Description

Perform the following steps to complete this task: 

1. Use EditCellTemplate to define MVC DropDownBox for a required column.
2.  Implement the Template function to define MVC DataGrid and handle its selectionChanged event to pass selected keys to DropDownBox. In addition, handle the dxDropDownBox.valueChanged event to adjust the DataGrid selection
3. Use CellTemplate to covert an array of selected keys to a human-readable text.
