I am new in Universal app development. Can any one help me into following code,

I have load one website using web view control in universal app. I want to read some control value from same website. My label control id is 'lblDestination' on website.

I am accessing this in universal app like MAinPage.xaml

<WebView x:Name="Browser" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Loaded="Browser_Loaded" NavigationFailed="Browser_NavigationFailed"> </WebView>

MAinPage.xaml.cs

Browser.InvokeScript("eval", new string[] { "document.getElementById``('lblDestination')" }).ToString()**

Is this right way to read the browser control value? I am using the simulator for testing this app, So is simulator creating the problem?

What I have tried:

Not able to get and set value for web site control using universal app development.
