)

You cannot use methods in XAML.

Parameters

element

The element to capture the stylus to.

Return Value

true if the stylus is captured to element; otherwise, false.

Use the Capture(IInputElement) method to ensure that element receives stylus events even when the cursor goes out of bounds of element. To release the stylus, call Capture(IInputElement,CaptureMode) with the CaptureMode set to None.

The Capture(IInputElement) method returns false if element is not visible or enabled.

The following example demonstrates how to record the coordinates of the stylus, even if the stylus leaves the bounds of a TextBox. This example assumes there is a TextBox called textBox1, and that the StylusDown, StylusUp, and StylusMove events are connected to the event handlers.

void textbox1_StylusDown(object sender, StylusDownEventArgs e)
{
    Stylus.Capture(textbox1);
}

void textbox1_StylusMove(object sender, StylusEventArgs e)
{
    Point pos = e.GetPosition(textbox1);
    textbox1.AppendText("X: " + pos.X + " Y: " + pos.Y + "\n");
}

void textbox1_StylusUp(object sender, StylusEventArgs e)
{
    Stylus.Capture(textbox1, CaptureMode.None);
}
