然后在contextMenuStrip控件上添加两个菜单,全选和反选,然后就再写点代码
namespace button
{
public partial class Form1 : Form
{
public Form1()
{

DataGridViewCheckBoxColumn db = new DataGridViewCheckBoxColumn();
db.Name = "选择";
dataGridView1.Columns.Add(db);
} private void toolStripMenuItem1_Click(object sender, EventArgs e)//全选
{ for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
{
this.dataGridView1["选择", i].Value = true;
}
} private void toolStripMenuItem2_Click(object sender, EventArgs e)//反选
{
for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
{
this.dataGridView1["选择", i].Value = false;
} } }
