Hey everyone! I'm trying to get a PowerShell script to work where I can click buttons to copy specific text to my clipboard, but it's not going as smoothly as I hoped. Every button shows the content of the last button defined instead of its own. I've tried using the `Tag` property to store unique strings for each button, but that didn't work either. Here's what I've got so far: I've created a button for each item in a list with some basic code but they all reference the same last value when clicked. Any ideas on how to fix this? Thanks in advance!

Honestly, you don’t need to complicate things with content at all. You can set the clipboard directly in the button click event itself. That's where you handle the button actions anyway, so just make sure to do all your clipboard management there. It should streamline your code a lot.
You're running into a common issue in PowerShell with script blocks. When you set up the button's `Click` event, it uses the current scope, which is why everything points to the last button's value. You can resolve this by calling `GetNewClosure()` on your script block. This makes it capture the value at that moment instead of referring to the loop variable later. Check out this line:
```powershell
$button.Add_Click({ Set-Clipboard -Value $_.content }.GetNewClosure())
```
This should do the trick! Let me know if you need more clarification.
This is super helpful, thanks! I always run into scope issues and now I feel more confident tackling it.
Are you sure you're using `.Content` correctly? If you're only referencing the button name during the event, you might want to double-check how you're accessing values. You could use `$this.Text` within your button click handler to find out which button was clicked, like this:
```powershell
$button.Add_Click({ Set-Clipboard -Value $($buttons | Where-Object { $_.Name -eq $this.Text }).Content })
```
That way you're directly determining the content based on the button name. Let me know if that helps!
Ah, good catch! I initially pasted a different version of the code in there. Thanks for pointing that out; I’ll make the necessary corrections! Also, I'm not fully grasping the `$sender` reference yet—just trying to learn here.
Exactly! Just remember to declare the content variable outside your script block, like so:
```powershell
$content = $_.content
$button.Add_Click({ Set-Clipboard -Value $content }.GetNewClosure())
```
This ensures it references the correct value when the button is clicked.
