使用 KeyUp 事件在数据网格中选择值

我想通过使用KeyUp和KeyDown事件将数据网格视图中的选定值显示在文本字段中 

private void gridView_KeyUp(object sender, KeyEventArgs e)
{
    try
    {
        //if (e.RowIndex >= 0)
        if(e.KeyCode == Keys.Up)
        {
            DataGridViewRow row = this.gridView.Rows[e.KeyCode];
            txtboxStudentNum.Text = row.Cells["ID_Number"].Value.ToString();
            txtboxName.Text = row.Cells["Name"].Value.ToString();
            comboCourse.SelectedItem = row.Cells["Course"].Value.ToString();
            EPCdisplay.Text = row.Cells["EPCNumber"].Value.ToString();
            txtboxSerialNum.Text = row.Cells["SerialNumber"].Value.ToString();
            txtboxModelNum.Text = row.Cells["ModelNumber"].Value.ToString();
            comboCategory.SelectedItem = row.Cells["Category"].Value.ToString();
            comboYrLevel.SelectedItem = row.Cells["Level"].Value.ToString();
            txtboxEquipDesc.Text = row.Cells["EquipDesc"].Value.ToString();
            comboSem.Text = row.Cells["Semester"].Value.ToString();

            AddDatabase get_image = new AddDatabase();
            get_image.ID = txtboxStudentNum.Text;
            get_image.getimage();

        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

使用 KeyUp 事件在数据网格中选择值

如果您希望获取所选单元格的值，那么您所需要做的就是触发 DataGridView KeyDown 事件并将代码编写为 

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            txtName.Text = dataGridView1.CurrentCell.Value.ToString();
            //do whatever you want to
        }
    }

如果你想获取整行并执行操作，你可以这样做

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            int row = dataGridView1.CurrentCell.RowIndex;
            txtID.Text = dataGridView1.Rows[row].Cells[0].Value.ToString();
            txtName.Text = dataGridView1.Rows[row].Cells[1].Value.ToString();
            //do whatever you want to
        }
    }
