ComboBoxTranslateValue
-----------------------------------------------------------------------------
Demonstrates how to use C1ComboBox.TranslateValue property.

This sample shows how to bind C1ComboBox to datesource and translate value to Text using DataSource and TranslateValue properties.

At run time end-user can:
   - create new record in grid using "Add" button;
   - edit visible fields in grid;
   - edit invisible fields using edit form on the right;
   - choose application theme using C1ComboBox.

In this sample we have two data tables from the "C1NWind" database:
   1. Customer_demo (ID, LastName + some fields);
   2. Order (customerId + some fields).

Data binding:
   - C1ComboBox.Value is bound to the "CustomerID" field from the Order table;
   - C1ComboBox items are bound to the "Customer_demo" table and show "LastName" field content.

Point of interest:
	- setting C1ComboBox.TranslateValue property to true forces C1ComboBox to update text to proper lookup value when SelectedItem is changed.
	  In this sample it happens every time when end-user selects different data row in the grid.
