Tab Key = Button Click

[aeremis74]

I have written an app, and its all good. I did get a request though. I have a text box. When you are in the text box and you hit the enter key it activates a button I created. That works great. The request I have is that if I am in a text box and I hit the "tab" key, it would be nice if that also activated the same enter key I have defined. I tried a few different things but I'm not sure if I'm doing it. It's not working. This is what I've done....

In the events of the text box I changed the "KeyDown" event to PCText_KeyDown.

Then I added this:

$PCText_KeyDown = [System.Windows.Forms.KeyEventHandler]{
#Event Argument: $_ = [System.Windows.Forms.KeyEventArgs]
if ($_.KeyCode -eq 'Tab')
{
&$EnterButton_Click
}
}

It doesn't seem to be working though. What else am I missing?

There are a couple settings that need to be changed in order to do this but it is possible. First, select your TextBox and make sure that Multiline and AcceptsTab are both set to true.

Lastly, be sure to add $_.Handled = $true at the end of the event handler to indicate it's been handled.

Like this?

The problem I have now is that it just tabs in the field and doesn't execute the button. Thoughts?

$PCText_KeyUp=[System.Windows.Forms.KeyEventHandler]{
#Event Argument: $_ = [System.Windows.Forms.KeyEventArgs]
if ($_.KeyCode -eq 'Enter')
{
&$EnterButton_Click
}
$_.Handled = $true
}

$PCText_KeyDown=[System.Windows.Forms.KeyEventHandler]{
#Event Argument: $_ = [System.Windows.Forms.KeyEventArgs]
if ($_.KeyCode -eq 'TAB')
{
&$EnterButton_Click
}
$_.Handled = $true
}

Do I need to change these settings?

Let me find out for sure and get back to you. In the meantime I've moved the thread to the PowerShell GUI's Forum in case anyone else can provide some help.

You can make the button the next tab in the sequence.
You can use the validating event to control the results.
You can use the "lost focus" event to force the button to be next.

If a control accepts tabs then the tab action will take precedence over other events.

In my tests I couldn't get it to avoid the tab action just as Jvierra said above.

As for it running $Enter_ButtonClick, make sure 'Tab' isn't in all caps.

Well - it can be done but we have to use a different approach.

Here is a demo. Type some text an tab or enter and watch the button.
Reselecting the textbox resets the button until you type tab or enter again.
