TextBox, hiding text once sent

I have a script where a button is clicked, things happen (that works all dandy) yet, after all that I want to textbox be set back to the PlaceholderText, how would I do that?

I tried setting the text to just blank spaces but well, it shows up as blank space and now Placeholder text

So do you want the PlaceHolderText to not show up?

Nooooo, I want the Placeholder text to show up once the button is pressed, like it resets the TextBox basically.

^ like remove text and only have Placeholder text

textbox.Text = "" works for me, as long as textbox.PlaceholderText is set to something too.

Ah! I probably should’ve tried that aswell, thank you
