Значение свойства

Тип: System.Int32
The vertical, or y-axis, location of the top edge of the PenInputPanel object, in screen coordinates.

Заметки

To explicitly override the automatic positioning behavior of the PenInputPanel object, use the Left and Top properties of the object to determine the current position of the pen input panel.

You can also override the automatic positioning behavior of the PenInputPanel object by listening for the Left and Top properties of the PenInputPanelMovingEventArgs object during a PanelMoving event.

Примечание о безопасности.
If using under partial trust, this property requires SecurityPermissionFlag.AllFlags permission, in addition to the permissions required by PenInputPanel. See Security and Trust for more information.

This C# example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, theInkEdit. It then attaches a VisibleChanged event handler, VisibleChanged_Event. The event handler uses the Top property to add a sentence to the content of theInkEdit, stating where the top edge of the PenInputPanel object is located, in screen coordinates.

[C#]

//...

// Declare the PenInputPanel object
PenInputPanel thePenInputPanel;

public Form1()
{
    // Required for Windows Form Designer support
    InitializeComponent();

    // Create and attach the new PenInputPanel to an InkEdit control.
    thePenInputPanel = new PenInputPanel(theInkEdit);

    // Add a VisibleChanged event handler
    thePenInputPanel.VisibleChanged +=
        new PenInputPanelVisibleChangedEventHandler(VisibleChanged_Event);
}

//...

public void VisibleChanged_Event(object sender,
                                 PenInputPanelVisibleChangedEventArgs e)
{
    // Make sure the object that generated
    // the event is a PenInputPanel object
    if (sender is PenInputPanel)
    {
        PenInputPanel theSenderPanel = (PenInputPanel)sender;

        // When the panel has become visible...
        if (e.NewVisibility)
        {
            // Display the top edge of the panel
            // in the attached edit control
            theSenderPanel.AttachedEditControl.Text +=
                    "The top edge of the panel is at ";
            theSenderPanel.AttachedEditControl.Text += theSenderPanel.Top.ToString();
            theSenderPanel.AttachedEditControl.Text += " pixels.\n";
