XamlParerException: while trying to link text to Xaml page - xaml

Question

(Windows Phone Project ) I am trying to create a scenario were a user would click a text and a xaml page would be displayed be display.
The text is called "Terms and Condition".
Event code for the text component
private void MouseEnter_Agent(object sender, System.Windows.Input.KeyEventArgs e)
{
this.NavigationService.Navigate(new Uri("/AgentTerms.xaml", UriKind.Relative));
}
The Xaml interface code
<TextBlock TextWrapping="Wrap" Height="30" Foreground="Red" MouseEnter="MouseEnter_Agent">
<Underline>
<Run Text="Read JizAgent Terms and Conditions"/>
</Underline>
<LineBreak/>
<Run/>
</TextBlock>
I get the error when I click the text - XamlParerException

Answer 1

You're using the wrong EventArgs class in your event handler's signature. You should be using MouseEventArgs. Take this basic example:
<Window x:Class="MouseEventArgs.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MouseEventArgs" Height="300" Width="300">
<Grid x:Name="LayoutRoot"
Background="Green"
MouseEnter="Grid_MouseEnter" />
</Window>
Code behind:
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
namespace MouseEventArgs
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
void Grid_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
{
LayoutRoot.Background = new SolidColorBrush(Colors.Red);
}
}
If this fails then it would have to be an issue with the markup in AgentTerms.xaml.

Answer 2

void MouseEnter_Agent(object sender, System.Windows.Input.KeyEventArgs e)
The signature of the handler is wrong. Replace it with:
void MouseEnter_Agent(object sender, System.Windows.Input.MouseEventArgs e)
