I have a search page with 3 TextBoxes that users can filter a search with.

I have put the focus on the TextBox that contains text. If more than one contains text just focus on last TextBox.

private void SetFocusOnTextBox(ControlCollection ctrlCollection)
{
    foreach (Control ctrl in ctrlCollection)
    {
        if (ctrl.GetType() == typeof(TextBox))
        {
            if (((TextBox)ctrl).Text != string.Empty)
            {
                SetFocus(ctrl);
            }
        }
    }
}

After the code runs and a user searches, the focus comes to the beginning of the TextBox, not the end where it would be presumed. How to put insert marked at the end of that TextBox?
