How do you have the cursor advance to the next input field when the user hits <ENTER>

Control_KeyPress(object sender, KeyPressEventHandler e){
  if(e.KeyChar!=Keys.Enter){
    return; //skip all keys except Enter
  }

    //for tab index sorting
  int currentIndex = ((Control)sender).TabIndex;
  int nextIndex = 5000; // for tab index sorting

  Control controlToFocus = null;
  foreach(Control c in this.Controls){
    if((c.TabIndex<nextIndex)&&c.TabIndex>currentIndex)){
      if(c.TabStop){
        nextIndex = c.TabIndex;
        controlToFocus = c;
      }
    }
  }

  if(controlToFocus !=null){
    controlToFocus.Focus();
  }
}
