ผมเขียน C# แบบ Smart Device นะครับ คือ ผมใช้คำสั่ง inputPanel1.Enabled = true; เพื่อเรียกใช้คีย์บอร์ดมาใช้งาน ซึ่งผมอยากทราบว่าตอนที่เราคลิกปิดคีย์บอร์ด

private void textBox1_GotFocus(object sender, System.EventArgs e)
{
    // Display the SIP. 
    // Note that the EnabledChanged event occurs 
    // whenever the SIP is enabled or disabled.
    inputPanel1.Enabled = true;

}
//ตรงนี้ครับ
private void inputPanel1_EnabledChanged(object sender, EventArgs e)
{
    if (inputPanel1.Enabled == false)
    {
        // The SIP is disabled, so set the height of the tab control 
        // to its original height with a variable (TabOriginalHeight), 
        // which is determined during initialization of the form.
        VisibleRect = inputPanel1.VisibleDesktop;
        tabControl1.Height = TabOriginalHeight;
    }
    else
    {
        // The SIP is enabled, so the height of the tab control 
        // is set to the height of the visible desktop area.
        VisibleRect = inputPanel1.VisibleDesktop;
        tabControl1.Height = VisibleRect.Height;
    }

    // The Bounds property always returns a width of 240 and a height of 80 
    // pixels for Pocket PCs, regardless of whether or not the SIP is enabled.
    BoundsRect = inputPanel1.Bounds;

    // Show the VisibleDestkop and Bounds values 
    // on the second tab for demonstration purposes.
    VisibleInfo.Text = String.Format("VisibleDesktop: X = {0}, " +
        "Y = {1}, Width = {2}, Height = {3}", VisibleRect.X,
        VisibleRect.Y, VisibleRect.Width, VisibleRect.Height);
    BoundsInfo.Text = String.Format("Bounds: X = {0}, Y = {1}, " +
        "Width = {2}, Height = {3}", BoundsRect.X, BoundsRect.Y,
        BoundsRect.Width, BoundsRect.Height);
}

 inputPanel1.Enabled = true
