给你个比较好用的

C# code

public DataGridViewTextBoxEditingControl CellEdit = null;                  private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)        {            CellEdit = (DataGridViewTextBoxEditingControl)e.Control;                    CellEdit.ShortcutsEnabled = false;            CellEdit.KeyPress += new KeyPressEventHandler(CellEdit_KeyPress);        }        private void CellEdit_KeyPress(object sender, KeyPressEventArgs e)        {           if (Char.IsNumber(e.KeyChar))            {               e.Handled = true;               MessageBox.show("Num forbiden");           }        }
