When auto generating a window, the Displayableattribute lets us select either a ComboBoxor a ListBox

This works for simple lookup tables, but sometimes the related entity is from a large table set and these options aren't practical. Rather than having to create a custom view, the following feature would be helpful...

Add a DisplayTypeof Searchable, and change WindowServiceto insert a selectable (for copy paste) but readonly textbox (maybe without borders?), that has a "Find" button next to it. This should pop up a re-usable search window that uses an auto generated DataGridand has a search function to filter results.

Things to bear in mind for this feature:

1. The use case for this feature is for large volume tables, so a filter that works on key press (UpdateSourceTrigger=PropertyChanged) will be impractical. It should have a textbox and an explicit "search" button.
2. To prevent excessive database activity related entities should not be loaded, and a check needs to be put in which will actively exclude those columns from the grid displayed to users.
3. It should only be available from DataEntryViewModelBase<T, Context> as this is the base class for ViewModels which are designed to be used with Entity Framework. Other bases can be used with or without EF so this default functionality wouldn't be appropriate.
