In this post I'll describe the way to handle the exceptions in Silverlight. Whereas running the Silverlight application, if any exception happens it'll attend Silverlight.js and show within the internet explorer as a javascript error. Within the debugging purpose of read typically it's cumbersome to see wherever truly the exception happened.

LogWindow.xaml
This is an easy user control that has an easy textbox:
<TextBox
AcceptsReturn="True"
TextAlignment="Left"
TextWrapping="NoWrap"
VerticalScrollBarVisibility="Visible"
x:Name="logText"
FontFamily="Courier New"
FontSize="12" IsReadOnly="True" HorizontalScrollBarVisibility="Auto" />

Logger.cs
This class are used to print the exception and notice the stacktrace. it's an enum for the exception types viz. DEBUG,INFO,WARN,ERROR and FATAL.This class contains an easy delegate to add text to the log window. The static property _instance is about by the LogWindow.xaml.cs go in the load event as:
Logger._instance = logText;
So that it will print whatever exception happenes in your application. The LogException methodology expects exception object because the parameter and find the exception information using the StackFrame class.

StackFrame frame = new StackFrame(true);
callerSignature =  string.Format("@{0}:{1}:{2}", frame.GetMethod(), frame.GetFileName(), frame.GetFileLineNumber());

To use this method in your catch block you just simply need to call the static method as:
Catch(Exception ex)
{
Logger.LogException(ex);
}

Hope this tutorial works for you!

In this article let us see the distinctive methods for utilizing the property Clickmode for a Button Control in a Silverlight application. Of course, open the visual studio and select the Silverlight 5 project.

First let us drag 3 different Button and TextBlock controls to Stack Panel as shown below into MainPage.xaml. Here I utilized a property called "ClickMode" for all the three button controls, But the value assigned to it is diverse.

For the first button I allocated the quality Hover to the ClickMode property, It implies that the click event handler happens at whatever point the mouse is floated onto this button.

For the second button, I allocated the quality Press to the ClickMode property, It implies that the click occasion handler happens at whatever point the mouse is clicked on this catch.  For the third button I assigned the value Release to the ClickMode property, It implies that the click event handler happens at whatever point the mouse is discharged from this button.

<Button x:Name="btn1" Margin ="5" HorizontalAlignment="Left"
Foreground="Black" Width="320" Click="OnClick1"
Content="On Mouse Hover this text will appear below" ClickMode="Hover" />
<TextBlock x:Name="text1" Margin ="0,8,0,0" />
<Button x:Name="btn2" Margin ="5,5,5,5"  HorizontalAlignment="Left"
Foreground="Black" Width="320" Click="OnClick2"
Content="On Button Press this text will appear below" ClickMode="Press" />
<TextBlock x:Name="text2" Margin="0,8,0,0" />
<Button x:Name="btn3" Margin ="5,5,5,5" HorizontalAlignment="Left"           

Click="OnClick3" Width="320" Content="On Button Release this text will appear    below" ClickMode="Release"/>
<TextBlock x:Name="text3" Margin ="0,8,0,0" />

Now i am writing the code for button click events in the MainPage.xaml.cs
public MainPage()
        {
            InitializeComponent();
        }
        void OnClick1(object sender, RoutedEventArgs e)
        {
            btn1.Foreground = new SolidColorBrush(Colors.Blue);
            text1.Text = "On Mouse Hover this text will appear below.";
            text2.Text = "";
            text3.Text = "";
        }
        void OnClick2(object sender, RoutedEventArgs e)
        {
            btn2.Foreground = new SolidColorBrush(Colors.Green);
            text1.Text = "";
            text2.Text = "On Button Press this text will appear below.";
            text3.Text = "";
        }
        void OnClick3(object sender, RoutedEventArgs e)
        {
            btn1.Foreground = new SolidColorBrush(Colors.Green);
            btn2.Foreground = new SolidColorBrush(Colors.Blue);
            text1.Text = "";
            text2.Text = "";
            text3.Text = "On Button Release this text will appear below.";
        }

Just refresh it. And here is the output.

Output for the first Button looks like:

Output for the second Button looks like:

Output for the third Button looks like:
