vs .net winfrm窗体数据库的表中怎么插入按钮

绑定数据源后，增加一列就可以了

DataGridViewButtonColumn dgvbc = new DataGridViewButtonColumn()
            {
                CellTemplate = new DataGridViewButtonCell(),//类型为按钮                
                Name = "充值",
                HeaderText = "充值",
                UseColumnTextForButtonValue = true,
                Text = "充值",                
            };
            this.dataGridView1.Columns.Add(dgvbc);
