c# call javascript function written in hosting application from webview control in client application

Question

I have a UWP app using Webview control. The source for the webview is a url for a asp.net web application running on localhost. The url has javascript functions written in it. My question is how can i call javascript function written in web application from the uwp webview control.

<Page
x:Class="signalRonRPi3.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:signalRonRPi3"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<StackPanel>
    <Button x:Name="callJS" HorizontalAlignment="Stretch" Margin="0,0,298,0" Click="callJS_Click" >Call JS</Button>
    <WebView x:Name="webViewUrl" Source="http://localhost:52527/Home/Image" Height="500" Width="500" Margin="50" />
</StackPanel>

How do i call a javascript function written in the source url from here?

If I understood your question correctly. You want to invoke the Javascript within the source url. In that case you can use InvokeScript method.

You can refer this question on StackOverflow How to invoke javascript functions in a WebView in Universal Windows App to get more details.
