Go to next text box when enter is pressed

Question

Hello in my WinForms application i have this below program which helps to Go to next text box when enter key is pressed , But i am facing an issue here .
When I press enter key after I type something or without typing anything in first textbox it is going to next text box.
But if I type something accidentally and hit backspace to erase the first textbox content and if I press enter key then it is not moving to next textbox , Kindly help how to solve this issue.

private void Form1_Shown(object sender, EventArgs e)
        {
            try
            {
                foreach (Control control in Controls)
                {
                    if (control is TextBox textBox)
                    {
                        textBox.KeyDown += (s, ea) =>
                        {
                            if (ea.KeyCode != Keys.Enter) return;
                            ea.SuppressKeyPress = true;
                            SelectNextControl(ActiveControl, true, true, true, true);
                        };
                    }
                    else if (control is ComboBox comboBox)
                    {
                        comboBox.KeyDown += (s, ea) =>
                        {
                            if (ea.KeyCode != Keys.Enter) return;
                            ea.SuppressKeyPress = true;
                            SelectNextControl(ActiveControl, true, true, true, true);
                        };
                    }
                    else if (control is DateTimePicker dateTimePicker)
                    {
                        dateTimePicker.KeyDown += (s, ea) =>
                        {
                            if (ea.KeyCode != Keys.Enter) return;
                            ea.SuppressKeyPress = true;
                            SelectNextControl(ActiveControl, true, true, true, true);
                        };
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Enter Failed:" + ex.Message.ToString(), "Enter",
                    MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }

And I made a test, it worked fine.
The test result:
