I have 3 rickboxes in the form. I fill them at different times. When the last rickbox is filled, I want the column named “tamamlandi” that contains the bool value to mark as checked. But I couldn't succeed. I need your help on this matter.
This is my code.
string kayit = "update mytablename set tamamlandi=@tamamlandi
if (txt_gorusme1.Text != string.Empty && txt_gorusme2.Text != string.Empty && txt_gorusme3.Text != string.Empty) { komut.Parameters.AddWithValue("@tamamlandi", true); } else { komut.Parameters.AddWithValue("@tamamlandi", DBNull.Value); }
