How to catch TAB press in C# WinForms?

Question

C++ / C#

Hello!
How can I make C# WinForms so that when focus is on a TextBox and TAB is pressed, a tab is inserted?

Answer 1

1 option

textBox2.Multiline = true;
textBox2.AcceptsTab = true;

Option 2, keep track of PreviewKeyDown

private void textBox1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
   if (e.KeyCode == Keys.Tab)
   {
      textBox1.AppendText("\t");
      e.IsInputKey = true;
   }
}
