如何在不按Ctrl键的情况下选择datagridview的多个单元格？

Question

I have a datagridview control which i am using to make a weekly schedule.

User can select different time of different days by selecting multiple cells from the gridview.

Problem here is that once the user selects multiple cells for the first time and would like to select more cells , he need to press the Ctrl key from the keyboard which is very difficult for end user to use as in the case if he/she has no keyboard available or he is not aware of pressing Ctrl key.

I have attached a snapshot. Please provide me any solution if you have.

Answer 1

也许您可以通过DataGridView的CellMouseDown ， CellMouseMove和CellMouseUp事件来实现。

Answer 2

You can use input simulator for holding Control key and as Wudge mentioned with mouse events you can solve your issue.

private void Form1_Load(object sender, EventArgs e)
        {
            List<Person> mypeople = new List<Person>();
            mypeople.Add(new Person() { Key = 3, Value = "Turgay" });
            mypeople.Add(new Person() { Key = 4, Value = "Hamsi" });
            mypeople.Add(new Person() { Key = 5, Value = "Cabbar" });

            dataGridView1.DataSource = mypeople;


            dataGridView1.MouseEnter += DataGridView1_MouseEnter;
            dataGridView1.MouseLeave += DataGridView1_MouseLeave;
        }

        private void DataGridView1_MouseEnter(object sender, EventArgs e)
        {
            InputSimulator.SimulateKeyDown(VirtualKeyCode.CONTROL);
        }

        private void DataGridView1_MouseLeave(object sender, EventArgs e)
        {
            InputSimulator.SimulateKeyUp(VirtualKeyCode.CONTROL);
        }
