Question

在盒子中,是否可以只使用键盘打1 NET DataGridView栏?

I understand there is a SelectionMode property, but changing this merely allows me to select, using Shift+Space, an entire row or column, but this doesn t have the same effect as clicking the header with the mouse and causing a sort.

我要求的是,因为我正在处理无障碍问题,希望避免依赖这种使用。

感谢任何援助。

Answer 1

The first thing you will need to do is set the KeyPreview property to True in your form properties.

然后,在活动中,你需要为<代码>KeyDown()活动添加一个活动手。

Then add some code something like this:

public class Form1{
this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);

private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        //sort column 0 descending on a  D  press
        if (e.KeyCode == Keys.D)
            dataGridView1.Sort(dataGridView1.Columns[0], ListSortDirection.Descending);

        //sort column 0 Ascending on a  U  press
        if (e.KeyCode == Keys.U)
            dataGridView1.Sort(dataGridView1.Columns[0], ListSortDirection.Ascending);
    }
}

Answer 2

May be I m missing something, but call Sort method at the moment you receive desired Key combination.

Answer 3

i don t know that the column headers ever get focus (ctrl+tab/etc?), but if they could and your keyboard has a context menu button, that could work. but i don t think the headers ever get keyboard focus.

Otherwise, there may be ways to do it using standard accessability features?
