How to properly reference a class from XAML [closed]

Answer 1

OK... it suddenly started working. Just had to rebuild.

Answer 2

You can add a key so you can set the datacontext in the xaml instead behind code:

   <local:RangeValuesEditTemplateSelector x:key="RVETS">

Then for example set the outer grid's DataContext:

   <Grid DataContext={Binding Source = {StaticResource RVETS}} //Something like this I think

Then anything within that grid you can just bind directly to the property you set behind code. Not sure if this is useful or not, just thought I'd share :)
