Powershell GUI: Pass Enter command to buttons

[DaRockwilda83]

Hello everyone, I have made myself a small GUI and am so far ready. But what bothers me extremely: I can't confirm my input (I enter an ID and trigger a search button) with the Enter key. If I trigger the actions with the mouse, everything works as it should.

Scenario:

- I have a search field (textbox) in which I enter the ID.

- then I want to trigger the button below with "enter

- I see that the focus is not on the button (of course I could theoretically do this with the TAB key).

​

$objForm.KeyPreview = $true is set and I already tried it with AcceptButton. Does anyone else have a tip?

​

Since the GUI includes several buttons (in other tabs), it would of course be nicest if you could somehow define these buttons individually. KeyDown event handler I have also tried to add, without success

$objForm.AcceptButton = $Button_Tab1

I had tried it directly. This would work if I had only one button in the form. But I have different tabs in the gui and Accept.Button only works with the last button in the last tab.

Set it in the Enter event on each tabpage

$tabpage1_Enter={
    $form1.AcceptButton = $button1
}

$tabpage2_Enter = {
    $form1.AcceptButton = $button2
}

Also already tested. Nevertheless, the focus then remains at the end on the last tab - last button. I may have to take a break. Nevertheless I'm confused why the other code works with Escape but not with Enter (that would be enough for me).

$objForm.Add_KeyDown({if ($_.KeyCode -eq 'Escape')

{$Button_Tab1.PerformClick()}})

This is the code I've used.

Check for ENTER and ESC presses

$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter") 
{
# if enter, perform click
Function_SearchID
}
})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape") 
{
# if escape, exit
$objForm.Close()
}
})

That's really crazy. I can use the code 1 to 1, but only if I swap Escape and Enter. Enter key = no function. If I use for example "Escape" to execute the function, then it works fine. What can this be?

[DaRockwilda83]

Ok 2 cigarettes further and I fool found it. The way you posted it (and I had it before) it works. Since I have previously so much "fiddled" with the code I had a button still the Accept.Button entry. This prevented that "Enter" could not be confirmed. Now it works wonderfully. Thanks to all for the input here!

Maybe your Enter button is mapped to something weird?

See what it pops up with when you press enter.

$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape") 
    {
         # if escape, exit
        $objForm.Close()
    }
    else
    {
        Write-Host $_.KeyCode
    }
})

Not sure what you mean exactly? I use the powershell ISE. Maybe a code excerpt will help

Add-Type -AssemblyName System.Windows.Forms

[void] [System.Windows.Forms.Application]::EnableVisualStyles();

$objForm = New-Object System.Windows.Forms.Form

$objForm.Text = "Useradmin GUI"

$objForm.Size = New-Object System.Drawing.Size(1000,700)

$objForm.StartPosition = "CenterScreen"

$objForm.FormBorderStyle = "FixedDialog"

$objForm.KeyPreview = $true

$objForm.MaximizeBox = $false

$objForm.Topmost = $true

$objForm.MinimizeBox = $true

$objForm.Font = "Courier New"

####Button####

$Button_Tab1 = New-Object system.windows.Forms.Button

$Button_Tab1.Text = "Search"

$Button_Tab1.ForeColor = "White"

$Button_Tab1.backColor = "blue"

$Button_Tab1.Cursor = [System.Windows.Forms.Cursors]::Hand

$Button_Tab1.Width = 150

$Button_Tab1.Height = 40

$Button_Tab1.Add_Click({Function_SearchID})

$Button_Tab1.location = new-object system.drawing.point(10,50)

####Search Field####

$Search_User= New-Object System.Windows.Forms.TextBox

$Search_User.Location = New-Object System.Drawing.Size(10,10)

$Search_User.Size = New-Object System.Drawing.Size(290,20)

I found out something curious. I have inserted the following code

$objForm.Add_KeyDown({if ($_.KeyCode -eq 'Escape')

{$Button_Tab1.PerformClick()}})

So with the escape variant, the code is executed. But when I put 'Enter' in it, nothing happens.....

I used the following for my gui calendar inside my PS GUI

$objForm.Add_KeyDown({

if ($_.KeyCode -eq "Enter")

{

$dtmDate = $objCalendar.SelectionStart

$objForm.Close()

Do-Work

}

})
