Add button button in datagridview

Foreword:

.Net's DataGridView control provides a column type called DataGridViewButtonColumn. This column type is displayed as a button, which can be assigned corresponding text, and this button can be used as a judgment basis for handling events.

Although the DataGridViewButtonColumn looks like a BUTTON in UI display, its actual form is not a BUTTON in the traditional sense, but a rendered style, which is completely the effect of painting. Therefore, the set of BUTTON in the traditional sense is invalid here.

Code:

//在datagridview中添加button按钮
            DataGridViewButtonColumn btn = new DataGridViewButtonColumn();
            btn.Name = "btnModify";
            btn.HeaderText = "修改";
            btn.DefaultCellStyle.NullValue = "修改";
            dataGridView1.Columns.Add(btn);  

Then write code similar to the following in the CellContentClick event of the DataGridView:

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            //点击button按钮事件
            if (dataGridView1.Columns[e.ColumnIndex].Name == "btnModify" && e.RowIndex >= 0)
            {
            //说明点击的列是DataGridViewButtonColumn列
                DataGridViewColumn column = dataGridView1.Columns[e.ColumnIndex];
                IPEntity ipentity = new IPEntity();

                ipentity.ipName = Convert.ToString(dataGridView1.CurrentRow.Cells[0].Value);
                ipentity.ipPart = Convert.ToString(dataGridView1.CurrentRow.Cells[1].Value);
                ipentity.ipStart = Convert.ToString(dataGridView1.CurrentRow.Cells[2].Value);
                ipentity.ipEnd = Convert.ToString(dataGridView1.CurrentRow.Cells[3].Value);

                bool flag = selectIp.UpdateIP(ipentity);
                if (flag)
                {
                    MessageBox.Show("更新成功！");
                }
                else
                {
                    MessageBox.Show("更新失败！");
                }
            }           
        }
