dataGridView右键菜单并选中该行

程序代码：

private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                if (e.RowIndex >= 0)
                {
                    dataGridView1.ClearSelection();
                    dataGridView1.Rows[e.RowIndex].Selected = true;
                    dataGridView1.CurrentCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
                    contextMenuStrip1.Show(MousePosition.X, MousePosition.Y);
                }
            }
        }

去掉带*好的左边的那一列：

把DataGridView 的RowHeadervisible设置成false

private void dataGridView1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)

{

if (e.Button == MouseButtons.Right)

{

contextMenuStrip1.Show(MousePosition.X, MousePosition.Y);

}

//上移

private void btnMoveUp_Click(object sender, EventArgs e)

{

for (int i = 0; i < listView1.SelectedItems.Count; i++)

{

System.Windows.Forms.ListViewItem listViewItem = this.listView1.SelectedItems[i];

int index = this.listView1.SelectedItems[i].Index - 1;

if (index < 0) return;

this.listView1.Items.Remove(this.listView1.SelectedItems[i]);

this.listView1.Items.Insert(index, listViewItem);

listViewItem.Selected = true;

}

//下移

private void btnMoveDown_Click(object sender, EventArgs e)

{

for (int i = this.listView1.SelectedItems.Count - 1; i > -1; i--)

{

System.Windows.Forms.ListViewItem listViewItem = this.listView1.SelectedItems[i];

int index = this.listView1.SelectedItems[i].Index + 1;

if (index > this.listView1.Items.Count - 1) return;

this.listView1.Items.Remove(this.listView1.SelectedItems[i]);

this.listView1.Items.Insert(index, listViewItem);

listViewItem.Selected = true;

}
