private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) 
{ 
dataGridView1.Rows[e.RowIndex].ErrorText = string.Empty; 
if(dataGridView1.Columns[e.ColumnIndex].DataPropertyName == "A") 
{ 
Regex rx = new Regex(@"^[1-9]\d*$", RegexOptions.Compiled);
if (rx.IsMatch(e.FormattedValue.ToString()))
{ dataGridView1.Rows[e.RowIndex].ErrorText = "输入有误！"; 
e.Cancel = true; }

} 
}

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");
           }

        }
