Focus on the first empty textBox in C#

Question

I am trying to focus on the first empty TextBox item.

How can I focus on the first empty TextBox?

Answer 1

Do a foreach loop to iterate through all TextBoxes in your Form.
Example:

foreach (TextBox tb in Controls.OfType<TextBox>()) {
    if (string.IsNullOrWhiteSpace(tb.Text)) {
        tb.Focus();
        break;
    }
}
