Based on this solution i tried to call a JavaScript function located in my WebBrowser - control. The .xaml looks like this
<Grid>
<WebBrowser x:Name="browser"/>
</Grid>
But neither this code
public MainWindow()
{
InitializeComponent();
browser.NavigateToString("<html><script>function callMe() {alert('Hello');} document.myfunc = callMe;</script><body>Hello World</body></html>");
dynamic doc = browser.Document;
doc.myfunc();
}
Error
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: ''mshtml.HTMLDocumentClass' does not contain a definition for 'myfunc''
nor this Code
public MainWindow()
{
InitializeComponent();
browser.NavigateToString("<html><script>function callMe() {alert('Hallo');}</script><body>Hello World</body></html>");
browser.InvokeScript("callMe");
}
Error
System.Runtime.InteropServices.COMException: 'Unknown name. (Exception from HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))'
do work.
What am I missing?

Try this:
browser.NavigateToString("<html><script>function callMe() {alert('Hello');} document.myfunc = callMe;</script><body>Hello World</body></html>");
browser.LoadCompleted += (s,e) => browser.InvokeScript("callMe");
