how to pass variable from one event to different, showing in txtbox or label is to just show...
I am creating Azure admin tool, so if admin will click verify button, it does some stuff and create variable. This variable i want to be available to different events to call if another button press.

You cannot pass variables between events. The system owns the events and handles all parameters.
To easily share data in a form you can save the data in a control or save it is a script scope variable.

"To easily share data in a form you can save the data in a control or save it is a script scope variable"

any example you could share?

down below i would like to pass $ObjectId variable from $buttonHello to $buttonWorld and run $Results command
===============================================
$buttonHello_Click={
#TODO: Place custom script here
$ObjectId = $(Get-AzureADUser -Filter "UserPrincipalName eq '$EmpsUPN'").ObjectId
$textbox1.Text= $ObjectId
}



$buttonWorld_Click={
#TODO: Place custom script here
$world = "World"

$Results= get-AzureADUserManager -ObjectId $ObjectId -RefObjectId "test1"

$textbox1.Text += $world
}
===========================================

Here is the correct way to code something like this in Forms.

Code: Select all

$buttonHello_Click={
    $textbox1.Text = (Get-AzureADUser -Filter "UserPrincipalName eq '$EmpsUPN'").ObjectId
}

$buttonWorld_Click={
    $results = get-AzureADUserManager -ObjectId $textbox1.Text -RefObjectId test1
}
Avoid over-quoting things and avoid using syntactic constructs without understanding what they do.

Re: passing variable to another event

Post by ausman »

those are are good points but i am just testing variables with events.

So in my real gui what i am trying to build when button verification click, it runs some command in Azure and shows in label. these commands get three values in three different variables. Now, if user click another button to execute, three values variables used in this event to execute some other commands.
So, questions would be whatif more then one variables needs to pass to events?
really appreciate your help..thanks

I have absolutely no idea what you are trying to ask. You need to learn enough PowerShell to be able to ask a basic question.
To persist variables in an event use scoping to set the scope to "script" or "global" and the variables will be available in any other event.
