Question

有哪位知道Winform中 datagridview多选是怎么实现的？效果如下图：
求指点

Answer 1

可以在单元格绑定一个可以多选的控件http://hi.baidu.com/wangcaidpj219x/blog/item/44d6a730bf923514ebc4af89.html

Answer 2

ListBox
属性MultiSelect为true。

Answer 3

你是要多选datagridview的行还是listbox的行，datagridview多先加一列复选框列datagridCheckBoxcolumns，绑定就可以实现多选，listbox多选如二楼所述

Answer 4

 private void dgvSetWorkGroup_Click(object sender, EventArgs e)
        {
            if (dgvSetWorkGroup.CurrentCell.ColumnIndex==4)
            {
                Rectangle rect = dgvSetWorkGroup.GetCellDisplayRectangle(dgvSetWorkGroup.CurrentCell.ColumnIndex, dgvSetWorkGroup.CurrentCell.RowIndex, false);
                ListBox lb = new ListBox();
                lb.FormattingEnabled = true;
                lb.ItemHeight = 12;
                lb.Location = new Point(200, 40);
                lb.Name = "listBox1";
                //lb.Location= new Point
                lb.Size = new System.Drawing.Size(220, 88);
                lb.TabIndex = 1;
                lb.DataSource = ScanList;
                lb.DisplayMember = "MachineId";
                lb.ValueMember = "MachineId";
                lb.SelectionMode = SelectionMode.MultiSimple;
                
               lb.Left = rect.Left;
               lb.Top = rect.Top;
               lb.Width = rect.Width;
               lb.Visible = true;
               dgvSetWorkGroup.Controls.Add(lb);
               lb.MouseLeave += new EventHandler(ListLeaveClick);
            }
        } private void ListLeaveClick(object sender, EventArgs e)
        {
            ListBox lb = (ListBox)sender;
            string ListBoxValue=null;
            for (int i = 0; i < lb.SelectedItems.Count; i++)
            {
                ListBoxValue += ((System.Data.DataRowView)(lb.SelectedItems[i]))[1] + ";";
            }
            dgvSetWorkGroup.CurrentRow.Cells[4].Value = ListBoxValue;
            lb.Visible = false;
        }
