工作中遇到一个场景:在DataGridView上单击鼠标右键弹出快捷菜单,在快捷菜单内需要有“删除本行”、“清空数据”等按钮,于是我就自己实现了一个:
实现步骤如下:
步骤1,建立一个C#下的Windows窗体应用程序,取名DgvMenuStripTest
步骤2,主窗体内的控件只有一个名为dgvTest的DataGridView,对这个DataGridView启用添加、启用编辑、启用删除,并设置其在父容器中停靠
步骤3,为这个DataGridView添加MouseClick事件,代码如下:
/// <summary> /// DataGridView鼠标单击事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void dgvTest_MouseClick(object sender, MouseEventArgs e) { //当前操作的DataGridView DataGridView dgv = sender as DataGridView; //当前鼠标位置的行列信息 int col = dgv.HitTest(e.X, e.Y).ColumnIndex; int row = dgv.HitTest(e.X, e.Y).RowIndex; //右键弹出菜单 if (e.Button == System.Windows.Forms.MouseButtons.Right) { //允许用户添加行时,最后一行为未实际添加的行,因此不需考虑弹出菜单 if (row < 0 || (dgv.AllowUserToAddRows && row == dgv.Rows.Count - 1)) { return; } else { //取消选中当前所有选中的行和单元格 for (int i = 0; i < dgv.Rows.Count; i++) { dgv.Rows[i].Selected = false; for (int j = 0; j < dgv.Columns.Count; j++) { dgv.Rows[i].Cells[j].Selected = false; } } //选中当前鼠标所在的行 dgv.Rows[row].Selected = true; } //建立快捷菜单 ContextMenuStrip contextMenuStrip = new ContextMenuStrip(); ////功能 //contextMenuStrip.Items.Add("功能1"); //contextMenuStrip.Items.Add("功能2"); //contextMenuStrip.Items.Add("功能3"); ////分隔线 //contextMenuStrip.Items.Add(new ToolStripSeparator()); //删除当前行 ToolStripMenuItem tsmiRemoveCurrentRow = new ToolStripMenuItem("删除本行"); tsmiRemoveCurrentRow.Click += (obj, arg) => { dgv.Rows.RemoveAt(row); }; contextMenuStrip.Items.Add(tsmiRemoveCurrentRow); //清空所有数据 ToolStripMenuItem tsmiRemoveAll = new ToolStripMenuItem("清空数据"); tsmiRemoveAll.Click += (obj, arg) => { dgv.Rows.Clear(); }; contextMenuStrip.Items.Add(tsmiRemoveAll); contextMenuStrip.Show(dgv, new Point(e.X, e.Y)); } }
END
C#:使用快捷菜单(ContextMenuStrip)删除DataGridView控件指定行
