C# winform窗体，form1为软键盘，form2上有textbox，那么如何使用软键盘在form2的textbox内输入数据
form1软键盘是可以使用的，在网页上，QQ对话框等都是可以输入数据的，好像是焦点的问题，但是我点击使用软键盘form1的时候，焦点就在form1上了。怎样让焦点在textbox上，使用软键盘在textbox上输入数据
namespace Test
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Form2 f = new Form2();
f.Press += MiniKeyboardHandler;
f.ShowDialog();
}
private void MiniKeyboardHandler(object sender, MiniKeyboardArgs e)
{
textBox1.Text += e.KeyCode;
}
}
}
namespace Test
{
//模拟小键盘
public partial class Form2 : Form
{
public delegate void MiniKeyboardHandler(object sender, MiniKeyboardArgs e);
public event MiniKeyboardHandler Press;
public Form2()
{
InitializeComponent();
BindEvent();
}
private void BindEvent()
{
foreach (Control ctl in this.Controls)
{
if (ctl is Button)
ctl.Click += MinikeyboardPress;
}
}
private void MinikeyboardPress(object sender, EventArgs e)
{
OnMiniKeyboardHandle(new MiniKeyboardArgs(((Button)sender).Text));
}

{
MiniKeyboardHandler temp = Press;
if (temp != null)
temp(this, e);
}
}
public class MiniKeyboardArgs : EventArgs
{
public string KeyCode { get; private set; }
public MiniKeyboardArgs(string code)
{
KeyCode = code;
}
}
