You are missing the styles:

&lt;style type="text/css"&gt;

#modalContainer {
    background-color:transparent;
    position:absolute;
    width:100%;
    height:100%;
    top:0px;
    left:0px;
    z-index:10000;
    background-image:url(tp.png); /* required by MSIE to prevent actions on lower z-index elements */
}

#alertBox {
    position:relative;
    width:300px;
    min-height:100px;
    margin-top:50px;
    border:2px solid #000;
    background-color:#F2F5F6;
    background-image:url(alert.png);
    background-repeat:no-repeat;
    background-position:20px 30px;
}

#modalContainer &gt; #alertBox {
    position:fixed;
}

#alertBox h1 {
    margin:0;
    font:bold 0.9em verdana,arial;
    background-color:#78919B;
    color:#FFF;
    border-bottom:1px solid #000;
    padding:2px 0 2px 5px;
}

#alertBox p {
    font:0.7em verdana,arial;
    height:50px;
    padding-left:5px;
    margin-left:55px;
}

#alertBox #closeBtn {
    display:block;
    position:relative;
    margin:5px auto;
    padding:3px;
    border:2px solid #000;
    width:70px;
    font:0.7em verdana,arial;
    text-transform:uppercase;
    text-align:center;
    color:#FFF;
    background-color:#78919B;
    text-decoration:none;
}
&lt;/style&gt;


Custom Alert Box Shows up Incorrectly
Within a Desktop app I have a toggle button: 

&lt;ToggleButton x:Name="CFStglBtn" Checked="cfsCBox_Checked"
              Unchecked="cfsCBox_Unchecked"
              IsChecked="True" HorizontalAlignment="Left" Margin="5,0,0,0"&gt;
    &lt;StackPanel Orientation="Horizontal"&gt;
        &lt;Image Source="assets\telephone.png" Margin="3,0,0,0" /&gt;
        &lt;TextBlock Text="CFS" FontSize="10" Margin="5,5,5,0"
                   Foreground="DarkSlateGray"/&gt;
    &lt;/StackPanel&gt;
&lt;/ToggleButton&gt;


For the Checked event I am setting a value and then executing a method FilterView(); 
//ommitting code 

Unchecked state is just the opposite. resets a variable and executed the method again

The question I have is I noticed when I uncheck the toggle button the button continues to pulse or flash ( going from blue to chrome) as if it still has focus. The button will stay like this until another button is clicked.

Is there a way to remove this focus so that when the button is unchecked the button goes back to a unchecked state without the flashing / pulsing color. 


As you can see from above this is a standard toggle button no styles or custom 
I tested this on just a regular button and I found the same occured when clicked the button will continue to pulse / flash until another button is clicked. 


How do you work around this or prevent this effect from happening.

Thank you
