I am trying to create my first Windows phone application but I keep getting this "XamlParseException" thrown at me.It looks like the error is coming from the InitializeComponent() method which is a shock because it was automatically created by VS.
Here is the Exception :
XamlParseException Failed to assign to property 'System.Windows.FrameworkElement.Loaded'. [Line: 14 Position: 39]
Here is the code behind :
namespace WinHomeWork1
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
private void PhoneApplicationPage_Loaded(object sender, TextChangedEventArgs e)
{
myTextBox.Focus();
}
private void ClickMe_Click(object sender, RoutedEventArgs e)
{
if (myTextBox.Text.CompareTo("1 2 3 4") == 0)
{
myTextBlock.Text = "You have won!";
}
else
myTextBlock.Text = "You have Lost";
}
}
}
Here is the Xaml Code :

The program has only 3 elements, 1) A TextBox 2) A TextBlock and a 3) Button. The user inputs data into the textBox then clicks a "Go" button, if the input is "1 2 3 4" the app will display "You have Won" in the textBlock, if any other input has been entered it will display " You have lost".Please Help, I do not know any Xaml so I can't play around with the Xaml code.
Your error is due to PhoneApplicationPage_Loaded event handler method. It should be like this:
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
myTextBox.Focus();
}
Change the parameter e
in your PhoneApplicationPage_Loaded
to an instance of the RoutedEventArgs
class:
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
myTextBox.Focus();
}
