Hi
I am developing a window application in C#. I have a listbox filled with country names.
When that form is opened and a key is pressed say G, the country Germany shows at the bottom of the display area. But i want it to display at the top of the display area( listbox).

Thanks,

推荐答案

在列表框中按键；

In the listbox keypress;

private void listBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    //Find the first item that starts with the keypressed, and set it to the top of the list
        listBox1.TopIndex =listBox1.FindString(e.KeyChar.ToString(), 0);
}
