C# – WebBrowser Control Focus

browsercnetwebwpf

Hopefully someone will be able to help.

I've embedded a WebBrowser Control into my C# WPF application and this works perfect with touches and mouse wheel movements (I've embedded a Google Maps page).

However as soon as I open another application then go back to my C# Application the WebBrowser Control has lost focus which then stops touches and the mouse wheel from working.

The only way I can get it working again is to TAB until the focus is back on the WebBrowser Control. I've tried setting the Focus() on the WebBrowser Control but it never seems to get the focus back.

Any Ideas?

Set Focusable to true before calling Focus(). default value for Focusable is false.

webBrowser1.Focusable = true;
webBrowser1.Focus();

C# – MetadataException: Unable to load the specified metadata resource

This means that the application is unable to load the EDMX. There are several things which can cause this.

You might have changed the MetadataArtifactProcessing property of the model to Copy to Output Directory.
The connection string could be wrong. I know you say you haven't changed it, but if you have changed other things (say, the name of an assembly), it could still be wrong.
You might be using a post-compile task to embed the EDMX in the assembly, which is no longer working for some reason.

In short, there is not really enough detail in your question to give an accurate answer, but hopefully these ideas should get you on the right track.

Update: I've written a blog post with more complete steps for troubleshooting.

WPF and initial focus

This works, too:

<Window FocusManager.FocusedElement="{Binding ElementName=SomeElement}">

   <DataGrid x:Name="SomeElement">
     ...
   </DataGrid>
</Window>
