I want to take input dynamically by using the touch event for that I used this code
using System; using System.Windows; using System.Windows.Input; using System.Windows.Media; using System.Windows.Shapes; namespace CallApp { public partial class MainPage : Microsoft.Phone.Controls.PhoneApplicationPage { // Constructor public MainPage() { InitializeComponent(); Touch.FrameReported += new TouchFrameEventHandler(Touch_FrameReported); // Sample code to localize the ApplicationBar //BuildLocalizedApplicationBar(); } Point pt1, pt2 = new Point(); void Touch_FrameReported(object sender, TouchFrameEventArgs e) { if (this.canvas1 != null) { foreach (TouchPoint _touchPoint in e.GetTouchPoints(this.canvas1)) { if (_touchPoint.Action == TouchAction.Down) { // Clear the canvas and capture the touch to it. this.canvas1.Children.Clear(); _touchPoint.TouchDevice.Capture(this.canvas1); } else if (_touchPoint.Action == TouchAction.Move && e.GetPrimaryTouchPoint(this.canvas1) != null) { // This is the first (primary) touch point. Just record its position. if (_touchPoint.TouchDevice.Id == e.GetPrimaryTouchPoint(this.canvas1).TouchDevice.Id) { pt1.X = _touchPoint.Position.X; pt1.Y = _touchPoint.Position.Y; } // This is not the first touch point. Draw a line from the first point to this one. else if (_touchPoint.TouchDevice.Id != e.GetPrimaryTouchPoint(this.canvas1).TouchDevice.Id) { pt2.X = _touchPoint.Position.X; pt2.Y = _touchPoint.Position.Y; Line _line = new Line(); _line.Stroke = new RadialGradientBrush(Colors.White, Colors.Black); _line.X1 = pt1.X; _line.X2 = pt2.X; _line.Y1 = pt1.Y; _line.Y2 = pt2.Y; _line.StrokeThickness = 2; this.canvas1.Children.Add(_line); } } else if (_touchPoint.Action == TouchAction.Up) { // If this touch is captured to the canvas, release it. if (_touchPoint.TouchDevice.Captured == this.canvas1) { this.canvas1.ReleaseTouchCapture(_touchPoint.TouchDevice); } } } } } // Sample code for building a localized ApplicationBar //private void BuildLocalizedApplicationBar() //{ // // Set the page's ApplicationBar to a new instance of ApplicationBar. // ApplicationBar = new ApplicationBar(); // // Create a new button and set the text value to the localized string from AppResources. // ApplicationBarIconButton appBarButton = new ApplicationBarIconButton(new Uri("/Assets/AppBar/appbar.add.rest.png", UriKind.Relative)); // appBarButton.Text = AppResources.AppBarButtonText; // ApplicationBar.Buttons.Add(appBarButton); // // Create a new menu item with the localized string from AppResources. // ApplicationBarMenuItem appBarMenuItem = new ApplicationBarMenuItem(AppResources.AppBarMenuItemText); // ApplicationBar.MenuItems.Add(appBarMenuItem); //} } }
But it giving error at
if (_touchPoint.TouchDevice.Captured == this.canvas1) { this.canvas1.ReleaseTouchCapture(_touchPoint.TouchDevice); }
That missing Some Assemblies or Directive
