I'm doing a Sudoku GUI in C#. All 81 textboxes are created at runtime. Their names are 11, 12, 13...19,21...98,99 respectively. At beginning the focus is in the textbox that has internally the name "11". I wish to navigate with the arrow keys. I.e. with the downkey I want to transfer the input focus to the textox "21". How can I do this? I didn't find a solution checking some C# books and the internet.
Thanks for any help.
