作者:春山 / 发布于2016/8/10/ 469

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;
            }
        }
