How can I allow ctrl+a with TextBox in winform?
c#, keyboard-shortcuts, textbox, winforms
Solution
Like other answers indicate, `Application.EnableVisualStyles()` should be called. Also the `TextBox.ShortcutsEnabled` should be set to `true`. But if your `TextBox.Multiline` is enabled then Ctrl+A will not work (see MSDN documentation). Using `RichTextBox` instead will get around the problem.
Problem
I'm asking the question already asked (and even answered) here: Why are some textboxes not accepting Control + A shortcut to select all by default But that answer doesn't work for me. I have this code: ``` public class LoginForm : Form { private TextBox tbUsername; public LoginForm() { tbUsername = new TextBox(); tbUsername.ShortcutsEnabled = true; tbUsername.Multiline = false; Controls.Add(tbUsername); } } ``` The textbox shows up, I can write on it, I can cut, copy and paste text on it without any problems. But when I try to press Ctrl+A I only hear a "bling" similar to the bling that you hear if you try to erase text from an empty textbox (try it with your browser's address bar).
