Advancing On Pressing Enter

Roger Wright

I have a User control that contains three radio buttons - rbCirc, rbRect, and rbTrap - representing 3 possible shapes, and three textboxes for user values. I'm used to programs that automatically advance to the next item in the tab order when I press Enter, but I haven't been able to duplicate that behavior. Tab works as expected, but Enter just makes a "Bonk" sound, at least in the debugger. What can I do to make the focus advance when a user presses Enter?

In the KeyDown event for the form, see if the key hit is enter and if so, write code to proceed

I do not know how to avoid sound. But you can achieve the behavior by tracking keypress event

private void radioButton1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == 13)
{
Yourcontrol.Focus();
}
}

Hy, Use the KeyDown event and compare:

if(e.KeyCode == Keys.Enter){
e.Handled = true;//stops the beep/bonk noise
e.SupressKeyPress = true;//it bypasses the KeyPress event

txtYouNameIt.Focus();//focuses on the control you specify
}

Something like that should work

Thanks, Jinal! It works great! :-D

Thanks! This is a little more general solution, and good for a User Control intended for re-use.

Hi Roger, The answers give already, work perfectly well in circumstances where you know the Name of the control that you want to go to and are prepared to write an individual KeyDown/Keypress (select your poison) handler for each control. However, for circumstances where you want to simply follow the TabOrder you have already set and, where applicable, use one handler for several controls, the System.Windows.Forms.Control class has a built in method to do exactly what you want. Look up the System.Windows.Forms.Control.GetNextControl() method. An example:

  private void Comunal\_KeyDownHandler(object sender, System.Windows.Forms.KeyEventArgs e)
  {
     if (e.KeyCode == Keys.Enter)
     {
         e.Handled = true;
         // true means go forwards
         this.GetNextControl((Control)sender, true).Focus();
     }
  }

This way you can assign the handler to all the controls in your User Control, provided that you are not already using their KeyDown event for something else.

Everything already said will work, but you might also want to consider the "KeyPreview" property of the Form. This lets the Form see the key-press before it goes to any controls, so it allows you to create a handler at the Form level instead of a handler for each individual control. Another advantage is that all your code will be inside a single handler instead of spread out among all the various controls.
